This will make it clearer, and therefore the evaluation will also be based on this detail. This should be done taking the explanation into consideration. Detailed Description of the Invention In this detailed explanation, the coating system that creates a mirror image is not only better understood than the actual product. in order to facilitate understanding and without imposing any limiting effects It is explained. The invention relates to kitchen equipment with a polished aluminum surface that comes into direct contact with a flame. A mirror-like image created by spraying, consisting of a base layer and a top layer. This relates to the resulting silicone-modified polyester-based coating system. As is known, the difference between dyes and pigments lies in how light interacts with the material. This is due to their modes of interaction. These interaction modes affect transparency in coating formulations. There are significant differences in this regard. Dyes dissolve at the molecular level. and in the medium in which they are dissolved, they form a chemically homogeneous mixture. They allow the passage of light. By absorbing specific wavelengths without blocking them, it provides only the desired color. Therefore... Light can largely pass through a coating containing dye, which is then transparent. They create a visual effect. Pigments are insoluble and formed on a micron or nanometer scale. They are solid particles and form a suspension in the environment where they are dispersed. Therefore, coatings In these formulations, pigments create an opaque appearance, while dyes create a transparent appearance. Due to the known technical properties of pigments and dyes, the following arises within the scope of the invention. in the coating system applied, in the mirror-image substrate, in the polar solvent system Bright and vibrant colors along with transparency are achieved using soluble dyes. This is ensured. In the solvent system, soluble dyes are more resistant to external factors. Due to its low durability, the top coat formulation of the coating system subject to the invention is also... It is also gaining importance. The coating system described in the invention should be easily dispersed, homogeneous and standard in mass production. For application purposes, non-shedding aluminum pigments are preferred. Aluminum with a non-leaf structure has a higher yield compared to aluminum with a leaf structure. It creates a low mirror effect. In order to eliminate this disadvantage, the substrate In formulation 35, the particle sizes of aluminum pigments are adjusted for a clearer mirror image. Studies have been conducted on solvent systems. Therefore, the solvent system used is... homogeneous dispersion of non-foliating aluminum pigments 5 It is designed to provide orientation. Non-foaming aluminum pastes. The disadvantage is eliminated by considering the effect of the solvent system on orientation. It has been removed. In mirror-effect coatings, the particle size of aluminum pigments affects the coating's appearance. It directly affects its optical properties and reflectivity. Therefore, the obtained Different decorative appearances can be achieved in coatings by selecting the correct particle size. Every shiny surface is also reflective, but not every reflective surface provides a clear image. It is unable to create. A surface being shiny means it reflects some of the light back. It carries. However, the reflection effect also depends on how much of the light is reflected properly. The particle size of the aluminum pigments used in the invention varies. As it grows, the reflective effect on the surface also changes, resulting in a metallic sheen. reflections similar to mirror images of small particle-sized aluminum pigments It has been observed that a mirror image is obtained with the coating system that is the subject of this invention. To achieve this, aluminum pigment with a particle size of 13.5±1.5 microns (D50) was chosen. Dye that is soluble in the polar solvent system used in the substrate formulation. the low resistance of materials to external factors and in kitchen cooking utensils Due to the lack of suitable flame resistance, the top layer formulation in the invention It was created accordingly. The top layer, designed with this in mind, was modified with 30% silicone. Polyester resins were used in the production process. The final coating is non-yellowing and flame-retardant. It has durability, high chemical resistance, and a brighter, more reflective mirror image. Coatings with this feature have been obtained. Coating solutions offered in known technology generally do not provide flame resistance, It has low chemical resistance. However, the superior resistance achieved within the scope of the invention... The layer provides flame resistance and high chemical resistance on surfaces in direct contact with flame. It offers coating solutions for kitchen equipment. The top layer formulation also improves the physical performance of the invention. It is also designed to increase its brightness. The coating system described in the invention consists of two basic coatings: a substrate and a top layer. It consists of formulations. The combined use of these coatings enhances the design of the invention and 35 forms the basis of its functionality, and each coating formulation stands alone. When used, the technical effects described in the invention cannot be achieved. Table-1 shows the substrate. The formulation, specifically the top layer formulation, is given in Table 2. 6 Table-1: Substrate formulation; Content Preferred by Weight Available by Weight Quantity (%) Quantity (%) Methyl ethyl ketone 28 25-30 Butyl acetate 56 50-60 Xylene 10.2 10-12 Coloring agent 4.5 4-5 Aluminum pigment 1.3 1-1.5 Table 2: Top layer formulation Content Preferred by Weight Available by Weight Amount Obtained (%) Amount (%) 30% silicone modified polyester 40 resin (SMP) 35-45 Solvent 58 55-63.7 Rheology agent 1 0.5-1.5 Silicone oil 1 0.8-2 The coating system described in the invention, which has a mirror image, is based on a substrate that provides the mirror image. It consists of a protective silicone polyester-based top layer. The underlying layer that provides the mirror image generally includes the following components:  Solvents  Aluminum Pigments  Dyes; The fluidity of the resulting coating, the application properties of the coating, and the liquid quality of the coating its stability affects its primary function as a carrier for non-volatile components. In addition, solvents help the different organic components that make up the coating to mix together. By allowing it to dissolve, it reduces the drying time of the coating and improves adhesion to the surface. It affects its properties. After the solvents in the coating evaporate, the coating returns to its original state. The remaining portion is fixed to the surface. When designing solvent systems, the viscosity of the coating is considered. many factors have an effect on it, such as boiling point, surface tension, vapor pressure, and evaporation rate. Factors are taken into consideration. All these properties mentioned in solvent selection affect the coating. It affects its characteristics and quality. 7 Aluminum pigments are used to achieve a mirror-like appearance in many decorative coatings. It is used. The main reason why aluminum pigments create a mirror effect is this. The pigments consist of metallic structures with high reflectivity. Aluminum is visible. It reflects a large amount of light, which creates a "mirror image" in coatings. It is helpful. Other metallic-effect mother-of-pearls used besides aluminum and Since the pigments do not have high reflectivity, they cannot produce the same mirror effect. The behavior of aluminum pigments on the coating surface, foliation and It is characterized by two main features: lack of leaf formation. Due to its leafing property, aluminum pigments rise to the surface within the coating and They are arranged in overlapping layers. The pigments deposited on the surface are foliated. When the lights are aligned parallel to each other, most of the light is reflected back, which is why mirrors are used. It creates a similar appearance. Coatings obtained with these pigments have high... It provides brightness, reflectivity, and a metallic appearance. Thanks to its non-leafing property, aluminum pigments are homogeneously distributed within the coating. It disperses in this way and does not rise to the surface. This situation is more common in coating formulations. It provides a matte and even metallic effect. Non-foaming aluminum. The mirror effect in pigments is lower compared to pigments that are applied in leaves. The particle size of aluminum pigments determines the optical properties and reflectivity of the coating. This has a direct impact. Therefore, the correct particle size selection is crucial in the resulting coatings. Different decorative looks can be achieved with this. The invention allows for easy dispersion in solvents, resulting in homogeneous and standardized products in mass production. Non-shedding aluminum pigments were preferred for the application process. Aluminum with a non-leaf structure has a higher yield compared to aluminum with a leaf structure. It creates a low mirror effect. In order to eliminate this disadvantage, the subject of the invention... In the coating system, aluminum pigments are used as particles for a clearer mirror image. The dimensions and solvent systems have been discussed. The top layer formulation is the subject of the invention. In order to improve both the physical performance and the gloss of the coating system By designing it, the disadvantage of non-foliating aluminum pigments has been eliminated. Within the scope of 35 inventions, studies were conducted with aluminum pigments of different particle sizes. and aluminum pigment with the most suitable particle size for mirror image is preferred. It has been done. 8 Generally, substances used in coloring are divided into two categories: pigments and dyes. They can be examined in the group. Dyes are soluble in coating formulations. While chemicals, pigments are only incorporated into coating formulations through dispersion. It can add color. When dyes are mixed with a suitable solvent, they dissolve. The process is taking place. Dyes that are soluble in the solvent system, organic. These are dyes that are soluble in solvents but insoluble in water. This is typical. Some examples of solvents include alcohols, ethers, ketones, aliphatic and aromatic hydrocarbons. It can be given as follows. The difference between dyes and pigments lies in the way light interacts with the material. This is the source of these interaction patterns, which have an impact on transparency in coating formulations. They show significant differences. Dyes dissolve at the molecular level, and They form a chemically homogeneous mixture in the medium in which they are dissolved. They allow light to pass through. By absorbing specific wavelengths without blocking them, it provides only the desired color. Therefore... Light can largely pass through a coating containing dye, which is then transparent. It creates an appearance. Pigments are insoluble solid particles that form on a micron or nanometer scale, and Pigments form suspensions in the medium in which they are dispersed. Pigments scatter or reflect light. Light scattering is the dispersion of light within a material. This causes reflection, which results in the coating not being transparent. The particle size and shape of pigments can also affect light scattering. The pigments... Larger dimensions cause more light scattering, which in turn affects the coating. This causes it to appear opaque. While dyes absorb light and provide a transparent appearance, pigments scatter light and Because they reflect light, they cannot provide transparency. Therefore, in coating formulations... Pigments create an opaque appearance, while dyes create a transparent appearance. Dyes that are soluble in solvent systems are generally applied chemically to the surface to be painted. It does not form a bond. Instead, when the solvent evaporates, it dissolves on the surface. It retains its color while remaining in this state. It dries quickly due to the rapid evaporation of the solvent. It provides solvent-soluble dyes with high gloss and vibrant colors. They provide a range of colors, making them particularly ideal for bright and intense color applications. It reduces the pigments to 35. The pigments provide opaque colors and achieve a more matte look. is being done. 9 Dyes are generally less durable than pigments and are more susceptible to external factors. Pigments can fade over time when exposed to various factors (such as UV rays and chemicals). It is durable, therefore suitable for outdoor applications and where long-term durability is required. They are preferred in various fields. Consequently, dyes that are soluble in solvent systems are used. While providing bright, vibrant colors and transparency, the pigments are more opaque, durable, and long-lasting. It is preferred for long-term use. In addition to its mirror image, it offers high brightness. dyes for coloring the coating system that is the subject of the invention without giving up It has been used. Therefore, the coating system that is the subject of this invention has brightness, vibrancy and transparency. Dyes were chosen to provide the desired appearance. They are soluble in the solvent system. Due to the fact that the dyes in question are less resistant to external factors, the subject matter of the invention Top coat formulation has become crucial for coating systems. The manufacturing method of the coating system described in the invention: The substrate production method takes 4-5 minutes, depending on the preferred color intensity in the solvent. The dye was mixed in gram amounts and allowed to disperse for 45 minutes. Dye that is soluble in a solvent system that provides complete dissolution - solvent In order to obtain a mirror image of the mixture, the particle size (D50) was 13.5±1.5; 18±1.5; Mixing for 15 minutes by adding different aluminum pastes in the range of 30±1.5 microns. This has ensured that the aluminum pastes have been dispersed further. These pastes have different particle sizes. Mirror image visuals obtained using the method were compared. Table 3 shows the particles. The appearance information obtained according to its size is given. Table 3: Variations in appearance obtained according to aluminum pigment particle size. Aluminum Pigment Appearance Particle Size (D) 50 13.5±1.5 Mirror image 18±1.5 Metallic luster 30±1.5 Metallic gloss Every shiny surface is also reflective, but not every reflective surface provides a clear image. It does not create. A surface being shiny means it reflects some of the light back. It carries light. However, the reflection effect depends on how much of this light is reflected properly. The particle size of the aluminum pigments used in this invention varies. As it gets larger, the reflection on the surface changes, resulting in a metallic sheen, while smaller Mirror-like reflections occur in particle-sized aluminum pigments. It has been observed. Therefore, in order to obtain a mirror image in the invention, (D50) 13.5±1.5 microns Aluminum pigment with a particle size of 10 was preferred. Within the scope of this invention, factors such as surface tension, viscosity, and drying time are taken into consideration. A solvent system has been designed for the orientation of the products by taking this into account. With this technique, the substrate immediately afterward, the top layer is applied without the need for pre-drying, and the aluminum... The pigments have been designed to form a smooth film layer. The solvent mixtures used in this invention ensure both the homogeneous application of aluminum pigment to the surface. ensuring even spreading and balanced drying during the application of the top layer. It has ensured the duration. Technically designed for product orientation, the solvent system, each by allowing both layers to be applied smoothly and creating a mirror effect. It contributed to its formation. The top layer, which provides flame resistance and chemical resistance, generally includes the following: It includes the components.  Connectors  Solvents  Pigment and Filler Materials  Additives Silicone-modified adhesive is used as a binder in obtaining the top layer formulation. Polyester resin (SMP); silicone structure to increase the air and heat resistance of polyester resins. They are created by modifying them with binders. Coatings created with these binders are both silicone-based. It also reflects the properties of polyester compounds. Within the scope of the invention, between 30% Polyester resins modified with a silicone structure were used. Polyester While resins generally offer hard, chemically resistant and good mechanical strength, silicones are flexible, They are hydrophobic and have high temperature resistance. Due to their structure, silicones cannot come into direct contact with flame. resistance to external factors such as high temperature and oxidation to which it is exposed during processing While this is ensured, polyester provides resistance to solvents and acids. At the same time As the silicone content increases, the temperature resistance of the silicones and their resistance during curing also increase. The potential yellowing rate has also been minimized. Accordingly, the invention has a 30% reduction in yellowing. Among these, polyester resins created by modifying them with a silicone structure are preferred for the final product. The coating should not yellow, be flame-resistant, highly chemically resistant, and brighter. Coatings with a reflected mirror image have been obtained. 35. Additives improve coating performance depending on the type and intended use of the coating. They are added to enhance, solve problems, and see specific effects. These chemicals are 11 Superior properties such as coating spreading agent, dispersion, gloss, and rheology regulator. These are the chemicals that add. Rheology modifiers are used to determine the behavior of the coating inside the box, its applicability, and its different characteristics. It affects many of its characteristics, such as application methods, distribution, production, and storage. Silicone oil is characterized by its low surface tension, film-forming abilities, and spreading properties. They are quite important in coatings. The production method of the top layer; In the production of silicone polyester coatings; the product is tested in preliminary laboratory trials. silicone with 30% silicone content in different ratios such as 30%, 40%, 50% to create it Mixing of modified polyester resin, rheological agent, silicone oil and solvent mixtures. The process allowed the coating to disperse in 60 minutes. The coating was designed with the solvent system in mind. Many factors are considered, such as boiling point, surface tension, vapor pressure, and evaporation rate. It has been designed taking this into consideration.
