UV CURED VARNISH AND PROCESS FOR PREPARING THE SAME

摘要

A UV cured varnish, and a process for preparing the same, said UV cured varnish including an epoxy acrylic resin, a polyurethane acrylic resin, a polymerizable monomer, a filler, a photoinitiator, and an adjuvant, wherein the polymerizable monomer comprises a fluorine containing polymerizable monomer and a silicon containing polymerizable monomer. The UV cured varnish can significantly improve the film forming performance. The formed film has a significantly improved performance including hardness, perspiration resistance. The UV cured varnish thus obtained is especially suitable for touch screen and can greatly extend the life of the touch screen.

主权项

1. A UV cured varnish, which comprises, in part by weight, 20-40 parts of an epoxy acrylic resin, 10-25 parts of a polyurethane acrylic resin, 5-30 parts of a polymerizable monomer, 10-30 parts of a filler, 1-6 parts of a photoinitiator, and 5-10 parts of an adjuvant,
wherein the polymerizable monomer comprises, by weight 35-70% of an acrylate and/or methacrylate monomer, 20-45% of a fluorine containing polymerizable monomer, and 10-25% of a silicon containing polymerizable monomer; and the silicon containing polymerizable monomer is selected from trimethylsilyl methacrvlate and/or 3-trimethoxysilylpropyl methacrvlate.
