Description

Technical Field

[0002] Dry powder adopts full siliconization process, has good flowability and long service life, and is suitable for various places such as petrochemical enterprises, industrial and mining enterprises, hotels, hotels and schools. Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. Powder coatings are divided into two categories: thermoplastic and thermosetting. The film appearance (gloss and leveling) of thermoplastic powder coatings is poor, and the adhesion between them and metal is also poor, so they are rarely used in the field of automobile coating. Automobile coating generally uses thermosetting powder coatings. Thermosetting powder coatings use thermosetting synthetic resin as the film-forming material. During the drying process, the resin first melts and then solidifies into a smooth and hard coating film after chemical cross-linking. The appearance of the paint film formed by this kind of coating, various mechanical properties and corrosion resistance can meet the requirements of automobile finishing.
