Abstract
The present invention provides a moisture-curing sealant comprising a) at least one silane-functional polymer and b) at least one catalyst for the crosslinking of the silane-functional polymer, said sealant being free of organotin compounds and having, in the cured state, a secant modulus at 100% elongation and 23° C., determined to ISO 8339, of less than 0.4 MPa and a resilience at 100% elongation, determined to ISO 7389, of greater than 70%. The sealant is especially suitable as a construction sealant of the 25LM class according to DIN EN ISO 11600, especially as a facade sealant, or as a sealant according to ASTM C719 Class 50.
