Abstract
A composition containing two different silane-functional polymers, only one of the two polymers having terminal groups of formula (I). The composition has a surprisingly rapid skin forming time and low viscosity, crosslinks quickly even without the use of EHS-critical catalysts such as organotin compounds or DBU, and cures to a non-sticky material with good strength and elasticity. Also relates to a method for accelerating the curing of a silane-crosslinking composition by adding to it a further silane-functional polymer having terminal groups of formula (I).
