COATING AGENT FOR PRODUCING PLIABLE SCRATCH-RESISTANT COATINGS THAT REPEL DIRT, PLIABLE SCRATCH-RESISTANT SHAPED BODIES THAT REPEL DIRT AND METHOD FOR THEIR PRODUCTION

摘要

The invention relates to coating agents for producing pliable scratch-resistant coatings that repel dirt. Said agents comprise: A) between 1 and 30 wt. % of a prepolymer that is obtained by the radical polymerisation of a mixture comprising A1) between 1 and 10 parts by weight of at least one sulphur compound containing 3 thiol groups and A2) between 90 and 99 parts by weight of alkyl(meth)acrylates; B) between 0.2 and 10 wt. % of at least one fluoroalkyl(meth)acrylate with 3 to 30 carbon atoms in the alcohol group, which contains 6 to 61 fluorine atoms; C) between 20 and 80 wt. % of multi-functional (meth)acrylates; D) between 0.01 and 10 wt. % of at least one initiator; E) between 0.2 and 75 wt. % of at least one diluent; F) between 0 and 40 wt. % of conventional additives; G) between 0.01 and 10 wt. % of fluoroalkyl(meth)acrylate according to formula (I), in which the group R1 represents a hydrogen atom or a methyl group and the group R2 represents a fluorinated alkoxy group of formula O - CaHbFc, where a stands for a whole number ranging between 1 and 4, in particular 1 and 3, b stands for a whole number ranging between 0 and 4 and c stands for a whole number ranging between 2 and 4, preferably 2 to 4, where c=2a + 1-b. The invention also relates to pliable scratch-resistant shaped bodies that repel dirt and comprise a plastic substrate and a scratch-resistant coating.
