Abstract: Compositions containing copolymers of epihalohydrins, an unsaturated epoxy comonomer, and optionally, ethylene oxide are readily cured to useful articles with peroxides when such compounds contain an acid acceptor. Covulcanizable compositions are prepared from mixtures of the epihalohydrin and epoxy copolymers with peroxy vulcanizable polymers.

Abstract: A novel process is provided for producing an improved electrode for an alkaline battery comprising the steps of adding an unsintered fluorocarbon resin powder to an active material powder and intimately mixing them together, applying a shear force to said mixture to thereby form agglomerates capable of retaining said active material powder in a network structure resulting from a fiber-formation of said fluorocarbon resin powder, adding an aqueous solution of a paste to said agglomerates, kneading them to mutually bind said agglomerates and thus forming a rubbery mass converting said rubbery mass into a sheet and attaching the sheet thus formed onto an electrically conductive core. The process provides an electrode having excellent reactivity and results in improved production efficiency.

Abstract: Improved three component insulating coatings for both wet solvent and dry electrostatic application to transformer wires contain an increased epoxy resin concentration and a decreased amount of polyvinyl acetal and phenol aldehyde resins. The increased epoxy content gives substantially improved coatings with no adverse dissipation and hydrolytic effects. The epoxy constituent can range from 30-60 percent by weight providing the ratio of the polyvinyl acetal to phenol aldehyde is kept within the range of from 1 to 1 to 2 to 1.

Abstract: This disclosure relates to a new self-locking threaded fastener means having a patch on the threaded portion thereof to provide self-locking properties. The patch may be comprised of a thermoplastic polymer such as a thermoplastic epoxy adhesive system and is applied to the threaded fastener in an unpolymerized state and is allowed to polymerize in situ. Since an unpolymerized adhesive composition would be applied as a liquid, it would not be necessary to heat the fastener, thus saving valuable energy as well as eliminating the chance of destroying any corrosion resistant coating on the fastener such as phosphate and oil. This new fastener means also has good multiple usage characteristics in that it may be installed and removed several times without losing its self-locking properties.

Abstract: An elastomeric composition comprising a fluoroelastomer, an epichlorohydrin elastomer, an acid-acceptor, a curing accelerator and a fluorine-containing polyhydroxy compound, which is handled without any difficulty and can afford, on crosslinking, a rubbery material excellent in physical and chemical properties at a wide range of temperatures.

Abstract: A primer coating containing, as the resin binder, a thermoplastic halogenated (at least partly fluorinated) ethylene polymer and a curable epoxy resin, and, as a filler pigment, finely-divided mica and metallic pigment powder, is disclosed herein. The primer coating gives fluoropolymer top coatings which have been simultaneously cured therewith unexpectedly high resistance to blistering and delamination when exposed to extreme conditions such as live steam under high pressure.

Abstract: An improved electrocoating composition is described for cathodic electrodepositions, which composition comprises a water-miscible mixture of a substituted conjugated diene polymer or copolymer of a specific general formula, with not more than 30 parts by weight for 100 part of said diene of an epoxy resin, a petroleum resin or mixtures thereof, the mixture being neutralized with an acid.
