COMPOSITION COMPRISING SILYLATED POLYMERS

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to a tin-free compositions suitable for making a coating comprising at least one silylated polymer and at least one polyhedral oligomeric metallo silsesquioxane. Invention also relates to a process of curing a composition comprising a silylated polymer, comprising the step of contacting a silylated polymer with a tin-free polyhedral oligomeric metallo silsesquioxane.;EFFECT: use of tin-free polyhedral oligomeric compounds of metallo silsesquioxane as hardeners increases the hydrolysis rate and condensation of organofunctional alkoxysilyl and/or silanol groups, id est improves the curing characteristics.;17 cl, 1 dwg, 7 ex
