ER4002 Flame Retardant epoxy Resin

In Stock

ER4002 is an ideal choice for automotive potting and encapsulation applications with an outstanding dielectric strength and flame retardant properties. It has a wide operating temperature range of -40°C to +150°C and good thermal conductivity.

Its low mixing viscosity gives it good flow characteristics allowing for potting units which have limited space with which to fill.
