RADIATION CURABLE LOW GLOSS POWDER COATING COMPOSITIONS

摘要

A radiation curable powder coating composition for preparing low gloss coatings, comprises as a binder a mixture of 30 to 90 weight % of one or more (meth)acryloyl group containing amorphous polyester resins having an unsaturated equivalent weight of more than 700 g/double bond and an isophthalic acid content of from 65 to 100 weight %, calculated on all the acids, and 10 to 70 weight % of one or more (meth)acryloyl group containing acrylic copolymers having an unsaturated equivalent weight of up to 1250 g/double bond.
