Abstract: A resin composition containing an organic resin (i) containing carboxylic acid ester and/or ether functional groups and optionally other halo groups, amino groups, hydroxyl groups, carboxylic acid groups and cyano groups and a moisture-curable silylated polycarbonate resin (ii) derived from a copolycarbonate diol, prepared from diol(s) having even numbers of carbon atoms and odd number of carbon atoms and coatings formulated using these resin compositions.
Abstract: A hydrophilic silicone, compositions comprising the same, and articles comprising the same are shown and described herein. The hydrophilic silicone is an ionically modified silicone compound wherein the compound comprises a zwitterionic moiety and has a net neutral charge. The hydrophilic silicone compounds may be provided as part of a composition, e.g., a composition suitable for forming a hydrogel, which may be employed to form a film material and even an article (e.g., in a contact lens).
Abstract: There is provided herein a silylated polyurethane composition, a process of preparing a silylated polyurethane polymer, and an adhesive, sealant or coating containing a silylated polyurethane made therewith.
Abstract: A moisture-curable composition is shown and described herein. The moisture-curable composition comprises a moisture-curable resin and a moisture scavenger selected from a cyanoalkylalkoxysilane. The inclusion of the cyanoalkylalkoxysilane in the moisture-curable composition has been found to effectively scavenge moisture and control the rate of curing and viscosity increase in the composition.

Abstract: Reactive poly(fluoroalkyl-functional siloxane) oligomers, method of making the same, and compositions comprising the same are shown and described herein. The reactive poly(fluoroalkyl-functional siloxane) oligomers are is derived from a hydrolysable fluoroalkyl-functional silanes. Coating compositions comprising reactive poly(fluoroalkyl-functional siloxane) oligomer(s) may be used to form a coating or a film on a substrate and impart hydrophobic and/or oleophobic properties. The reactive poly(fluoroalkyl-functional siloxane) oligomer are more hydrophobic and oleophobic and show better chemical resistance than the hydrolysable fluoroalkyl-functional silane.
