ER2223

Epoxy Resin

ER2223 is a two-part filled, high Tg, low viscosity epoxy encapsulation resin which has primarily been developed

for encapsulation of electrical components that require high temperature resistance.

• Low viscosity; aids ease of potting difficult and complex geometries

• Good chemical resistance; offers good protection in a range of environments

• Excellent adhesion to a wide range of substrates

• Wide operating temperature range; excellent high temperature performance

Bulk Mixing When mixing, care must be taken to avoid the introduction of excessive amounts of air. Automatic mixing equipment is available which will not only mix both the resin and hardener accurately in the correct ratio but do this without introducing air. Containers of Part A (Resin) and Part B (Hardener) should be kept sealed at all times when not in use to prevent the ingress of moisture. Bulk material must be thoroughly mixed before use. Incomplete mixing will result in erratic or partial curing.
