| 摘要 |
The invention relates to a coating composition comprising short chain fluorinated acrylates and to the use of short chain fluorinated acrylates as levelling agents for pigmented and unpigmented coating compositions. The coating composition comprises a) a film forming binder resin, and b) a copolymer made by controlled polymerisation or by conventional radical polymerisation comprising a monomer (M1x) selected from unsaturated monomers out of the group of (meth)acrylates, styrenic monomers or (meth)acrylamides whereby the copolymer contains at least >30 wt % (meth)acrylates; and a monomer (M2y) selected from C1-C4-fluoralkyl(meth)acrylates; x denotes the total number of monomers M1 within the structural element (M1x): x>5, preferred, 10-1000, most preferred, 10-500; y denotes the total number of monomers M2 within the structural element (M2y): y>1, preferred, 2-20, most preferred 2-10; c) optional other conventional coating components and/or additives.
