An adhesive composition comprising an epoxy compound and a compound comprising at least one aminimide functional group is disclosed. The compound comprising the at least one aminimide functional group is present in an amount from 2-8% by weight based on total weight of the adhesive composition and reacts with the epoxy compound upon activation by an external energy source. The adhesive composition also may comprise an amidine salt.

Structural adhesive compositions

Disclosed herein are compositions including (a) a first component comprising (1) an epoxy-adduct that is the reaction product of reactants comprising a first epoxy compound, a polyol, and an anhydride and/or a diacid and (2) a second epoxy compound; (b) rubber particles having a core/shell structure and/or graphenic carbon particles; and (c) a second component that chemically reacts with the first component at ambient or slightly thermal conditions. Also disclosed herein are compositions including (a) an epoxy-capped flexibilizer; (b) a heat-activated latent curing agent; and optionally (c) rubber particles having a core/shell structure and/or graphenic carbon particles; (d) an epoxy/CTBN adduct; and/or (e) an epoxy/dimer acid adduct. The heat-activated latent curing agent may include at least one reaction product of reactants including an epoxy compound and an amine and/or an alkaloid.

Disclosed herein are adhesive compositions comprising (a) a first component; (b) a second component that chemically reacts with said first component; and (c) graphenic carbon particles having an oxygen content of no more than 2 atomic weight percent. Disclosed herein are associated methods for forming the adhesive compositions and applying the adhesive compositions to a substrate to form a bonded substrate.

Adhesive compositions containing graphenic carbon particles

The present invention provides an aqueous polymer dispersion for vibration damping comprising a film-forming polymer in the form of dispersed particles comprising a polymer phase P1 and different polymer phases P2 and P3; the polymer dispersion obtained by free radical emulsion polymerization. Controlling the difference in glass transition temperatures of the polymers in the various polymer phases results in effective sound damping as determined by a Damping Loss Factor of at least 0.1 over a temperature range of at least 40&#xb0; C. determined at a frequency of 200 Hz over a temperature range of &#x2212;10 to 65&#xb0; C. Use of a chain transfer agent in the polymerization of the various monomer charges results in good appearance in the resultant vibration damping coating.

Aqueous vibration damping compositions

The present invention is directed to a coating composition comprising: (i) an aqueous dispersion of polymeric particles; (ii) a polyether carbamate compound; (iii) a filler material; and (iv) an microparticle; and wherein after application to a substrate and after curing, the cured coating composition demonstrates a composite damping Loss Factor of 0.05 or greater at a frequency ranging from 100 to 6,300 Hz and comprises a surface that is substantially free of defects.

Substantially defect-free sound and vibration damping coating

Disclosed herein are adhesive compositions comprising (a) a first component; (b) a second component that chemically reacts with said first component; and (c) graphenic carbon particles having a compressed density of 0.9 or less. Disclosed herein are associated methods for forming the adhesive compositions and applying the adhesive compositions to a substrate to form a bonded substrate.

Curable, one-package, stable adhesive compositions are provided comprising:

One component epoxy structural adhesive composition prepared from renewable resources

A coated article comprising (a) a substrate having two opposing surfaces; (b) a first curable film-forming composition applied to one surface of the substrate; and (c) a second curable film-forming composition applied to the opposing surface of the substrate, wherein the opposing surface is not coated with the first curable film-forming composition. Component (b) comprises a resinous binder; optionally, a curing agent and a metallic reflective pigment while component (c) comprises a polyepoxide; a thermoplastic polyester polymer; a curing agent a mineral filler; and microspheres.

Coated articles demonstrating heat reduction and noise reduction properties

A process is provided for applying multi-component composite coating compositions to substrates to provide sound damping and print-through resistance. The process includes applying at least one first coating composition to a surface of the substrate; applying at least one second coating composition over the first; and curing one or both of the first and second compositions, thereby forming a multi-layered coated substrate. The coating compositions may be applied by a method selected from spraying, extruding, brushing, and/or dipping.
