A solid polymeric substrate having a resin derived from curable silylated polyurethane composition exhibiting superior properties adhered thereto. The silylated polyurethane is prepared by reacting a polyol component with a diisocyanate component to form a hydroxyl-terminated prepolymer and endcapping the prepolymer with an isocyanate silane.

In accordance with the present invention, a hydrolyzable silane of low VOC-generating potential is provided which possesses: Further in accordance with the invention, a resinous composition of low VOC-generating potential is provided which comprises:

Hydrolyzable silanes of low VOC-generating potential and resinous compositions containing same

Disclosed herein is a process for preparing a shelf-stable, one-pack, silane modified (meth)acrylic latex interpolymer composition, wherein the process comprises continuously adding at least a portion of a mixture comprising at least 0.5 mole percent of a vinyl silane comprising hydrolyzable groups and up to 99.5 mole percent of a (meth)acrylic monomer to water and a surfactant in a reaction vessel, wherein said addition is carried out in the presence of a polymerization initiator and buffer sufficient to maintain the pH of the reaction at a level of at least 6 throughout the reaction, while simultaneously hydrolyzing from about 10 to about 60% of the hydrolyzable groups of the vinyl silane.

Shelf-stable silane-modified aqueous dispersion polymers

A crosslinkable silane-terminated polymer is provided which includes the reaction product of an isocyanate-terminated prepolymer and a silane possessing a plurality of hydrolysable sites and at least one active hydrogen-containing group which is reactive for isocyanate, the silane upon hydrolysis produces a reduced amount of volatile organic compound compared to that produced by the hydrolysis of a silane possessing an equivalent number of hydrolyzable sites all of which are hydrolyzable alkoxy groups.

Crosslinkable silane-terminated polymer and sealant composition made with same

Novel hindered alkoxy siloxane compounds and compositions containing hindered alkoxy siloxane compounds are provided. The compositions include a polymer/crosslinking system which is composed of a self crosslinking resin comprised of a silicone fluid modified with pendant or terminal silanes containing hindered alkoxy groups, or a silanol fluid and a crosslinking compound, of a mixture thereof. These components are first emulsified and then formulated into a latex sealant by blending with a separate emulsion of an appropriate catalyst. Crosslinking occurs upon drying of the emulsion.

Waterborne silicone adhesives, sealants and coatings

Emulsions comprising a water insoluble or semi-soluble silane or mixtures of such silanes have been found useful when used alone or formulated into aqueous primer systems to improve the adhesion of sealants, adhesives or coatings to a variety of substrates. These aqueous primers are suitable for both inorganic and organic substrates having either porous or non-porous surfaces. In many cases they have been found to outperform solvent based primers. Primers of this type can be used with a variety of waterborne or solvent based sealants, adhesives or coatings including acrylic or polyurethane latexes, high solid polyurethanes, epoxies and silicones. When used with waterborne systems, it is not necessary to wait for the primer to dry before application of the sealant, adhesive or coating.

Use of emulsified silane coupling agents as primers to improve adhesives of sealants, adhesives and coatings

This invention describes the use of blocked mercaptosilanes wherein the hydrogen atom of the mercaptan functionality has been substituted to manufacture coating, adhesive, sealant and elastomeric compositions. The blocked mercaptosilanes described are unique in that they allow the application of elastomers to substrates to proceed while remaining inert toward coupling to the catalyst. The coupling reactions of these blocked mercaptosilicon compounds are triggered by exposure to an appropriate deblocking agent.
