METHODS FOR TAILORING THE PROPERTIES OF A REFLECTIVE COATING

Methods are provided for forming a reflective coating by applying a precursor material onto the substrate; soft curing the precursor material at a first curing energy level; and thereafter, hard curing the precursor material at a second curing energy level having a higher amount of energy than the f...

Beschreibung
Zusammenfassung:	Methods are provided for forming a reflective coating by applying a precursor material onto the substrate; soft curing the precursor material at a first curing energy level; and thereafter, hard curing the precursor material at a second curing energy level having a higher amount of energy than the first curing energy level to form the reflective coating. Other methods are provided for forming a reflective coating a surface of a plastic substrate by heating the surface of the plastic substrate to a deposition temperature, applying a polymeric resin onto the heated surface, and crosslinking the polymeric resin to form the reflective coating. The polymeric resin can include a cross-linkable powder, a cross-linker, and a pigment, with the deposition temperature being about 10° C. or greater than the melting point of the cross-linkable binder. Lighting apparatus formed from such methods are also provided.
