Non-hot-melt MDI-based polyurethane composition bearing NCO end groups and having a low content of MDI monomer, comprising at least one isocyanate compound of particular molar volume

摘要

1) Polyurethane composition comprising:a) at least 98% by weight of at least one non-hot-melt polyurethane bearing NCO end groups based on diphenyl methane diisocyanates (MDI),b) a MDI monomer content of less than or equal to 1% by weight,c) at least one particular isocyanate compound with a molar volume of less than or equal to 300 milliliters per mole.;2) Process for preparing a polyurethane composition as defined previously, and an adhesive, mastic and/or surface coating composition formulated from such a polyurethane composition.
