摘要

polyurethane and / or polyurethane based bipartite hybrid system, coating composition, use of a polyurethane and / or polyurethane based bipartite hybrid system The present invention relates to a polyurethane and / or bipartite based hybrid system polyurethane polyurethane for making an elastomeric material, comprising an iso part provided with a low content monomer and an amine / polyol part, wherein the iso part comprises a polyurethane prepolymer, and wherein the prepolymer is a mdi-based prepolymer with low free mdi monomer and isocyanate group coating of a second isocyanate with relatively high vapor pressure, and the prepolymer contains less than about 0.3% total free monomer and has a nco % in the range from about 0.1 to about 10%.
