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.
该发明包括二(烷氧基硅烷烷基)或三(烷氧基硅烷烷基)环戊烷,可能在其上有取代基,包括乙烯基,并且它们作为防水剂、在室温硫化硅密封胶中的交联剂、在涂料组合物中以及作为表面处理剂的用途。这些环烃是戊烷(C.sub.s)。硅烷基通过烷基连接到环上,该烷基可能在其上有取代基。多个硅烷基可以连接到环上。硅烷可能具有标准的取代基,包括烷氧基和卤素。在此考虑的具体硅烷具有以下公式:R.sub.a X.sub.3-a Si(CR'.sub.2).sub.n !.sub.b cycloC.sub.5 R".sub.10-b,其中R是烷基或芳基,X是1至4个碳原子的卤素或烷氧基基团、芳基氧基基团或肟基团,R'是1至3个碳原子的氢或烷基基团,R"是乙烯基、烷基、烯丙基、芳基、芳基氧基或烷氧基或氢,a=0、1或2,n=2至3,如果至少一个R"是乙烯基或烯丙基,则b=1至5,否则b=2至5。
