HIGHLY SCRATCH-RESISTANT MULTILAYER COAT, METHOD FOR PRODUCING AND USE OF THE SAME |
摘要 |
<p>The invention relates to a highly scratch-resistant multilayer coat on an optionally primed substrate, comprising the following layers which are superimposed on one another in the following sequence (A) a base coat layer (B) a first clear lacquer layer as an intermediate layer and (C) a second clear lacquer layer as the top layer. The multilayer coat is characterised i n that the second clear lacquer layer (C) can be produced from a coating material (C) which contains (C1) at least one oligomer and/or polymer, comprising at least one lateral carbamate group and/or allophanate group (c11), in particular, comprising a carbamate group (C11) of the formula: -O- (CO)-NH2; -O-(CO)-NH-(CO)-NH2 and (C2) at least one cross-linking agent whic h contains at least 2 functional groups (c21) that undergo cross-linking reactions with the carbamate group and/or allophanate group (c11). The invention also relates to a method for producing highly scratch-resistant multilayer coats.</p> |
