Combining Polyester and Epoxy Chemistries for Optimal Performance of UV Powders

SpecialChem / May 20, 2009

Powder coating cured by ultraviolet light (UV powder) is a technology that combines the advantages of thermosetting powder coatings with those of liquid ultraviolet-cure coating technology. The difference from standard powder coatings is that melting and curing are separated into two distinct processes: upon exposure to heat, UV-curable powder coating particles melt and flow into a homogeneous film that is crosslinked only when it is exposed to UV light...
