Abstract
Organopolysiloxane compositions that are storage-stable under anhydrous conditions, but curable into elastomeric state in the presence of moisture and, thus, are well suited as sealants and coatings and which particularly strongly adhere to substrates used in the construction industry, contain at least one .alpha., .omega.-dihydroxydiorganopolysiloxane polymer; at least one ketiminoxysilane crosslinking agent therefor; a bonding agent including admixture, or reaction product of, (i) an aminoorganosilicon compound containing a primary amine group, with (ii) an organosilicon compound containing an epoxy functional group; and, advantageously, a filler material and a curing catalyst.
