Abstract:
A novel laundry detergent composition is disclosed comprising an organic surface active agent and an insoluble particulate material having an average particle size from 0.1 to 100 micrometers. The surface of the particulate material is modified by organosilicon compounds containing quaternary ammonium functional organic substituents. The presence of the strongly positive particulate in wash solution improves the cleaning power of conventional organic surface active agents.
Abstract:
What is disclosed are novel metal chelating agents which are bonded to inorganic substrates to immobilize them. An example of such a metal chelating agent is (CH.sub.3 O).sub.3 Si(CH.sub.2).sub.3 NH(CH.sub.2 CH.sub.2 NH).sub.2 (CH.sub.2).sub.3 Si(OCH.sub.3). An example of an inorganic substrate is a silica gel.
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 coolant solutions.
Abstract:
Adhesion of thermoplastic elastomers, such as unvulcanized styrene-butadiene rubber, to a solid substrate is obtained by using a primer containing a tackifier component, such as hydrogenated rosin or a coumarone-indene resin, and an amino-functional trihydrolyzable silane, partial condensates and hydrochloride salts thereof in which the amino-functionality is in the form of a primary or secondary amine.
Abstract:
The bond strength between solid inorganic materials, such as glass, and certain organic resins, such as epoxies, is strengthened by treatment of the solid with a mixture of a water soluble zirconyl salt and a gamma-trialkoxysilylpropylamine prior to the formation of the bond.
