POSTFORMABLE ULTRAVIOLET CURABLE COATINGS

摘要

POSTFORMABLE ULTRAVIOLET CURABLE COATINGS A postformable ultraviolet curable primer coating composition is disclosed which consists essentially of: (A) from 10% to 80% of a linear acrylate-terminated polyurethane based on a polycarbonate diol; (B) from 2% to 35%, of acrylic acid; (C) from 15% to 65% of a monoethylenically unsaturated monomer having the rapid ultraviolet cure rate associated with acrylate monomers and having a glass transition temperature above 35.degree.C.,; (D) from 0% to 25% of a polyacrylate monomer; and (E) photoinitiator rendering the composition curable with ultraviolet light.
