43 results about "Vinyl siding" patented technology

Vinyl siding is plastic exterior siding for houses and small apartment buildings, used for decoration and weatherproofing, imitating wood clapboard, board and batten or shakes, and used instead of other materials such as aluminum or fiber cement siding. It is an engineered product, manufactured primarily from polyvinyl chloride (PVC) resin. In the UK and New Zealand a similar material is known as uPVC weatherboarding.

Films or structural exterior materials using coating composition having self-cleaning property and preparation method thereof

Disclosed is a coating composition comprising: (a) hydroxy group-containing inorganic particles having an average particle diameter of between 5 and 30 nm; (b) hydroxy group- containing inorganic particles having an average particle diameter of between 0.2 and 5 D; (c) an organosilane compound represented by the formula of R n Si(OR') 4-n (wherein R is a C1-C8 aminoalkyl group, glycidoxyalkyl group or isocyanatoalkyl group; R'is a C1-C6 lower alkyl group; and n is an integer of between 0 and 3); and (d) a solvent. A method for preparing the above coating composition, a substrate such as film or structural exterior material, having excellent self-cleaning property and staining resistance by using the above coating composition and methods for producing the same are also disclosed. The coating composition using hydroxy group-containing inorganic particles can improve the initial hydrophilicity of conventional coating agents. Additionally, the coating composition can form a hydrophilic coating layer having a contact angle with water of 30 DEG or less by using two kinds of inorganic particles having a different particles diameter. Particularly, the coating composition uses an organic solvent having erosive property to a substrate to be coated and a low boiling point, and thus can be applied to a conventional production line for structural exterior materials without adding a separate coating line. Therefore, the coating composition can provide structural materials having hydrophilicity, excellent self-cleaning property and long service life, when coated on substrates such as vinyl sidings.
