摘要:
A laminate formed from a first fiber-reinforced ply joined by a laminating resin composition composition to a second fiber-reinforced ply. The laminating resin composition composition is the cured residue of a polyester resin being end-terminated with an alkyl acrylate group and diluted with less than about 35 wt-% styrene. The first fiber-reinforced ply is laminated to the second fiber-reinforced ply with the laminating resin composition by coating a surface of the first ply with an adhesive composition. The coated first ply surface is joined with a surface of the second ply and the adhesive cured. In making the laminating resin composition, unreacted alkyl acrylate can be reacted with an epoxy to push the reaction to completion.

摘要:
A thermosetting coating composition is prepared comprising an acrylic copolymer having pendent epoxide groups and hydroxide groups. The copolymer is prepared from 5 to 35 weight percent of a glycidyl ester of monoethylenically unsatured carboxylic acid, 5 to about 35 weight percent of hydroxy alkyl acrylate or methacrylate and 60 to about 90 weight percent of other monoethylenically unsaturated, monomers. This copoylmer is reacted with a dicarboxylic acid anhdride comprising at least about 50% by weight of an alkyl hexahydrophthalic anhydride. The amount of dicarboxylic acid anhydride present is such to provide between about 1.0 and 1.2 anhydride groups for each epoxide group on the acrylic copolymer. Amine-aldehyde crosslinking agent is present in the composition in amounts sufficient to provide at least 0.6 nitrogen crosslinking functional groups for each hydroxy group present on the acrylic copolymer. A solvent for the composition is likewise present.

A pneumatic tire comprising a textile cord reinforced rubber component is disclosed. The rubber component comprises a textile cord contacting a rubber composition. The rubber composition comprises: from 20 to 45 phr of a solution polymerized styrene-butadiene rubber having a bound styrene content ranging from 5 to 25 percent by weight, a vinyl-1,2 content ranging from 5 to 40 weight percent based on the butadiene content, and a Tg ranging from -85 to -50 °C; from 55 to 80 phr of a polyisoprene rubber selected from the group consisting of natural rubber and synthetic polyisoprene rubber; from 20 to 60 phr of a filler selected from carbon black, silica, and prehydrophobated silica; from 1 to 10 phr of a resin selected from the group consisting of carbamic resins, alkyl phenol formaldehyde resins, and phenol formaldehyde resins; and from 0.5 to 5 phr of a methylene donor.

The present invention relates to a water-soluble carbohydrate-polyamino acid-based pre-reacted binder composition,a method of its manufacture, use of the pre-reacted binder composition, a method of manufacturing a collection of matter bound by a polymeric binder, a binder solution or dispersion comprising the pre-reacted binder composition, as well as products comprising the pre-reacted binder composition in a cured state.
摘要:
Curable urea formaldehyde binder compositions are provided which are useful in coated abrasive and wood engineering applications, in a time released fashion. The time released curable binder compositions include a urea formaldehyde resin and an aryl phosphite in varying concentrations. The curable binder compositions of the present invention provide desirable working times and faster curing times under ambient or near ambient conditions.
