Organopolysiloxane for use in release coating compositions are modified to control release values by substitution with phenolic compounds.

Silicone release coating compositions

Curable silicone caulk compositions are provided using a nonionically stabilized silanol-terminated polydiorganosiloxane, water, a silane cross-linker, a tin condensation catalyst, and calcium carbonate.

Curable silicone caulk compositions

UV curable epoxysilicone compositions are provided which can be used to impart improved release characteristics to plastic or paper substrates in an odor-free manner. Polyaryloniumhexafluorometalloid salts are used as photoinitiators. The UV curable compositions have condensed epoxyorganosiloxy units and haloarylalkylsiloxy units and have been found to be effective as control release agents when blended with epoxysiloxanes.

Substantially odor free, UV curable organopolysiloxane release coating

A method is provided for enhancing the controlled release characteristics of paper or plastic substrates by applying onto the substrate, a UV curable mixture of an epoxysilicone, an arylonium salt catalyst, such as a diaryliodoniumhexafluoroantimonate and a controlled release additive such as a phenolpropyl-substituted methyldisiloxane or an alkylphenol, such as dodecylphenol. The treated plastic or paper substrate is then subjected to UV irradiation to effect a tack-free cure of the UV curable mixture on the substrate.

Method for coating substrates with UV curable epoxysilicone compositions

Organopolysiloxane for use in release coating compositions arre modified to control release values by substitution with phenolic compounds.

Curable silicon caulking compositions are provided having improved shelf stability as a result of the use of a neopentyl orthosilicate.

Shelf stable silicone caulking materials

Certain bissilyl ureas have been found useful as adhesion promoters for silicone latex compositions. Self-bonding silicone elastomers are provided which exhibit enhanced adhesion to a variety of substrates.

Self-bonding silicone caulking compositions

Curable silicone caulking compositions are provided, employing an ionically polymerized silicone emulsion, a tetrafunctional organosilane, a tin condensation catalyst, calcium carbonate and tetramethylbutylguanidine, as a shelf stabilizer.
