Coating Agents for Producing Formable, Scratch and Soiling-Resistant Coatings, Scratch-Resistant, Formable and Soiling-Resistant Shaped Bodies and a Method for the Production Thereof

摘要

The present invention relates to coating compositions for producing formable scratchproof coatings with dirt repellency effect, comprisingA) from 1% by weight to 30% by weight of a prepolymer obtainable by free-radically polymerizing a mixture comprising A1) from 1 to 10 parts by weight of at least one sulphur compound containing at least 3 thiol groups andA2) from 90 to 99 parts by weight of alkyl (meth)acrylates,B) from 0.2% by weight to 10% by weight of at least one fluoroalkyl (meth)acrylate having 6 to 60 carbon atoms in the alcohol residue and including 13 to 121 fluorine atoms,C) from 20% by weight to 80% by weight of polyfunctional (meth)acrylates,D) from 0.01% by weight to 10% by weight of at least one initiatorE) from 2% by weight to 75% by weight of at least one diluent andF) from 0% by weight to 40% by weight of customary additivesG) from 0.01% by weight to 10% by weight of 2,2,3,3-tetrafluoropropyl methacrylate.Additionally disclosed are scratchproof/formable and dirt-repellent mouldings comprising a polymeric substrate and a scratchproof coating.
