用于水性底漆的填料组分

Filler component for use in aqueous basecoats
摘要：
The present invention relates to a process of multi-layer coating using a filler component comprisinga1) from 10 to 70% by weight of an aqueous dispersion of a water-dilutable polyurethane resin or of a plurality of water-dilutable polyurethane resins, the content of polyurethane in the aqueous dispersion being from 10 to 60% by weight, preferably from 20 to 50% by weight,a2) from 0 to 30% by weight of one or more amino resins and/or of a blocked polyisocyanate,a3) from 0 to 50% by weight of one or more physically drying binders which are different from a1),a4) from 5 to 40% by weight of one or more fillers and/or extenders,a5) from 0 to 30% by weight of color pigments and/or effect pigments,a6) from 0 to 5% by weight of one or more rheological auxiliaries and/or paint auxiliaries, anda7) from 0 to 10% by weight of organic solvent.The filler component is used to modify an aqueous basecoat composition, which is applied and followed by application of an aqueous basecoat second layer, a clear coat third layer, and then curing the coating layers together.
