Abstract: A method of adhesively bonding a first component to a second component, which comprises a peripheral zone with which the first component is adhesively bonded in overlapping manner is provided.

Abstract: A method is provided for bonding shaped parts using a heat-curable adhesive by joining the parts with the adhesive and exposing the adhesive in the bonded joint thereby formed to electromagnetic radiation, at least part of the radiation being in the near infra-red. At least one of the parts is transparent to the electromagnetic radiation in the area of the bonded joint. This method is particularly suitable for producing vehicle lamp or headlight assemblies.

Abstract: Heat-vulcanizable adhesives for the bonding of solids, the adhesive contains polybutadiene or a polybutadiene mixture and/or copolymers of butadiene with ethylenically unsaturated monomers and other vulcanizable components, and at least 0.5% by weight (based on the weight of vulcanizable components) of a metal salt as a hardening catalyst. The adhesive is particularly useful in vehicle assembly. The adhesive in less than 5 hours exposure to air forms a protective skin which imparts washer resistance to the adhesive.

Abstract: Heat curable adhesives, based on polybutadiene containing hydroxyl groups, which have a content of (a) polybutadiene having a number average molecular weight of from about 1000 to 3500 and OH values in the range from about 20 to 100; (b) blocked multi-isocyanates, (c) sulfur and (d) conventional vulcanization accelerators, an which may also contain conventional, especially mineral, fillers, pigments and/or auxiliaries, show good elasticity behavior and high tensile shear strength after curing and have a relatively low viscosity favorable for processing before curing.

Abstract: Aminohydroxy fatty acid amides obtained by condensation from epoxidized fatty acid alkyl esters and polyfunctional aliphatic oligoamines may be employed as crosslinking agents for polyfunctional epoxide compounds used as adhesives and/or coating compositions.

Abstract: The invention relates to two-component polyurethane adhesive preparations in which the resin component is an oleochemical polyol. The oleochemical polyols used are ring-opened products of the reaction of epoxidized fatty alcohols, fatty acid esters (particularly triglycerides) or fatty acid amides with alcohols. The oleochemical polyols may be varied within wide limits in regard to their OH-functionality and so formulated with the hardener polyisocyanate components that the adhesives satisfy the relevant requirements. Reaction products of epoxidized triglycerides with monohydric alcohols are a particularly effective substitute for castor oil.

Abstract: This invention is directed to a process for preparing an adhesive, pre-gelled plastisol composition which comprises the steps of(a) mixing polyvinyl acetate or copolymers of vinyl acetate with one or more comonomers selected from the group consisting of vinyl alcohol C.sub.3 -C.sub.18 -carboxylic acid esters, ethylene, propylene, butylene, and vinyl chloride with conventional non-gelled plastisol mixtures based upon (i) polyvinyl chloride and/or polymethyl methacrylate and (ii) one or more suitable plasticizers in a ratio of from about 10 to 200 parts by weight of polyvinyl chloride or copolymers of vinyl acetate to 100 parts by weight of polyvinyl chloride and/or polymethyl methacrylate,(b) heating the mixture from step (a) to a temperature of from about 80.degree. to 130.degree. C.The resulting composition is useful in joining, sealing, or stiffening automobile body components.

Abstract: Process and compositions for producing bondings based on a two component adhesive system comprising1. an epoxide group-containing prepolymer obtained by reacting a polyether-urethane or a polyester-urethane which contains at least two terminal isocyanate groups with equivalent quantities of glycidol, and2. a primary amino group-containing polyether or polyamide having at least two primary amino groups, and a molecular weight between 200 and 1800.
