Epoxy Curing Agents and Modifiers
Epodil 746 reactive diluent is an aliphatic glycidyl ether, specifically 2-ethylhexyl glycidyl ether (EHGE). The product is a monofunctional reactive diluent used to reduce the viscosity of epoxy resin systems. Since monofunctional diluents, in general, cause molecular weight chain termination, the minimum amount necessary to achieve the desired viscosity reduction should be used.
Epodil 746 reactive diluent is particularly useful where low volatility levels are required so that problems in poorly ventilated areas are minimized.
Category:Hardener
