摘要： An adhesion-reinforcing composition for an epoxy resin adhesive which comprises a copolymer resin particle having been ion-crosslinked with a univalent or divalent metal cation, which particle is comprised of (i) a core ingredient composed of a polymer comprising diene monomer units and optional crosslinking monomer units and having a glass transition temperature not higher than -30.degree. C. and (ii) a shell ingredient composed of a copolymer having a glass transition temperature of at least 70.degree. C. and comprising acrylate or methacrylate monomer units and 0.01-20 wt. parts, per 100 wt. parts of the shell ingredient, of units of a radically polymerizable unsaturated carboxylic acid monomer having a carboxyl group and 3-8 carbon atoms; the core/shell weight ratio being 5/1-1/4. A composition comprising 100 wt. parts of an epoxy resin, 15-60 wt. parts of the adhesion-reinforcing composition, and 3-30 wt, parts of a heat-activation type curing agent is useful as a structural adhesive for automobile parts.

摘要： An epoxy resin adhesive composition has excellent adhesive properties such as impact resistance, tensile shear strength and T-peel strength as well as excellent semi-gelling property. An epoxy resin adhesive composition comprising ionic crosslinking in a polymer utilized as the impact resistance modifier has not only excellent semi-gelling property and mechanical properties of cured products but also excellent storage stability for a long time and it is advantageously utilized when the application occasionally requires storage or standing of the material for one month to one year at the room temperature. The epoxy resin adhesive composition comprises an epoxy resin, a powder core/shell polymer and a heat activation type hardener for epoxy resins. The powder core/shell polymer is composed of a core comprising an acrylate polymer or a methacrylate polymer having a glass transition temperature of -30.degree. C. or lower and a shell comprising an acrylate polymer or a methacrylate polymer comprising crosslinking monomer units having a glass transition temperature of 70.degree. C. or higher and weight ratio of the core to the shell is in the range from 10/1 to 1/4.

摘要： The invention relates to a pressure sensitive sealant composition for sealing a clearance between a lamp unit housing and a vehicle body panel of an automotive vehicle. The pressure sensitive sealant composition includes (a) 10-40 wt % of a component A that is at least one copolymer selected from the group consisting of hydrogenated styrene-butadiene copolymers, hydrogenated styrene-isoprene copolymers, and modified copolymers thereof; (b) a component B that is at least one tackifier selected from the group consisting of petroleum resins, terpene resins, rosin resins, coumarone-indene resins, hydrogenated resins thereof, and modified resins thereof, and (c) a component C that is a hydrocarbonic plasticizer. The pressure sensitive sealant composition is prepared by maxing together 100 parts by weight of the component A, 20-60 parts by weight of said component B, and 150-400 parts by weight of said component C. In order to apply the pressure sensitive sealant composition for the purpose of saealing, the pressure sensitive sealant composition is heated end directly applied in the state of a bead onto a member to be sealed, or otherwise applied to the member after it has been formed into the bead state.
