Abstract:
Compositions that cure rapidly to produce silicone foams and protective coatings are disclosed. These compositions comprise: (A) a certain liquid copolymeric polyorganosiloxane; and (B) an amino functional silicone polymer. For example, simple mixtures of the liquid copolymeric polyorganosiloxane and a polydiorganosiloxane having aminoalkyl substituents can be mixed together to form a resilient silicone foam. If the foam compositions are further provided with certain mineral fillers, a high degree of fire resistance is attained.
Abstract:
When a small amount of polytetrafluoroethylene powder is mixed with certain curable polydiorganosiloxane compositions containing a reinforcing silica and an organic peroxide curing agent and the resulting mixture is extruded and heat-cured, the resulting elastomeric article has a durometer of less than 30 and has a greatly reduced amount of porosity or bubbles.
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 siloxane polymer base that is useful as an excipient for many variable materials that can be compounded into it. Also disclosed are a method for the preparation of such bases, and another method regarding the preparation of the base and actives.

Abstract:
Compositions comprising siloxane polymers are disclosed. The compositions are useful as thixotropic bases for a variety of components, such as antimicrobial agents, sterilants, medicaments, antibiotics, analgesics, essential oils, preservatives, colorants, fragrances, and the like. Methods for preparing the compositions are also disclosed.
Abstract:
Compositions are disclosed that comprise at least one compound of formula IV: wherein the variable are as defined in the specification. The compositions are antimicrobial and optionally curable, and useful, inter alia, in dental, medical, and industrial applications for reinforcement and/or adhering two surfaces together.
Abstract:
Silicone compositions are disclosed which comprise a liquid silicone resin, a vinyl-containing silicone resin, a siloxane polymer, and a hydrosilylation catalyst. The compositions cure to give unusually strong, fuel resistant coatings and elastomers.
Abstract:
Hydrocarbon liquid resistant fluorosilicones are disclosed. The fluorosilicones comprise: (A) the reaction product of (i) a certain organosilicon resin consisting essentially of R.sub.3 SiO.sub.1/2 units and SiO.sub.4/2 units wherein R is a monovalent hydrocarbon radical, and (ii) a polyorganohydrogensiloxane; (B) a fluorosilicone containing vinyl radicals or hydroxyl radicals; and (C) a catalyst.
