摘要
The invention relates to copolymer solutions of copolymers of the abovementioned type, which, after the copolymerisation, has an unusually high solids content (about 80 % by weight) and can be converted, with polyisocyanates into two-component coatings having a high solids content and good processing viscosity. Copolymers contain a cocondensed methoxy-functional polysiloxane. The copolymers can be converted with amino resins into binders for stoving coatings (baking coatings or paints) which, as improved varnishes for automotive finishes, give paint films which have excellent abrasion resistance in automatic car washes.
