SCRATCH- AND WEAR-RESISTANT COATING ON POLYMER SURFACES WITH CATALYTICALLY ACCELERATED HARDENING

The invention relates to a coating system, comprising two components A and B, wherein component A contains at least one reaction product of a silane Y(1)SiOR1OR2OR3 where Y(1) is a 3-glycidyloxypropyl group and similar or dissimilar alkyl groups R1, R2, R3 with 1 to 6 carbon atoms and water in the presence of a catalyst, selected from inorganic or organic acids and component B contains at least one reaction product of a further silane Y(2)SiOR'1OR'2OR'3 whereY(2) is a N-2-aminoethyl-3-aminopropyl- or NH2(CH2)2NH(CH2)2NH(CH)3 group and similar or dissimilar alkyl groups R'1, R'2, R'3 with 1 to 6 carbon atoms in the presence of an adjunct selected from ammonium compounds or hydroxides and at least one of the components A, B contains additionally at least one inorganic filler and a solvent with a boiling point of = 85 °C and a method for producing a surface coating on a polymer surface, characterised in that the fractions of the components A and B of said coating system (i) are mixed, then (ii) the composition obtained in step (i) is stored and then (iii) the composition obtained in step (ii) is applied to the substrate and then (iv) hardened in situ. The invention further relates to a an article with at least one polymeric surface, comprising said coating and the use of said article for the finishing of devices, fittings, instruments, measuring instruments, sanitary devices, cooking utensils, domestic devices, vehicle interiors, cockpits, displays, display windows, or furniture, and use of said articles as plates, bowls, moulded pieces, housings, knobs, levers, feet, doors, lids, bases, side walls, handles, ornamental inlays or splash guard elements.
