Inhibited tin or titanate catalysts are used in condensation cures of silicone materials. Such catalysts are command cure systems with long open pot life, yet have relatively fast cure when the cure mechanism is triggered. This combines the advantages of the inhibited addition cure systems (command cure) with the advantages of the condensation cure systems (lower cost).

Curable silicone compositions that cure through command catalysis

The invention is directed to joint assemblies comprising at least two adjacent panels and a jointing composition adhering to and positioned between the at least two adjacent panels, methods for installing joint assemblies, and jointing compositions. The jointing compositions include a sealant composition and a long chain ester in an amount of about 0.1% to about 15% by weight, based on the weight of the sealant composition in the jointing composition.

Joint assemblies, methods for installing joint assemblies, and jointing compositions

A sealant composition comprising a sealant, an adhesive resin, and a long chain ester, particularly dimerate and trimerate esters, is capable of unexpected adhesion to substrates such as ceramic substrates (e.g., concrete), glass substrates, metal substrates such as metal flat stock materials, polymeric substrates including substrates comprising natural and/or synthetic rubbers and substrates comprising thermoplastic polymeric materials, particularly for use in sealing around bathroom fixtures, in storage areas, vents, plumbing lines, flooring, wheel wells, and the like.

Adhesion promoters for sealants

The use of certain siloxane and silane materials for the conservation of organic and inorganic materials. More specifically, this invention deals with a method of impregnating organic and inorganic materials with siloxanes and silanes and ultimately curing such materials to provide preservation properties to such materials. An especially significant use of the method is to preserve and conserve ancient artifacts. The curable materials are represented by silanol containing polymers crosslinked with trialkoxysilanes.

Conservation of organic and inorganic materials

A method of preserving waterlogged materials and more specifically, preserving artifacts that have been submerged in water for long periods of time. A method of treating waterlogged materials that have been subjected to preservation techniques using polyethylene glycol as the preservative, and a method of restoring such materials from the deleterious effects of the glycol.

Method of conserving waterlogged materials

A composition comprising (A) at least one mercapto-functional organosilicon compound having an average of a least two mercapto groups per molecule and (B) a cure initiator. The mercapto-functional organosilicon compound may include mercapto-functional organosilanes, mercapto-functional organosiloxanes, and mercapto-functional copolymers. The compositions of the present invention polymerize or cure to form compositions comprising reaction products of components (A) and (B). The cure initiator is a metal salt that produces a uniform cure throughout the composition, regardless of the amount of oxygen present. The cured products range in properties from soft gels to though elastomers to hard resins and are useful as molded articles, electrical encapsulants, and sealants.

Compositions comprising mercapto-functional organosilicon compounds

Bubble formation observed when curing a sealant composition on a hot porous substrate is reduced where the room temperature vulcanizable silicone sealant composition comprises a polydiorganosiloxane, a crosslinker with silicon-bonded alkoxy groups, filler, and a titanium catalyst by the addition of 0.5 to 2 weight percent of an oximosilicon compound.

Method of reducing the bubble formation when curing a room temperature

A sealant made from a room temperature curing polydimethylsiloxane composition has a siloxaphobic surface layer at the air-sealant interface where this layer is a fluorocarbon compound and a drying oil oxidation product. Elastomeric compositions made from polydimethylsiloxanes having both low reactivity endgroups and high reactivity endgroups and a siloxaphobic agent of fluorocarbon alcohol or a reaction product of the fluorocarbon alcohol and a hydrolyzable silane, are particularly useful for sealing buildings because they can withstand the expansions and contractions. One siloxaphobic agent is the reaction product between a fluorocarbon alcohol and a methyltri(methylethylketoximo)silane and the formula of one of the reaction product compounds is ##STR1## wherein x has an average value of at least 6.
