Rotary wind wheels

The present invention is a window system for convertible motor vehicles that incorporates the use of woven fabric made from vinyl coated polyester yarn in such a way that it (1) reduces the 'greenhouse effect' that occurs when the soft-covering system is on the vehicle, whether the window is open or not (2) reduces the harmful unwanted effects the sun can have on the driver, the passengers and the interior of the passenger compartment, (3) reduces the airflow that occurs when the vehicle is driven with one or more flexible windows down, (4) makes it more difficult for a passerby to see into the passenger compartment, while still allowing an occupant to see the outside from inside the passenger compartment and (5) protects the flexible window from being scratched or otherwise damaged.

A solution comprising a composition and a volatile silicone solvent overcomes the environmental disadvantages associated with volatile organic compounds. The invention particularly provides for a primer composition for bonding silicone elastomers to metals that is free of volatile organic compounds comprises an epoxy alkoxy silane, a titanium ortho alcoholate or ortho ester, a silicon ortho alcoholate or ortho ester and a volatile silicone compound.

Fluorosilicone primer free of volatile organic compounds

A curable silicone pre-elastomer composition is disclosed comprising ammonium carboxylate, which upon cure yields a silicone elastomer having improved heat age properties and suitability for high or low temperature sealing applications.

Additive and method for enhancing the heat age properties of elastomers

The present invention relates to the use of a thin fluorosilicone elastomer coating as a cost effective solution to the oil weepage problem while retaining the sealing advantages of silicone rubber.

Fluorosilicone coatings

A composition is provided for treating silica filler in-situ, comprising a silanol-terminated, vinyl-containing polydiorganosiloxane having the general formula: ##STR1## wherein R is a monovalent substituted or unsubstituted hydrocarbon radical; R.sup.1 is R or a halogenated alkyl radical; R.sup.2 is R or a halogenated alkyl radical; 'a' is a number in the range of from about 1 to about 30; 'b' is a number in the range of from 0 to about 50; and 'c' is a number in the range of from 4 to about 30; the vinyl content of the polydiorganosiloxane being in the range of from about 1 to about 20% by weight and the silanol content being in the range of from about 0.1 to about 6% by weight. Preferably, R and R.sup.1 are methyl, R.sup.2 is methyl or 3,3,3-trifluoropropyl, and b is 0.

Vinyl-containing silanol-terminated silicone compositions for treatment

A heat cured fluorosilicone rubber exhibiting improved compression set comprises N,N'-meta-phenylenedimaleimide.

Heat cured fluorosilicone rubber compositions having improved

A polyfluoroalkyl silicone having the general formula:

Polyfluoroalkyl siloxanes

A composition for in situ treating silica filler is provided, comprising a silanol-terminated, vinyl-containing polydiorganosiloxane which functions both as a processing aid and as a crosslinking agent in vulcanizable fluorosilicone and silicone elastomer compositions.

Methyl- and phenyl-containing fluorosilicone terpolymeric fluids over the range of 30 cps to 200,000 cps are effective as additives for various uses. Over the range of 16,000 to 200,000 cps, the fluids are effective as additives in promoting a finger transferable self-bleed of lubricant in fluorosilicone-containing heat-curable rubber compositions, even after a post-bake of the composition. Over the viscosity range of 30 cps to 1000 cps, the fluids are useful in personal care and cosmetic products as water and oil repellency additives. Methods of ring opening polymerization are used to produce the terpolymeric fluids from cyclic reactants.
