Abstract
A poly(vinyl chloride) (PVC) based plastisol composition including a poly(vinyl chloride) polymer (homopolymer or copolymer), a plasticizer, and an infrared-reflective pigment is applied in a layer on a substrate and coalesced to produce a PVC layer including an infrared reflective pigment. The layer can be made into a free film and applied to an extruded vinyl or metal sheet to prepare vinyl or metal siding or trim pieces with an outer layer of the PVC including an infrared-reflective pigment.
Claims20
A method of making a laminated article, comprising:
- (a) removing a film from a backing material, wherein the film comprises a poly(vinyl chloride) polymer, at least one plasticizer, and an infrared-reflective pigment in a sufficient amount so that there is essentially no transmittance of light of near infrared wavelength through the film;
- and
- (b) laminating the film to a substrate.
A method of making a coated article, comprising:
- (a) forming a film comprising a plastisol coating composition comprising a poly(vinyl chloride) polymer, at least one plasticizer, and an infrared-reflective pigment;
- and
- (b) laminating the film to a substrate to form the coated article.
A method of making a laminated article, comprising:
- (a) removing a film from a backing material, wherein the film comprises a poly(vinyl chloride) polymer, at least one plasticizer, and an infrared-reflective pigment in a sufficient amount so that there is essentially no transmittance of light of near infrared wavelength through the film, and wherein the film has a thickness of from 2 mils to 5 mils;
- and
- (b) laminating the film to a substrate, wherein laminating the film to a substrate comprises the substrate having a temperature of 370° F. to 450° F.
