SINEPOXY® EPR-207 is a low-viscosity, high-boiling aliphatic diglycidyl ether that is fully
miscible with epoxy resins. It is non-volatile, non-toxic, and non-irritating, making it safe to handle during formulation and processing. The molecule contains flexible propylene glycol chains that impart significant elasticity and impact resistance to cured networks. When incorporated into epoxy systems, SINEPOXY® EPR-207 effectively reduces brittleness, improves resistance to thermal shock, and enhances overall toughness without compromising reactivity.
