An epoxy-based crash durable adhesive composition including: (I) a liquid resin system comprising: (a) at least one epoxy resin; and (b) at least one toughener; wherein the viscosity of the above liquid resin system is less than about 800 Pa s at a temperature of 15&#xb0; C.; and wherein the viscosity of the above liquid resin system is greater than about 5 Pa-s at a temperature of 60&#xb0; C.; (II) a solid material comprising: (c) at least one hydrophobic fumed silica, wherein the fumed silica is present in the adhesive composition at a concentration of greater than 5 weight percent; and (III) a curative material comprising: (d) at least one latent heat-activated curing agent; wherein the rheology of the epoxy-based crash durable adhesive composition is such that the adhesive composition is pumpable at a temperature of 15&#xb0; C. or greater; and wherein the epoxy-based crash durable adhesive composition exhibits an increase in wash-off resistance; a process for making the above adhesive composition; and a process for bonding metal substrates together with the above adhesive composition.

Adhesive composition

One-component, moisture-curable polyurethane adhesives exhibit excellent handling strength before being fully cured, and excellent creep properties after curing. The adhesives include an isocyanate-terminated prepolymer made from polyols that include a crystalline polyester and hydroquinone bis (2-hydroxyethyl) ether, and a polyoxazolidine compound.

One-component hot melt polyurethane adhesive

The invention relates to a two-component adhesive based on hybrid urethane-acrylate epoxies comprising a core/shell rubber demonstrating good T-peel strength. The adhesives are suitable for use in industry, e.g., as adhesives for transportation industry applications.

Epoxy-acrylic hybrid adhesive

Aspects of the present invention provide a one component epoxy adhesive composition having improved impact resistance at low temperatures, such as &#x2212;40&#xb0; C. or less. In a first aspect, the adhesive includes one or more epoxy resins; at least one polyurethane based toughener; at least one amphipathic block copolymer; and one or more epoxy curing agents. In a further, aspect epoxy adhesive compositions having improved wash off resistance are also provided.

Crash durable epoxy adhesive compositions having improved low-temperature impact resistance and wash off resistance

Epoxy adhesive compositions contain a heat-activatable catalyst. The heat-activatable catalyst includes a tertiary amine catalyst and a novolac resin that has a weight average molecular weight of at least 3000. One-component epoxy adhesive formulations that contain the heat-activatable catalyst have unexpectedly good storage stability.

Storage-stable heat-activated tertiary amine catalysts for epoxy resins

The invention is an adhesive composition comprising: a) an isocyanate functional polyether base prepolymers having a z molecular weight average (Mz) of about 10,000 to about 80,000 g/mole; a carbon black having an average oil absorption number of at least about 80 to at most about 400 cubic centimeters of dibutyl phthalate per 100 grams of the carbon black; (c) reactive silicon in an amount from about 0.001% to about 10% by weight of the adhesive composition; and (d) one or more catalysts for the reaction of isocyanate with hydroxyl groups. The adhesive compositions of the invention surprisingly may have improved sag performance (i.e., decreased sag) when heated, while also making them more easily pumped.

The invention is a two part polymerizable composition comprising in one part an organoboron compound capable of forming free radical generating species and in the second part one or more compounds capable of free radical polymerization and from about 20 to about 30 parts by weight based on the weight of the second part of i) a halogenated polyolefin having halosulfonyl groups or ii) a mixture of a halogenated polyolefin and an organic sulfonyl halide. The second part may further contain a compound capable of causing the organoboron compound to form free radical generating species upon contacting the two parts. The first part may further comprise one or more compounds capable of free radical polymerization.
