COMPOSITION BASED ON SILANE-TERMINATED POLYMERS THAT DOES NOT SPLIT OFF METHANOL DURING CURING

摘要

The invention relates to a composition including a) at least one silane-functional polymer P having alkoxy end groups, which are not methoxy groups; b) at least one catalyst for the cross-linking of silane-functional polymers, selected from the group comprising an organotitanate, organozirconate and organoaluminate; c) at least one compound having at least one amidino group. Such compositions are suitable as adhesives, sealants and coatings and have the advantage that the compositions are substantially free from tin or organic tin compounds and do not split off methanol during curing.
