A silicone composition is provided which comprises a vulcanizable adhesive formulation which comprises at least one oxygen-substituted allyl aromatic compound, a vinyl-containing polydiorganosiloxane, a hydrogen-containing polysiloxane, and a catalytic amount of a hydrosilylation catalyst. Further embodiments of the present invention include the oxygen-substituted allyl aromatic compound which provides adhesion to a substrate when present in a silicone composition and a method to provide cohesive failure to a silicone composition and a polyamide substrate.

Curable silicone adhesive compositions

A method for making a coated substrate, a system, and articles made thereby are provided wherein the coated substrate comprises a coating composition and a substrate. The coating composition comprises an alkenyl functional compound and a hydride functional compound, and the substrate comprises a catalytically effective amount of a platinum group metal catalyst having the formula Z Pt(0)L wherein L comprises an electron-withdrawing ester ligand, a quinone-based ligand, or combination thereof, y is in a range between about 1 and about 4, Z comprises a coordinating ligand, and x is in a range between 0 and about 3 wherein x&plus;y is in a range between about 2 and about 4.

Method for making coated substrates and articles made thereby

A silicone composition is provided which comprises a room-temperature vulcanizable adhesive formulation which comprises at least one bis(trialkoxysilylalkyl)succinate, a vinyl-containing polydiorganosiloxane, a hydrogen-containing polysiloxane, and a catalytic amount of a hydrosilylation catalyst.

Curable silicon adhesive compositions

The present invention relates to a method of introducing enhanced biofouling release properties to intact biofouling release coatings by exposing the surface of the biofouling release coating to a restorative compound for a time sufficient to effect enhancement of biofouling release properties. Also disclosed are kits useful in carrying out these processes.

Method for enhancing the properties of biofouling release coatings

A condensation curable coating composition comprises the following and any reaction product thereof: (A) a room temperature vulcanizable polyorganosiloxane composition; and (B) a marine foul release-enhancing proportion of at least one organic compatible silicone fluid free from silanol groups and being capable of blooming to the surface of a cured product of component A.

Curable silicone foul release coating and articles

A silicone composition is provided which comprises a room-temperature vulcanizable adhesive formulation which comprises bis(trialkoxysilylalkyl)hydromuconate.

Anti-fouling coatings comprise a room temperature vulcanizable polyorganosiloxane composition and a polyorganosiloxane free from silanol groups and comprising at least one hydroxy- or alkoxy-terminated polyoxyalkylenealkyl radical. The latter is capable of blooming to the surface of the cured room temperature vulcanizable composition, thus inhibiting the deposition of marine life on the coated article.

Sprayable, environmentally harmless addition curable silicone foul release coating compositions comprise a polyorganosiloxane having at least two organic radicals bound to silicon which have therein a carbon-carbon double bond, a polyorganosiloxane having at least two Si--H moieties per molecule, silica having a surface area in the range of about 100-600 m.sup.2 /g, a platinum group hydrosilylation catalyst and a polymerization inhibitor. One of the polyorganosiloxane components comprises internally functional and terminally functional compounds.

Sprayable, addition curable silicone foul release coatings and articles

Room temperature vulcanizable coating compositions, useful as anti-fouling coatings for marine structures such as ships, are prepared by a method comprising the steps of first blending a particulate reinforcing filler such as silica with a non-reactive polyorganosiloxane oil under high shear conditions, and subsequently combining the resulting masterbatch with at least one reactive polyorganosiloxane having a relatively low viscosity, a condensation catalyst and a crosslinking agent. The resulting compositions are sprayable in the absence of solvents, although solvents may be added if desired.

Addition-curable platinum group metal catalyzed silicone compositions are provided which utilize an adhesion promoter in the form of a Michael reaction product of a bis(aminoalkyl)tetraalkyldisiloxane, such as bis(aminopropyl)tetramethyldisiloxane, with an acryloxyorganotrialkoxysilane, for example, acryloxypropyltrimethoxysilane. The addition-curable silicone compositions can bond to plastic and metal substrates at temperatures of less than 100.degree. C. and in less than 1 hour, forming composites which fail cohesively upon separation.

Addition-curable silicone adhesive compositions

Silicon- and nitrogen-containing compositions prepared by the reaction of an aminoalkylsilane such as 3-aminopropyl- or 3-methylaminopropyltrimethoxysilane with a glycidoxyalkylsilane such as 3-glycidoxypropyltrimethoxysilane are useful as adhesion promoters in addition curable polyorganosiloxane compositions. The latter are illustrated by mixtures of vinyl-substituted polyorganosiloxanes and hydride polyorganosiloxanes, also containing at least one platinum group metal compound as a hydrosilylation catalyst.

Silicon- and nitrogen- containing adhesion promotors and compositions

Bis(bis-silylalkyl) dicarboxylates, especially maleates and fumarates, are prepared by a three-step process including esterification of malaic or fumaric acid or a functional derivative thereof with a branched dienol such as 1,6-heptadien-4-ol to form an alkadienol ester, reaction of the olefinic groups in said ester with a chlorosilane and alcoholysis of the chlorine atoms attached to silicon. The products are useful as adhesion promoters in addition curable polyorganosiloxane compositions.
