A biobased radical curable composition for coatings

A radical curable coating composition comprising

• 10 wt % to 70 wt % of one or more compounds A, based on the total weight of the coating composition,
• 30 wt % to 90% wt % of one or more (meth)acrylate compounds B, which are different from the one or more compounds A, based on the total weight of the coating composition, and
• 0 wt % to 25 wt % of one or more compounds C, different from compounds A and B, based on the total weight of the coating composition,
• wherein:
• each compound A comprises a poly(trimethylene ether) moiety and one or two (meth)acrylate groups,
• wherein the poly(trimethylene ether) moiety is incorporated into compound A by a condensation reaction of a poly(trimethylene ether) glycol with a (meth)acrylate compound selected from the group consisting of (meth)acrylic acid, (meth)acryloyl chloride, and alkylesters thereof,
• the poly(trimethylene ether) glycol having a number average molecular weight (Mn), measured by GPC with polystyrene as the standard, of from 900 to 5000 Dalton,
• each compound B comprises two or more (meth)acrylate groups,
• the one or more (meth)acrylate compounds B, combined, have a viscosity of at most 10000 mPa·s at 25° C. and have a weight average molecular weight of at most 4000 Dalton.
