DOUBLEMER® 421P is a low viscosity, high purity, cycloaliphatic epoxide oligomer which undergoes rapid polymerization when exposed to UV light in the presence of a photoinitiator which generates a cationic catalyst. Onium salt photoinitiators are used to produce the cationic species on exposure to UV light, while remaining stable in the absence of UV light.
Formulations containing DOUBLEMER® 421P, along with other epoxide resins and polyol modifiers, can provide a range of cured film properties. Coatings containing DOUBLEMER® 421P generally have excellent toughness, solvent resistance, and good adhesion to a variety of substrates, including metals and plastics.
