Composition, useful as adjuvant in the industry of the coatings, comprises isocyanate subcomposition comprising di-isocyanate monomers and isocyanate groups, and compound carrying dihydrocarbylsilylene groups

摘要

Composition (I) for successive or simultaneous addition, comprises an isocyanate subcomposition comprising di-isocyanate monomers (5, (preferably 0.5)%) and monomers resulting from amino acid and comprising a content of isocyanate groups (equal to 55%); and at least a compound carrying dihydrocarbylsilylene groups and hydrocarbyl (hydrocarbyloxy) silylene group. Composition (I) for successive or simultaneous addition, comprises an isocyanate subcomposition comprising di-isocyanate monomers (5, (preferably 0.5)%) and monomers resulting from amino acid and comprising a content of isocyanate groups (equal to 55%); and at least a compound carrying dihydrocarbylsilylene groups [-(Hc)2Si-] and hydrocarbyl (hydrocarbyloxy) silylene group [-(Hc)(Hc-O-)Si], attached to a metalloid of chalcogen column or to an atom of nitrogen column, content of such groups is at least equal to 0.1% (mass) and maximum to 3% expressed by mass of silicon atom (M.A. = 28.1) contained in a dihydrocarbylsilylene compared to the quantity of monomers corresponding to the units.
