Resin ER12 – Hardener EH35 LV
Medium viscosity, unfilled, slow setting, epoxy casting and impregnation resin system for encapsulation of electrical and electronic equipment. It exhibits excellent flexibility, adhesion, superior corrosion resistance, high peel strength. Excellent for potting small electric transformers and coils, with minimum risk of cracking due to shrinkage.
ER12 is a standard epoxy resin used for many applications. It can be mixed with a variety of fillers, silica S1 or S15, calcium carbonate Kulu 2 or Kulu 15. This system complies with FDA 21 CFR 175.105 – adhesives and coatings.
