ABSTRACT:
Room temperature vulcanizable silicone sealants containing acetoxy groups are fast curing. These sealants give off only small amounts of volatile materials which are generated during the curing process. These sealants contain crosslinkers and optionally chain extenders having azasilacycloalkane groups cure. The preferred azasilacycloalkanes are azasilacyclopentane groups such as ##STR1##
