Abstract
Aqueous crosslinkable coating composition suitable for anti-graffiti and heavy duty applications comprising: (A) an aqueous polymer emulsion comprising at least one vinyl fluoropolymer which comprises as a polymerized constituent monomer thereof (i) a fluoromonomer(s) having the formula (1) wherein R1 is CH3 or H, R2 is a per-fluorinated C1-5 alkyl group and n is 1, 2, 3 or 4, (ii) a hydroxyl functional monomer(s) and (iii) a carboxylic acid-functional monomer(s) where the vinyl fluoropolymer has a glass transition temperature Tg within the range of from −50 to 90° C. and (B) at least one hydroxyl-reactive crosslinker material
