A stabilized solution of hydrogen silsesquioxane resin is disclosed. The solution comprises 100 parts by weight solvent, 0.1 to 100 parts by weight hydrogen silsesquioxane resin, and 0.002 to 4 parts by weight acid. These solutions are useful for forming coatings on substrates.

Stabilization of hydrogen silsequioxane resin solutions

This invention relates to a low temperature method of converting coatings of hydrogen silsesquioxane resin or hydrolyzed or partially hydrolyzed R.sub.X Si(OR).sub.4-X to ceramic silica coatings. The method comprises applying a silica precursor coating to a substrate, exposing the coating to an environment comprising an amine and subjecting the coating to a temperature sufficient to yield the ceramic coating. The methods of the invention are particularly applicable to applying coatings on electronic devices.

Amine catalysts for the low temperature conversion of silica precursors

A group of substituted benzotriazoles unexpectedly improves the physical properties, particularly the tensile strength and tear strength, of peroxide cured organosiloxne elastomers.

Organosiloxane elastomers exhibiting improved physical properties

What is disclosed are organopolysiloxane release coatings which are curable on a substrate and which consist of a base siloxane copolymer containing CH.sub.3 SiO.sub.3/2 units; C.sub.6 H.sub.5 SiO.sub.3/2 units, C.sub.6 H.sub.5 (CH.sub.3)SiO units and (C.sub.6 H.sub.5).sub.2 SiO units; CH.sub.3 SiO.sub.3/2 ; a fluid polysiloxane, and a curing agent. They are especially useful on commercial and household cookware and bakeware.

Hard organopolysiloxane release coating

A release coating used in cooking and baking comprising a thermosettable polyorganosiloxane resin, a noncurable polydiorganosiloxane fluid, and a combination of at least two metal containing compounds. Optionally, the coatings may contain carboxylic acid.
