Lapox® AH-667 by Atul is a viscous liquid aromatic amine hardener having 60% 4,4’-diaminodiphenyl methane and 40% oligomers. It is available in brown viscous liquid at room temperature. It can be made more flowable by heating at 70°C to 80°C. Basic liquid epoxy resin (EEW:190) cured with stoichiometric ratio of Lapox® AH-667 provides glass transition temperature (Tg) over 160°C along with excellent combination of mechanical, electrical and thermal properties. Exhibits excellent electrical insulation properties and high chemical resistance. Suitable for processing by filament winding, pultrusion, lamination and castings. Lapox® AH-667 is recommended for prepreg, electrical components, general engineering components and structural composites. It has a shelf life of one year.
