There is provided a composition which vulcanizes at room temperature on exposure to moisture comprising a product resulting from mixing:

Self-bonding room temperature vulcanizable silicone compositions

There is provided a flame retardant composition comprising:

Silicone flame retardants for nylon

The adhesion of self-bonding, low modulus, one package, room temperature vulcanizable silicone compositions to a variety of substrates is effectively promoted by incorporation in the silicon composition, before curing, of a small effective amount of an adhesion promoting composition comprising at least one maleamidylalkyltrialkoxysilane or maleamidylalkyltriacyloxysilane compound of the formula: ##STR1## wherein A is divalent alkylene of from 2 to 6 carbon atoms and R.sup.1, R.sup.2 and R.sup.3 are, independently, C.sub.1 -C.sub.6 alkyl or C.sub.2 -C.sub.6 alkanoyl.

Composition for promoting adhesion of curable silicones to substrates

There are provided ultraviolet light absorbing agents of the following general formula ##STR1## wherein: ##STR2## Y is H or OH, Z is H, OH, OQ or OW, where at least one Z is OH if Y is H;

Ultraviolet light absorbing agents and compositions and articles

Platinum complexes of unsaturated siloxanes, substantially free of inhibitory compounds, provide superior hydrosilation catalysts when produced by heating a platinum compound with an unsaturated siloxane of the formula

Platinum complex catalysts

There are provided ultraviolet light absorbing agents of the formula ##STR1## wherein: X is &gt;C.dbd.O, or ##STR2## Y is H or OH; Z is H, OH, OQ or OW, where at least one Z is OH if Y is H;

Ultraviolet light absorbing compositions

There are provided ultraviolet light absorbing agents of the following general formula ##STR1## wherein: X is ##STR2## Y is H or OH, Z is H, OH, OQ or OW, where at least one Z is OH if Y is H;

Dye sensitized epoxy resins containing an iodonium salt cationic photoinitiator can be used in a variety of adhesive bonding applications. Using low intensity visible light, cure can be initiated after a short exposure of resin coated surfaces followed by clamping the subject pieces together for a time sufficient for a permanent bond to form.

Method of adhesive bonding using visible light cured epoxies

There are provided ultraviolet light absorbing agents of the formula ##STR1## wherein: ##STR2## Y is H or OH; Z is H, OH, OQ or OW, where at least one Z is OH if Y is H;

Platinum complexes of unsaturated siloxanes, substantially free of inorganic halogen and inhibitory compounds, provide superior hydrosilation catalysts when the unsaturated siloxane comprises, per gram-atom of platinum,

Platinum complex

A method of neutralizing a halogen silicone compound comprising adding to the halogen silicone compound an orthoformate and an alcohol so as to form an alkyl chloride and a formate which can then be distilled off.

Method of neutralizing a halogen silicone compound

A silyl phosphate which is an improved neutralizing agent for alkali metal hydroxides in silicone reactions, comprising the reaction product of a linear siloxane, and a phosphorous oxyhalogen or phosphoric acid. The reaction products of the phosphorous oxyhalogen over phosphoric acid are preferred. Such a reaction product is preferred for the continuous neutralization of alkali metal hydroxides in the equilibration of siloxanes.
