Abstract: The invention relates to an adhesive composition having an added component of rubber-epoxy such as XNBR-epoxy adducts. It was found that the new adhesive composition significantly reduces meander formation in the making of automotive parts.

Abstract: Structural adhesives are prepared from a chain extended elastomeric toughener that contains urethane and/or urea groups, and have terminal isocyanate groups that are capped with a phenol, a polyphenol or an aminophenol compound. The adhesives have very good storage stability and cure to form cured adhesives that have good lap shear and impact peel strengths.

Abstract: The invention relates to epoxy adhesives. An epoxy adhesive is provided that simultaneously has low E-modulus and high glass temperature. Such adhesives are useful in the manufacture of large machinery (e.g., automobiles), and are useful for bonding different materials, such as metal and carbon fiber composite. The cured epoxy adhesive can be formulated to have an E-modulus of less than 1000 MPa, and a glass transition temperature of at least 80 C. The epoxy adhesive comprises a capped polyurethane pre polymer, a core shell rubber, and polyetheramine-epoxy adduct.

Abstract: A structural adhesive exhibiting good humidity resistance in the uncured state, good failure mode after curing, good crash stability, and good corrosion resistance, is provided, as well as methods of use thereof. The structural adhesive and methods of use thereof are applicable, e.g., in complete knock down (CKD) assembly systems, e.g., in the assembly of automobile body structures.

Abstract: Structural adhesives containing a non-rubber-modified epoxy resin, an elastomeric toughener and a curing agent further include an epoxy-functional fatty acid oligomer and a polyol. The presence of the epoxy-functional fatty acid oligomer and a semi-crystalline or crystalline polyester polyol in combination increase the storage stability of the structural adhesive.
