Abstract:
Compositions of matter that have adhesion properties. The presence of a large number of silanols on the molecules described herein creates a solubility or dispersability of these molecules in aqueous solutions that is not obtainable from random hydrolysis of the precursor silanes.

Abstract:
Compositions of matter that have antimicrobial properties and adhesion properties and are highly dispersible in aqueous solutions. The presence of a large number of silanols on the molecules of this invention creates a solubility or disperseability of these molecules in aqueous solutions that is not obtainable from prior art antimicrobial monomers.
Abstract:
A method of encapsulating particulate materials that enables the particulate materials to be used in end use applications where they currently are not useful. The method uses specific sol gel technology to encapsulate solid particles. In addition, the method can be used to multiple coat a coated particle.
Abstract:
Improvements in the efficiency of heat pump systems including refrigeration units, heating and air conditioning systems and the like using a composition that is a pump oil comprising at least a compressor oil and, a material selected from the group consisting of an organic phosphate and mixtures of organic phosphates and, a hydxotreated heavy naphthenic distillate.
Abstract:
A deformable, abrasion-resistant coating is formulated from at least one multi-functional acrylate monomer, at least one aminofunctional silane, colloidal silica and at least one acrylate-terminated polyalkylene oxide. The acrylate-terminated polyalkylene oxide helps prevent gelling of the coating composition during stripping and also imparts the composition with deformability, without sacrificing abrasion resistance. Accordingly, the coating composition of the invention can be applied over and cured on an embossable substrate and the substrate can then be embossed, without causing the coating of the invention to crack or spall.
Abstract:
A primer composition, and a method for its use to improve adhesion between a silicone substrate and a subsequently applied paint film, is disclosed. The primer composition consists essentially of a mixture of an alkoxysilane, an organotitanate and a tin salt of a carboxylic acid, each component being present in a specific critical molar proportion.
Abstract:
This invention relates to silicone pressure-sensitive adhesives having improved viscosity stability and film physical property stability upon aging by a method comprising the condensation of a benzene-soluble resin copolymer of 0.6 to 0.9 triorganoxiloxy units per SiO.sub.4/2 unit which contains silicon-bonded hydroxyl radicals and a polydiorganosiloxane preferably containing silicon-bonded hydroxyl or other hydrolyzable endblocking radicals with a sufficient amount of an endblocking agent containing endblocking triorganosilyl units such as hexamethyldisilazane or trimethylmethoxysilane to result in a 1:0.8 to 1:3 mole ratio of silicon-bonded hydroxyl radicals and hydrolyzable endblocking radicals to total moles of triorganosilyl units provided by the endblocking agent. The condensation is conducted, when desirable, in the presence of a catalytic amount of a mild silanol condensation catalyst if one is not provided by endblocking agent and when, necessary, in the presence of an effective amount of an organic solvent such as xylene. Condensation is preferably conducted with heating under solvent reflux conditions.
