Abstract: A moisture-cure composition is described that includes a) at least one silane-functional polymer P; b) at least one catalyst for cross-linking of silane functional polymers; and c) at least 65% w/w of at least one filler, wherein the composition in the fully cured state has a Shore A hardness of ?60, determined in accordance with DIN 53505, and prior to curing has an extrusion pressure of ?1000 N.

Abstract: 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.
