Abstract:
Physical properties, especially tack characteristics, of silicone adhesives comprising a silicone polymer and a silicone resin are improved by incorporation, prior to curing, of certain silicone cluster compounds. One preferred cluster compound has the formula RSi{OSi(OR').sub.3 }.sub.3 wherein R is a methyl group and R' is a secondary butyl group.
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 disperseability of these molecules in aqueous solutions that is not obtainable from random hydrolysis of the precursor silanes.
Abstract:
Compositions of matter that are antifreeze composition, coolants, heat transfer fluids, and de-icing fluids based on the use of coalescent efficient glycol ethers.
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:
A composition of matter that has surfactant properties in aqueous solutions. The presence of a large number of silanols on the molecules of these compositions creates a solubility or disperseability of these molecules in aqueous solutions that is not obtainable from the quaternary salt monomers. The compositions also have adhesive properties when cured with or without functional organic materials.
Abstract:
The present invention provides, inter alia, a colored flame candle. This colored flame candle contains: a wick, a body of solid combustible material surrounding the wick except a tip portion of the wick, and a first encapsulated color agent adapted to color a flame of the candle, which color agent is dispersed within the solid combustible material and/or on the wick. Also provided is a wick for a colored flame candle.
Abstract:
A novel cleaner and polish formulation that is eco friendly, that is, it is formulated without alcohols, organic solvents and without normal cleaning and polishing components, for example, amine functional materials, that are undesirable with regard to the environment.
Abstract:
The invention is a composition formed by the reaction product of (A) at least one polysiloxane selected from the group consisting of (i) R.sub.3 SiO(SiR.sub.2 O).sub.x SiR.sub.3 and (ii) ##STR1## where: has an average value of from 0 to 1000, z has a value of at least 3, R is independently selected from the group consisting of a hydroxyl group, alkoxy group, tri-fluoropropyl group, an alkyl chain of 1 to 4 carbon atoms, a phenyl group, and an amine functional group, with the proviso that at least one R on the polysiloxane is an amine functional group; and (B) at least one acrylate having the formula ##STR2## where R is H or CH.sub.3, n.gtoreq.1 and Q is an organic group.
Abstract:
The invention relates to a method of contacting two components to form a pressure-sensitive adhesive (PSA) construction, wherein the first component comprises a conventional PSA and an aminoxysilicon compound and the second component comprises the same PSA and an amidosilicon compound. The method provides improved adhesive bond strength over an unmodified PSA construction.
Abstract:
The invention relates to a method of contacting two components to form a pressure-sensitive adhesive (PSA) construction, wherein the first component comprises a conventional PSA and a liquid organohydrogenpolysiloxane and the second component comprises the same PSA and a cure agent for the liquid organohydrogenpolysiloxane. The method provides improved adhesive bond strength over the unmodified PSA, which bond strength generally increases with the passage of time.
