Abstract: The compositions and methods of the invention are related to RTV silicones having enhanced oil resistance. The compositions of the invention are useful for forming seals having oil resistance and desired tensile strengths after exposure to oil, including gear oil. The compositions are also useful for manufacturing articles sealed with the cured oil resistant RTV silicones.

Abstract: An adhesive composition applicator includes a housing having sidewalls and a neck that tapers to an opening. The housing encloses a gelled adhesive composition. The housing has a cross-sectional area and the opening has a cross-sectional area less than that of the housing cross-sectional area. A cap is provided that engages the housing. A mechanism is provided for urging the gelled composition material from the housing through the opening. The neck optionally also includes a shield to prevent gelled adhesive composition from running down the neck and provides a barrier against gelled adhesive smear reaching the point of intersection between the cap and the housing. To facilitate application of gelled composition to a point of application, a spatula is provided adjacent to the opening.

Abstract: A curable silicone composition is provided that includes a carboxylic acid scavenging reactant with an amount sufficient to reduce an odor associated with silicone curing. The carboxylic acid scavenging reactant illustratively includes a carbodiimide in the form of a monocarbodiimide or a polycarbodiimide; an aziridine; and a combination thereof. The composition optionally includes adjuvant provided to modify the physical or cure properties of the cured silicone. In particular, the composition is readily compatible with the inclusion of calcium carbonate, the use of which would otherwise cause gassing and/or curing upon storage. The composition optionally includes a condensation catalyst in the form of an organometallic compound with the metal ions of titanium, aluminum, tin, calcium, and zinc being particularly well suited for the function of catalyzing condensation reactions.

Abstract: A curable silicone composition is provided that includes a silanol functional silicone fluid. A crosslinker reactive with the silanol functional silicone fluid is combined with the silanol fluid to yield a capped reactive silanol fluid. The composition is provided with a propellant in an aerosol container under pressure so as to expel the capped reactive silanol fluid along with a diluent such as a nonvolatile unreactive silicone, an organic plasticizer, a volatile organic solvent, or a combination thereof. A film produced from this composition provides a plastic or rubber substrate with a high gloss finish with desirable wear properties. The inclusion of the optional diluent and the optional propellant facilitates aerosol application of the curable silicone composition as a thin film coating.

Abstract: An RTV seal forming silicone composition has a silicone base material that includes a lipophilic secondary phase insoluble in the silicone base material upon cure thereof. The resulting silicone has a shear adhesion strength as measured by transverse displacement of less than 50 pounds per square inch allowing for polymerized silicone removal without damage to an oil pan assembly.

Abstract: A topical composition has from 0.1 to 2 total weight percent of a first surfactant, an organic solvent, a polymer thickener, and 80 to 98 total weight percent water. The topical composition affords good topical cleaning or lotion actions and rapid water rinse in a form that has a suitable shelf life. The surfactant is chosen to yield a net HLB of between 7 and 13.

Abstract: A curable preform in an uncured state has a tensile strength of greater than one pound per square inch and a film shape of a disk, washer, U-shaped piece, strip, and polygon and is sized to engage a fastener head underside. The preform is composed of a curable liquid precursor having a polymer powder mixed therethrough. The preform is well suited to efficiently secure a fastener adhesively to an object.

Abstract: An article for delivery of a chemical reactant includes a liquid or solvated chemical reactant pre-moistened into an applicator. A chemical reactant impervious package has a pouch adapted to enclose the applicator for storage. The chemical reactant delivery article is based on capillary action to wick the continuing supply of chemical reactant to the substrate contacting portion of the applicator and as such is operative independent of chemical reactant gravitational flow.

Abstract: Compositions and methods for inhibiting corrosion of metallic surfaces are disclosed. The corrosion-inhibiting compositions are cost efficient, easy to use and can be conveniently removed or replaced. The corrosion-inhibiting compositions include a putty-like base material that is pliable and has sufficient tackiness to be securely affixed to surfaces. Corrosion inhibiting compounds are combined with the base material. These compositions provide a vapor phase corrosion inhibitor for both direct and indirect contact with metallic objects.

Abstract: A silicone composition that is oil resistant when cured is described. More particularly, this composition includes a silanol terminated silicone fluid, an organic plasticizer, a filler and a crosslinker, wherein the cured composition remains adhesive after exposure to oil. The present compositions provide superior adhesive properties after exposure to oil than conventional RTV silicone adhesives having M-stopped silicone plasticizers. Methods of making and using cured elastomeric products made from the present compositions are also provided.

Abstract: The present invention relates to improvements in the design and construction of apparatus for dispensing microwaveable hot melt adhesives and other heat sensitive materials. The apparatus comprises a dispenser which is heated by microwaves and then used to dispense a material therefrom. The dispenser is specifically designed to convert microwave energy into heat and to transfer the heat to the material to be dispensed in a more efficient and/or safe manner.

Abstract: A two-part RTV silicone preapplied compression gasket material for forming compression gaskets in place. The formulation includes a silanol terminated polyorganosiloxane, at least 5% by weight of the formulation of a tri- or tetra- methoxy or enoxy functional silane crosslinker, water, and, a condensation catalyst selected from the group consisting of stannous carboxylate compounds, dimethyl tin (IV) compounds and mixtures thereof. One of the two parts of the formulation includes the water component and the other of said two parts is a dry part and includes the crosslinker component.The formulation provides fast cure, fast development of compression set resistance and excellent ultimate compression set resistance.
