Abstract:
1. A solvent-containing polyisocyanate mixture having a solvent content of less than 50 weight % at a runout viscosity according to DIN 53211 at 23° C. of 20 s, an NCO content of from 7 to 15 weight %, a content of monomeric TDI of less than 0.2 weight %, and a content of monomeric aliphatic and/or cycloaliphatic isocyanates of less than 0.2 weight %, wherein said mixture consists of: A) a TDI component containing TDI isocyanurate polyisocyanates; B) an aliphatic and/or cycloaliphatic isocyanate component containing aliphatic and/or cycloaliphatic polyisocyanates; and C) the reaction product of at least one of components A) and/or B) with at least one polyether polyol having a number-average molecular weight of from 500 to 4000 g/mol that contains at least one tertiary nitrogen atom and optionally at least one polyether polyol that does not contain nitrogen atoms.
