ER1426 Water White Epoxy Resin

In Stock

A two part epoxy resin designed for powder bonding and impregnation applications. Its a very low viscosity resin system ideal for use on complicated geometries or around components placed close together, while its long useable life makes it ideal for impregnation.

Its excellent clarity allows for visual inspection of the electronics and components through the resin while its high tensile strength provides good mechanical and physical protection.
