FILLER PASTES FOR USE IN BASE PAINTS FOR COATING POLYOLEFIN SUBSTRATES, BASE PAINTS OF THIS KIND AND METHODS OF DIRECTLY PAINTING POLYOLEFIN SUBSTRATES)

摘要

The present invention comprises a1) a polyurethane resin or a plurality of polyurethane resins, 5 to 50% by weight, preferably 30 to 45% by weight a2) having a number average molecular weight of 5000 to 150,000, based on the solids content of the chlorinated polyolefin At least one chlorinated polyolefin having a chlorine content of 40 to 40% by weight, 0.5 to 13% by weight a3) at least one physical dry binder other than a1), 0 to 50% by weight, preferably 0 to 10% by weight, a4) One or more fillers and / or weight agents, 5 to 35% by weight, a5) pigments of color and / or specific effect, 0 to 15% by weight, a6) one or more rheological aids, 0 to 5% by weight, and a7) a1 A filler paste (A) comprising an organic solvent, 20 to 60% by weight, of which the sum of the components) to a7) is in each case 100% by weight. The present invention also provides a process for applying a base coating (B) containing filler paste (A) directly to a polyolefin substrate, after a brief intermediate flash-off, applying a base coating without filler paste, and briefly applying the base coating. Flash and coating with a transparent coating, followed by curing with heating.
