ABSTRACT:
Multilayer radiation curable liquid coating compositions are provided that include one or more UV oligomers including at least one aliphatic urethane acrylic oligomer; at least one acrylate diluent monomer selected from a mono-, bi-, and tri-functional reactive acrylate diluent monomers; at least one photo-initiator; at least one UV absorber; at least one hindered amine light stabilizer; and at least one antioxidant, where the liquid composition does not comprise a solvent and does not comprise an adhesion promoter. The UV oligomer in the base coat composition has elongation higher than 200% and tensile strength lower than 1000 psi. The UV oligomer in the top coat composition has tensile strength higher than 5000 psi. A coating system is provided that includes a liquid primer coat composition, a liquid base coat composition and a liquid top coat composition. The cured film has good electrical insulation and UV resistance, and passes thermal cycle, damp heat and humidity freezing tests that are part of UL certification processes. The coating compositions are useful for coating substrates including SiOx substrates.
