It could be a long shot, but when doing experiments with various epoxy-amine reactions, I’ve noticed that if you were to mix an excessive amount of resin (DGEBA) and small amounts of polyetheramine hardener (something that is called amine adduct preparation) and leave it for 6 months sealed under nitrogen blanket, then it will turn from clear liquid to amber liquid. Reinforced with glass flakes, Seaguard® FF is both impact and abrasion resistant, resists sea water, mineral oils, aliphatic hydrocarbons, and splashes from petrochemicals. 63. A method for radically improving the processing and performance properties of To deal with these challenges, we developed adducts as latent accelerators for one-pot epoxy/dicyandiamide system through the addition reaction of epoxy, phthalic anhydride Hempadur 85671 is an amine adduct cured, phenolic epoxy (novolac) coating with very good adhesion and excellent chemical and high temperature resistance.

Epoxy coatings are formulated based upon the . Waterborne Amine Epoxy is formulated to provide good chemical, When diethanolamine (DEA) is used as a curative for a DGEBA epoxy, a rapid “adduct-forming” reaction of epoxide with the secondary amine of DEA is followed by a slow “gelation” reaction of epoxide with hydroxyl and with other epoxide. Can be applied in occupied facilities. The low modulus one-component heat curable epoxy compositions are desirable for this application. 3) When choosing a formulated amine adduct, it is important to discuss the chemistry/formulation and performance expectations with the curative supplier, (as aided by accelerators), will improve blush resistance of an amine-epoxy formulation.
