Abstract:
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.
Abstract:
Coatings comprising a latex particle comprising the reaction product of itaconic acid/anhydride and a monoalcohol, a monoepoxide, a monoamine or mixtures thereof are disclosed. Methods for using such coatings, particularly for inhibiting sound and/or vibration transmission through a substrate, are also disclosed.
Abstract:
Disclosed herein are 2K structural adhesive compositions comprising (a) a first component comprising (i) an epoxy-adduct formed as a reaction product of reactants comprising a first epoxy compound, a polyol, and an anhydride and/or a diacid; and (ii) a second epoxy compound; and (b) a second component that reacts with the first component. In one embodiment, the second component is an amine compound. These adhesives may be used to bond together substrate materials such as two half shells of wind turbine blades.
Abstract:
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 inorganic 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.
