B-295A Aliphatic polyurethane acrylate

B-295A is a bifunctional PUA resin with a special structure. The resin contains 15% IBOA monomer. Medium to low molecular weight, it has good adhesion and tensile strength at break. Due to its special rigid structure, the resin cures quickly, has good drying properties and has high surface hardness. Used for adhesives and UV plastic spraying, it can adjust the hardness and flexibility of the formula, and balance the formula's resistance to boiling, salt spray, high and low temperature, and hot and cold cycles; used in UV plastic varnish and vacuum plating formulas, Helps withstand boiling and high pH hand sweat.
