ABSTRACT: Silane terminated prepolymers
for adhesives, sealants and coatings are of great industrial importance. They are
very important because of their low toxicity over polyurethanes, silicones, and solvent-based products. Hence,
many pieces of literature which deal with the synthesis, properties and
applications of this Silane terminated
polymers hybrid system exist. Silylated polyether (MS polymers) and Silylated Polyurethane Polymers (SPUR) are the bases
for numerous sealants, adhesives and
coatings used worldwide. A hybrid system mixed with organic-polyurethane proportion and inorganic-alkoxysilane
proportion combines the
benefits of conventional polyurethane and silicone-based products. This article reviews the chemistry of MS polymers
and SPUR and their advantages and disadvantages in silyl terminated
prepolymer-based adhesives, sealants
and coatings as well as provides information on different end applications.
