Abstract: An alkoxysilyl-containing polyurethane polymer composition is prepared using a urethane-forming organometallic catalyst which is then stabilized to moisture exposure by the addition of a mercapto-containing compound. The stabilized moisture-curable alkoxsilyl-containing polyurethane polymer composition is activated to moisture curing by the addition of a hydrolysis and condensation catalysts. The stabilized moisture-curable alkoxsilyl-containing polyurethane polymer composition is useful as a component in the preparation of coatings, adhesives, sealants, consumer goods and industrial goods.

Abstract: A process for producing a silylated product comprises reacting a mixture comprising (a) an unsaturated compound containing at least one unsaturated functional group, (b) a silyl hydride containing at least one silylhydride functional group, and (c) a catalyst, optionally in the presence of a solvent, to produce a dehydrogenative silylated product, a hydrosilylated product, or a combination of a dehydrogenative silylated product and a hydrosilylated product, wherein the catalyst is chosen from a pyridine diimine cobalt dicarboxylate complex or a cobalt carboxylate compound, and the process is conducted without pre-activating the catalyst via a reducing agent and/or without an initiator or promoter compound. The present catalysts have been found to be active in the presence of the silyl hydride employed in the silylation reaction.

Abstract: A coated graphite heater. The heater has a configuration comprising a plurality of heating elements having a major portion disposed parallel to an upper surface of the heater so that the major portion is disposed horizontally. The heater configuration provides a heater that exhibits reduced thermal stress and/or reduced CTE mismatch stress particularly compared to designs having heating elements with a major portion oriented perpendicular to the plane of the upper surface of the heater.
