Abstract
An autoxidisable coating composition comprising i) 10 to 60 wt % of an autoxidisable material with: a) a number average molecular weight <4500 g/mol; b) optionally 1 to 20 carbohydrate units; c) a fatty acid content of ≧60 wt %; d) a viscosity at 100% solids in the range of from 0.05 to 5 Pa·s at 20+/−5° C. at a shear rate of 5000 s; ii) 90 to 40 wt % of an autoxidisable urethanised resin with: e) a number average molecular weight ≧4000 g/mol; f) a fatty acid content of ≧50 wt %; g) an acid value in the range of from 0 to 20 mgKOH/g resin; h) an isocyanate content in the range of from 1 to 35 wt % by weight of autoxidisable urethanised resin; where i)+ii)=100 wt %, based on the total solids content of the autoxidisable coating composition.
