The present invention pertains to moisture curable sealant compositions based on alkoxysilane functional poly(ether-urethane)s prepared from hydroxycarbamoylalkoxysilanes which provide improved paint adhesion even in the absence of polar solvents or polar plasticizers. The present invention also provides coated substrates and laminates formed from such compositions.

Hydroxycarbamoylalkoxysilane-based poly(ether-urethane) sealants having

A granular material is presented comprising inorganic particles coated with an organometallic polymeric binder, the organometallic polymeric binder comprising the reaction product of water with at least one component of a binder precursor composition. The binder precursor composition is selected from the group consisting of 1) a first composition comprising an inert organic polymer and a hydrolyzable liquid organometallic solvent; 2) a second composition comprising a water reactive organic polymer dissolved in an inert organic solvent; and 3) a third composition comprising the water reactive organic polymer dissolved in the hydrolyzable liquid organometallic solvent.

Inorganic particles coated with organic polymeric binders composite

The present invention relates to novel reaction products of azlactones and organometallic nucleophiles and the method of making these reaction products. The invention also relates to methods of using such reaction products to prevent or eliminate microbial and fungal growth on substrates. Reaction products can be provided that show improved antifouling and antimicrobial action.

Organometallic acrylamide compositions and methods for making same,

An aigicidal composite sheet body suitable for use as a building material is described. The composite comprises a bituminous sheet material having a firmly adherent surfacing of granular material, the granular material comprising ceramic-coated base granules adhered to the bituminous sheet material by a composition containing calcium, the granular material and the composition forming an exterior surface on the composite sheet body, the composite sheet body exterior surface having an algicidal topical coating Thereon, wherein the algicidal topical coating comprises an organic oil and a tin-acrylate polymer dispersed therein, the tin-acrylate polymer being derived from a monomer composition comprising flee-radical polymerizable units. The organic oil is selected from the group consisting of slate oil, rock oil, coal oil, and seneca oil, and the tin-acrylate polymer is present at a weight percentage ranging from about 0.5 to about 15 as a percentage of total weight of the organic oil and the tin-acrylate polymer.

Tin-acrylate-containing polymers as algicidal agents in building

Granular materials having a tin-acrylate polymer coating are described which are algae-resistant. A method of inhibiting the growth of algae on roofing granules and other particulate materials attached to substrates by the use of tin-acrylate-containing polymers either as a topical treatment or as a polymeric binder is also presented. The methods presented are an advancement in the art in that in addition to algae-resistance, the polymers also confer other desirable properties to the granules onto which they are coated, such as increased adhesion to asphalt shingles.
