Abstract

This invention includes di- and tri(alkoxysilylalkyl)- or haloalkoxysilylalkylcyclic pentanes, which may have substituents thereon, including vinyl groups, and their use as waterproofing agents, as crosslinking agents in room temperature vulcanizing silicone caulks, in coating compositions and as surface treatments. The cyclic hydrocarbons are pentane (C.sub.s). The silane groups are attached to the ring through an alkyl group, which may have substituents thereon. Multiple silane groups may be attached to the ring. The silanes may have the standard substituents thereon, including alkoxy and halogens. The specific silanes contemplated herein have the following formula: R.sub.a X.sub.3-a Si(CR'.sub.2).sub.n !.sub.b cycloC.sub.5 R'.sub.10-b where R is an alkyl or aryl group, X is a halogen or an alkoxy radical of 1 to 4 carbon atoms, aryloxy radical or oxime group, R' is a hydrogen or alkyl group of 1 to 3 carbon atoms, R' is a vinyl, alkyl, allyl, aryl, aryloxy or alkoxy group or hydrogen, a=0, 1 or 2, n=2 to 3 and if at least one R' is a vinyl or allyl group, b=1 to 5, otherwise b=2 to 5.
