초록 ▼

The present invention is directed to a high-solids polyurethane reactive coating system based on blocked NCO-prepolymers, polyamines and, optionally, solvents, said coating system containing a leveller agent comprising (1) a combination of from about 1 to 10% by weight of (A) vinyl polymers and copolymers based on (meth)acrylic acid esters and, optionally, other comonomers and from about 0.1 to 2% by weight of (B) polysiloxanes and/or polyalkylene oxide/polysiloxane copolymers, (2) from about 0.2 to 2.0% by weight of (C) poly(meth)acrylic acid (hydroxy)alkyl ester graft polymers on silicones, (3) mixtures of (A), (B) and (C) in the amounts specified, (4) mixtures of (A) and (C) in the amounts specified or (5) mixtures of (B) and (C) in the amounts specified. The present invention also relates to textile substrates coated on one or both sides or surface-textured sheet-form materials, particularly velour leather, coated with the above leveller-containing, high-solids polyurethane reactive coating systems.
