Abstract:
The invention provides a high weatherability pressure sensitive adhesive comprising an acrylic adhesive, a cross-linking agent and at least two different silane coupling agents. The weight ratio of the cross-link agent to the silane coupling agent is preferably about 0.1 to 0.4. The pressure sensitive adhesive can pass 500 hours weatherability test at conditions of 85° C./90% RH.

Abstract:
A method of forming a composition comprising adding at least one first compound that is at least one of an alkali metal salt, an ammonium salt, an alkali metal hydroxide, or an ammonium hydroxide and at least one second compound that is at least one of a Group IIA salt, a Group IIIA salt, a Group IIIB salt, a copper salt, a zinc salt, a cadmium salt, a manganese salt, an iron salt, a cobalt salt, or a nickel salt to a latex. This method allows for the formation of nanoparticles in the composition.
Abstract:
A rubber composition in which rolling resistance can be reduced without lowering wet grip performance, and a tire using the same can be provided. A rubber composition comprising 15 to 150 parts by weight of silica having a nitrogen adsorbing-specific surface area of 20 to 500 m2/g, on the basis of 100 parts by weight of a rubber component comprising not less than 15% by weight of a styrene-butadiene rubber (1) containing an styrene amount of not less than 33% by weight and a vinyl amount of not less than 30% by weight, and not less than 10% by weight of a styrene-butadiene rubber (2) containing a styrene amount of not more than 15% by weight and a vinyl amount of not more than 60% by weight, wherein a total amount of the styrene-butadiene rubber (1) and the styrene-butadiene rubber (2) is not less than 60% by weight.
Abstract:
A removable lacquer coating or paint of approximately 20 to 30% by weight of cellulose acetate butyrate, 50 to 80% by weight of alcohol and 10 to 30% by weight of diacetone alcohol is provided. It may also contain from 1 to 7% sucrose acetate isobutyrate. This removable paint can be removed by a formulation of diacetone alcohol, ethyl alcohol, hydroxypropylcellulose and a surfactant.
Abstract:
Stabilized polyethylene materials which offer an advantageously balanced combination of thermal, mechanical and processing properties, and which maintain their physical properties in chlorinated water environments are disclosed. The materials include an antioxidant system with components to provide extraction resistance in hot water environments and additionally provides oxidation resistance to both chlorine in the water interior of the pipe and oxygen in contact with the pipe's exterior.
Abstract:
This invention relates to a novel process which comprises feeding a mixture formed from diphenylethane and bromine to a stirrable reaction mass comprised of bromine and a bromination catalyst to yield a decabromodiphenylethane wet cake which can be most economically treated to provide a high quality decabromodiphenylethane product.
Abstract:
The invention relates to isomeric nonyl benzoates, processes for their preparation, mixtures of the same with alkyl phthalate, alkyl adipate, or alkyl cyclohexanedicarboxylate, and also to the use of these mixtures.
Abstract:
A synergistic flame retardant combination includes (a) a phosphorus salt having the formula wherein Md+ is a metal ion or an onium ion; d is 1, 2, 3, or 4 according to the identity of M and its oxidation state; each occurrence of R1 and R2 is independently C1-C18 hydrocarbyl; and each occurrence of m and n is independently 0 or 1; and (b) a phosphine compound selected from trihydrocarbylphosphines, trihydrocarbylphosphine oxides, and combinations thereof. Polymer compositions utilizing the flame retardant combination are described.
