Low Heat Build-Up UV-Cured Vacuum Coating System in Dark Colors

摘要

A weatherable, low heat build-up, UV-cured vacuum coating for PVC or other extruded plastic profiles comprising a dark-colored pigment system that is substantially IR transparent, an IR reflective substrate, and a vacuum coating system for same.

主权项

1. A heat build-up resistant extrudate with a dark-colored vacuum coating, comprising:
an IR reflective substrate portion formed of a thermoplastic resin that is substantially reflective of solar infrared radiation, a dark-colored vacuum coating that is formed of a UV-cured vacuum coating that is significantly transmissive of solar infrared radiation and that covers at least a portion of the reflective substrate, and wherein the extrudate exhibits a predicted horizontal heat build-up under ASTM D4803 of less than about 58° Fahrenheit.
