An organosiloxane release coating composition useful for coating bakeware.

Bakeware release coating

A polyfluoroalkyl silicone having the general formula:

Polyfluoroalkyl siloxanes

Silicone pressure sensitive adhesive compositions are provided which are free of volatile organic solvents. Silicone fluids in the form of cyclic or linear organosiloxanes, and having a boiling point at atmospheric pressure of 250.degree. C. or less, are used in combination with an organopolysiloxane gum and an organosiloxane hydrolyzate of SiO.sub.2 units and triorganosiloxy units.

Silicone pressure sensitive adhesive compositions and method for making

An improved silicone composition is disclosed, which comprises:

Silicone compositions which exhibit enhanced cure characteristics

A method is provided for controlling the cure time of a platinum-catalyzed addition cured silicone foamable composition, comprising the step of adding to the composition an aqueous buffer solution having a pH of about 2 to about 10, wherein cure time is increased if the pH of the buffer solution is higher than the pH of the composition prior to the addition thereto of the buffer solution and decreased if the pH of the buffer solution is lower than the pH of the composition prior to the addition thereto of the buffer solution.

Method for controlling the cure rate of silicone foam

A silicone polymer substituted with both hydrolyzable leaving groups and epoxy groups is catalyzed with condensation cure catalyst and onium salt photoinitiator to produce a dual curable composition.

Dual curable silicone compositions

A moisture curable solventless organopolysiloxane composition is provided useful as an adherent construction sealant. Improved cure rate, higher elongation at break values and lower modulus RTVs are achieved by using a bis(ureido)silane as a coupler and an aminoxysiloxane as a crosslinker for a silanol-terminated polydiorganosiloxane base polymer.

RTV silicones having bis(ureido)silane chain extenders and aminoxy

Silicone foams are provided which have increased tensile strength as the result of using an effective amount of a silicone polyimide block copolymer having chemically combined organovinylsiloxy units in the silicone block.

High strength silicone foam, and methods for making

A method is provided for reducing the density of silicone foam from a platinum catalyzed foamable two-package mixture of vinyl organosiloxane, organohydrogen siloxane, and hydroxylated material. The platinum catalyst used in the foamable mixture is in the form of a mixture of a platinum vinyl siloxane and a platinum triarylphosphine. A platinum catalyst mixture of platinum vinylsiloxane and triarylphosphine also has been found effective.

Method for reducing silicone foam density and silicone foam compositions

N-Silylalkylamides are useful as adhesion promoters in room temperature vulcanizable compositions comprising polyalkyoxysilyl-terminated polydiorganosiloxanes. The formamides, which are preferred, are novel compounds.

Ketoxime compounds are added to foamable elastomeric silicone foam contain organic alcohol as a hydroxyl source to reduce foam density.

Low density silicon foam

N-Silylalkylamides are useful as adhesion promoters in room temperature vulcanizable compositions comprising polyalkoxysilyl-terminated polydiorganosiloxanes. The formamides, which are preferred, are novel compounds.
