Abstract:
METHOD OF MAKING MOLDED ARTICLES, PARTICULARLY OF FIBROUS GLASS, COMPRISING IMPREGNATING A SUBSTRATE WITH A MIXTURE OF A CURABLE VINYLIC RESIN AND AN ACRYLOXYALKYLSILANE AND SUBSEQUENTLY CURING TO FORM A CONSOLIDATED ARTICLE.
Abstract:
Silyl-functional fumarates are formed through the reaction of a methyl ester of a maleate with a chloroalkyl silane or disiloxane in the presence of an amine or phosphine catalyst. These materials are useful as adhesion promoters for polyolefins.
Abstract:
A novel ionomeric silane coupling agent is disclosed and its use in bonding a matrix polymer to a mineral substrate is described. The coupling agent is prepared by partially neutralizing the combined acid functionality present in a mixture of an acid-functional silane (or metal salt thereof) and an acid-functional film former with a metal ion. The coupling agent greatly improves bond strength in moist environments and is particularly suitable for use in formulating filled injection molding compositions.
Abstract:
Organosilicon quaternary ammonium antimicrobial compounds are described, particularly, ammonium chloride derivatives of multifunctional diamino quaternary salts, and salts containing a combination of amino, ester, and fluoroalkyl, functionality.
Abstract:
Salts of substituted nitrogen or sulfur containing siliconates are effective stabilizers for aqueous silicates in such applications as treating boiler water, geothermal water and other aqueous silicates. They are also useful in antifreeze and cooland solutions.
Abstract:
The preparation and applications of anionic siliconate-zeolite composites are disclosed. The composites are formed by coating the surface of zeolite particles with an aqueous solution of an anionic functional organosiliconate. The composites are particularly useful as components of soluble silicate containing detergent compositions since they do not agglomerate with the soluble silicates to form large insoluble particulates that can deposit on fabrics during laundry. Detergent compositions containing the composites are disclosed.
Abstract:
What is disclosed are novel compositions of matter which are alkali siliconate silylalkylphosphonates which are capable of stabilizing water soluble silicates and which are capable of inhibiting corrosion of metals in aqueous systems.
Abstract:
A method is disclosed for producing an improved polyvinyl chloride plastisol or organosol coating composition having improved adhesion to glass, metal or fabrics. The composition is obtained by adding to the plastisol or organosol from 0.1 to 2 weight percent of a devolatilized product of hydrolysis of an aminofunctional organotrialkoxysilane of the formula (RO).sub.3 SiCH.sub.2 CH.sub.2 CH.sub.2 NH(CH.sub.2 CH.sub.2 NH).sub.x H wherein R is a monovalent alkyl radical of from 1 to 3 carbon atoms and x is zero or 1. The silane is hydrolyzed with at least 0.5 moles of water per mole of silane. The compositions are stabilized in respect to viscosity by including 0.5 to 1.1 mole per mole of primary amino group in the hydrolyzed silane product of a compatible carboxylic acid boiling above 150.degree. C. at atmospheric pressure.
