DUAL-CURABLE COATING COMPOSITION BASED ON COMPOUNDS CONTAINING POLYASPARTATE, POLYISOCYANATE AND ACRYLATE

摘要

PROBLEM TO BE SOLVED: To provide a radiation-curable coating composition and a substrate coated with the coating composition.

SOLUTION: The composition includes: (a) an amino functional polyaspartate; (b) a (cyclo)aliphatic polyisocyanate; (c) an acrylate-functional compound; and (d) a photoinitiator; wherein the sum amount of the polyaspartate (a) and the polyisocyanate (b) is 15-70 wt.% of the composition; the amount of the acrylate functional compound (c) is 30-85 wt.%; and the amount of the photoinitiator (d) is 0.3-10 wt.% of the composition.
