An electrical component comprising an electrical component having an exterior protective layer on at least a portion of a surface. The layer is a cured copolymer of a reaction between at least one oligomer having a terminal ethylenically unsaturated group and at least one monomer having a terminal ethylenically unsaturated group. Alternatively, the layer is a cured copolymer of a reaction between at least two oligomers having a terminal ethylenically unsaturated group. The copolymerization reaction is preferably in the presence of a free radical initiator curing agent and a transition metal catalyst.

Exterior protective layer for an electrical component

A grease composition for use as a cable filling material which contains about 25 to 75 parts by weight of castor oil or a ricinoleate polyol, about 13 to 71 parts by weight of a hydroxy-terminated polymer of polymerized castor oil or the reaction product of a polyisocyanate compound and castor oil or a ricinoleate polyol, and about 4 to 12 parts by weight of colloidal particles such as silica, clay or mixtures thereof. Optionally, an antioxidant component can be added to impart high temperature resistance, a bleed inhibitor, typically of a rubber component, can be added to improve bleed resistance, a water blocking agent of a superabsorbent compound can be added to reduce water transmission, microspheres can be added to reduce the weight of the formulation, and/or conventional additives such as fungicides, bacteriocides etc. can be included. The invention also relates to an article of manufacture such as a cable having a sheath surrounding a plurality of optical fibers therein, with one of the grease compositions of the invention located therein.

Polypropylene compatible grease compositions for optical fiber cable

The invention generally relates to the protection of telecommunications and electrical devices, such as terminal blocks, with gelled oil compositions that employ aluminum complex soaps as gelling agents. The telecommunications devices are typically installed in an enclosure, filled with the gelled oil composition, to protect the device from moisture and corrosion. The gelled oils also include an oil component, a bleed inhibitor of polybutene, and optional amounts of antioxidant and pour point depressant.

Telecommunications articles containing gelled oil compositions

A grease composition for use as a cable filling material which contains about 75 to 95 parts by weight of a base component of a liquid or semi-solid polyol having a molecular weight of at least 4000 and a reduced amount of mono-unsaturated compounds, about 1 to 15 parts by weight of a thickening agent such as colloidal particles of silica, and between 1 and 5 parts by weight of an antioxidant. Optionally, a thermoplastic elastomer can be added to improve bleed resistance.

Cable grease composition and articles incorporating same

The invention generally relates to gelled oil compositions which employ aluminum complex soaps as gelling agents. The gelled oils comprise an oil component, a bleed inhibitor of polybutene, and optional amounts of antioxidant and pour point depressant. The gelled oils are particularly suited for use as buffer tube gels and as filling compounds for waveguides.

Gelled oil compositions

A grease composition for use as a cable filling material which contains about 75 to 95 parts by weight of a base component of a polyol or ester having a molecular weight of at least about 3000 and about 2 to 20 parts by weight of colloidal particles such as silica. Optionally, an antioxidant component can be added to impart high temperature resistance or a rubber component can be added to improve bleed resistance. Also, an article of manufacture of a cable having a sheath with one of the grease compositions of the invention located therein, and a method for filling the cable with such grease compositions.

High green strength curable urethane adhesive compositions of a polyol, an organic isocyanate compound, a thermoplastic polyurethane which is soluble in methyl ethyl ketone to at least 1 weight percent for imparting tack and green strength properties to the composition, and, optionally, a solvent for controlling the percent solids and viscosity of the composition.

Urethane adhesives

Polyurethane compositions comprising isocyanate cured specific equivalent weight hydroxyl bearing components used as potting compounds or sealants for hollow fiber or folded membrane biomedical separatory devices, especially when such devices contain containments such as glycerine or water.

Moisture and glycerine resistant polyurethane compositions for

Liquid, low viscosity, graft polyols comprising the liquid reaction product of a vegetable oil or unsaturated fatty carbon compound having at least eight carbon atoms, at least one hydroxyl group, and at least one double bond, said compound having other than terminal unsaturation a cyclopentadienyl compound and a terminally unsaturated monomer having at least one hydroxyl group, when cured with a polyisocyanate, melamine, or formaldehyde compound, or when esterified with a polybasic acid composition to form an alkyd resin, yield high solids or solventless polyurethane compositions useful as coatings, adhesives, potting or molding compounds.

Coatings utilizing graft polyols

Polyurethane compositions having improved adhesion comprising amine containing isocyante cured polyols of liquid esters of carboxylic acids having at least 8 carbon atoms for use as potting compounds or sealants for hollow fiber or folded membrane biomedical separatory devices, especially when such device contain contaminants such as glycerine or water.

Amine containing polyurethane compositions for separatory devices

High viscosity or solid resins containing hydroxyl groups can be modified by esterification with ricinoleic acid to yield polyols having much lower viscosity, improved solubility in non-polar solvents, higher equivalent weights and essentially the same hydroxyl functionality of the unmodified resin. These new polyols or their mixture with other polyols can be reacted with solventless polyisocyanates to yield polyurethane compositions useful as adhesives, potting or molding compounds. Alternatively, they can be diluted with a small amount of appropriate solvents and reacted with polyisocyanate, melamine or urea-formaldehyde resins, or used in the preparation of alkyd resins, yield high solids coatings useful in a variety of applications, such as plastics, business machine parts, metals, wood and building materials such as concrete, bricks, cinder blocks and the like.

Hydroxy acid esterified polyols

Polyol mixtures having about 10 to 60 weight percent of a ricinoleate compound and 90 to 40 weight percent of a C.sub.2 -C.sub.6 hydrocarbon polymer having at least one hydroxyl group. Polyurethane compositions comprising the reaction product of this polyol mixture with an organic isocyanate compound. These compositions may optionally include certain extender compounds. Also, a method for lowering the viscosity of C.sub.2 -C.sub.6 hydrocarbon polymer having at least one hydroxyl group by adding a ricinoleate compound thereto.

Ricinoleate modified hydrocarbon polyols

A plasticized polyurethane gel system comprising the reaction product of an isocyanate compound and a polyol in the presence of an ester plasticizer compound having a total solubility parameter of between about 8.3 and 8.9 or between about 9.1 and 9.7. Said polyurethane systems are cured, cross-linked, non-spewing, grease compatible, and reenterable. This extended polyurethane is further characterized as having superior insulating properties so that it can be used of repairing, encapsulating or reclaiming electrical or telecommunication cables as well as for hard volume encapsulants or general elastomer use.
