Abstract: The invention relates to curing process wherein specific unsaturated diacyl-peroxides and/or unsaturated acylperoxycarbonates are used. These peroxides were found to be pre-eminently suited to the curing of silicone rubbers and polyester resins. Their use does not lead to blooming, bad smell and/or discoloration of the cured product, while allowing low residual monomer levels to be obtained at processing temperatures below the temperature used in conventional processes wherein peroxyesters are used.

Abstract: A polyisocyanate curing agent for laminate adhesive, comprising: (A) an isocyanate group-terminated prepolymer having isocyanurate group and urethane group, obtained by reacting an organic polyisocyanate containing at least (a1) an aromatic diisocyanate with an active hydrogen group-containing compound containing at least (a2) a diol compound having a number-average molecular weight of 100 to 2,000, and, as an optional component, (B) an isocyanate group-terminated prepolymer having urethane group, and, also as an optional component, (C) a silane coupling agent represented by the following general formula (1): OCN—(CH2)m—Si(OR)3  (1)  (wherein R is a methyl group or an ethyl group, and m is an integer of 1 to 5); and a process for producing the polyisocyanate curing agent. The polyisocyanate curing agent is usable in a laminate adhesive which can be aged in a short time without shortening the pot life, which has good adhesivity, and which can withstand a severe retort treatment.

Abstract: A tinting composition for tinting a surface which includes a solvent and a pigment selected from the group consisting of titanium dioxide, mica, and mixtures thereof.

Abstract: A silicone rubber based coating composition for air bags comprising about 0.1 to 50 wt % of spherical powder with an average particle size of about 10 &mgr;m to 300 &mgr;m.

Abstract: A liquid addition curing type silicone rubber composition comprising (A) an addition curing type organopolysiloxane component and (B) reinforcing silica fines having a specific surface area of 50-600 m2/g and surface treated with an organosilicon compound so as to bear 3-20% by weight of carbon on their surfaces prevents thickening after mixing and has an extended pot life.

Abstract: The present invention provides resin compositions comprising a thermoplastic resin, at least one phosphoramide having a glass transition point of at least about 0° C., preferably of at least about 10° C., and most preferably of at least about 20° C.; and at least one adjunct flame retardant. The present invention also relates to articles made from the resin compositions. The present invention also provides methods to make the resin compositions having improved heat properties over compositions known in the art.

Abstract: An organic silicon polymer is purified by washing at least once a solution of an organic silicon polymer with aqueous hydrochloric acid having a concentration of at least 0.001 N, and washing the solution at least twice with ultrapure water having a resistivity of at least 10 M.OMEGA./cm. Metal impurities can be removed from the organic silicon polymer to a sufficient level for use as electronic material without detracting from the polymer's own properties.
