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: The invention is directed to a detectable and stable composition comprising an organofunctional silane and/or hydrolyzate and/or partial or complete condensate thereof, a colloidal metal oxide, a water soluble organic dye having a positive charge and a counterion derived from a carboxylic acid of from 1 to 6 carbon atoms, and water. The invention is also directed to a method for determining the uniformity and film thickness of a detectable composition applied to a substrate comprising applying to the surface of the substrate the detectable composition and measuring an optical property of the applied coating, the resulting measurement being related to the uniformity of the applied composition.

Abstract: A silane based additive, rubber formulations including the additive and tires having tread portions made with the additive, together with methods of forming those products, are provided. Uncured rubber formulations in accordance with preferred embodiments of the invention comprise (1) a rubbery primary polymer or polymer blend, such as natural rubber and/or synthetic rubber; (2) reinforcing silica filler; (3) a network forming monomer or polymer, especially a thermosetting network forming moiety, for forming a secondary polymeric network; and (4) a silane containing one or more moieties of the aforementioned network forming polymer. In particular networks which can be generated in-situ are preferred. The cured rubber formulation should comprise the silica, having the secondary polymer network coupled thereto, within the rubber matrix, and not directly to the rubber chains via sulfidic linkages.
