Abstract

This disclosure relates to a curable composition comprising at least one polymer A with at least one reactive silyl group and at least one polymer B with at least one reactive silyl group, the number of reactive silyl groups in the polymer A being greater or equal to the number of silyl groups in polymer B and the reactive silyl groups being capable of cross-linking to form siloxane bonds. The disclosure also relates to preparations containing a composition of this type and to the use of said compositions.
