ARALDITE® GY 285, alone or blended with epoxy resins based on bisphenol A or bisphenol A/F in combination with polyamine hardeners, is recommended for solvent-free coatings, impregnations, floorings, and trowelling compounds applied to steel and concrete substrates. Also, when combined with aromatic diamines, GY 285 is suitable for advanced composite applications manufactured through RTM filament winding. The reactivity of formulations based on ARALDITE® GY 285 is similar to that of unmodified bisphenol A epoxy resins. The chemical resistance of systems based on ARALDITE® GY 285 is comparable to that of liquid bisphenol A epoxy resins and significantly better than that of resins modified with reactive diluents. Under adverse storage conditions, ARALDITE® GY 285 may crystallize, but this can be reversed by heating the resin to 40°C while stirring. ARALDITE® GY 285 is miscible in all proportions with other epoxy resins, and the addition of at least 25% bisphenol A epoxy resin or epoxy phenol novolac will practically eliminate the tendency to crystallize. ARALDITE® GY 285 is sanctioned by FDA 175.300 CFR for contact with food.
