RELECTIVE COATINGS AND IN-MOLD PROCESSES FOR THEIR APPLICATION TO POLYMER SUBSTRATES

Reflective coatings comprise a transparent binder, such as polyurethane, one or more reflective additives, such as metal flakes, coated mica or titanium dioxide particles, and a phosphor. Such coatings may be applied to polymer substrates such as polycarbonate, without any additional reflective coat...

Beschreibung
Zusammenfassung:	Reflective coatings comprise a transparent binder, such as polyurethane, one or more reflective additives, such as metal flakes, coated mica or titanium dioxide particles, and a phosphor. Such coatings may be applied to polymer substrates such as polycarbonate, without any additional reflective coating, film or layer. Processes for the mixing and applying the coatings area described, including introducing a polymer substrate into a mold cavity of a mold, introducing a coating composition into the mold cavity containing the polymer substrate in order to coat the substrate, at processing temperature 50° C.-120° C., at processing pressure 11,000 to 20,700 kPa, and curing the composition in the mold cavity at cure temperature of 62-105° C.
