摘要:
A multicomponent system comprising at least three components, comprising (I) a component which is free from chlorinated polyolefins and is curable with polyisocyanates, comprising (I.1) at least one binder containing isocyanate-reactive functional groups and (1.2) at least one organic solvent, (II) a component free from binders (I.1), comprising (II.1) at least one chlorinated polyolefin and (II.2) at least one organic solvent, (III) a component consisting of or comprising at least one polyisocyanate (III.1); processes for its preparation, and its use.
摘要:
Chromium-free, low-zinc, corrosion-inhibiting pigment mixture (A) comprising (a1) 30% to 60% by weight of at least one calcium hydrogen phosphate pigment, (a2) 15% to 45% by weight of at least one amorphous, calcium-modified silicon dioxide, (a3) 5% to 25% by weight of at least one calcium borosilicate pigment, and (a4) 1% to 15% by weight of at least one zinc salt of an organic nitro compound with the proviso that the zinc content of (A) does not exceed 10% by weight; process for preparing it, and its use.

摘要:
The abstract concerns a coating composition comprising 25-55% by weight of one or more film formers, 2.5-55% by weight of one or more fillers, 0-10% by weight of one or more additives, and 0-30% by weight of a solvent, based on the total weight of the coating composition. As the filler or a filler the composition comprises calcium hydrogen phosphate in a mass fraction of 2.5-20%, preferably 5-15%, more preferably 7.5-11% by weight based on the total weight of the coating composition. The invention further concerns processes for preparing this coating composition, its use as a coating material in the vehicle sector, and substrates produced therewith.
