Filler pastes used in Bayesian for coating polyolefin substrates, these types of Bayesian, and methods for directly painting polyolefin substrates.

摘要

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