Epoxy Casting Resins

Epoxy casting resins under Sika's brand offer a good balance in between mechanical, chemical, thermal resistance, and easy processing due to low moisture sensitivity and low shrinkage.

Most of our epoxy casting resins are pre-filled with either mineral or aluminum powder which can reduce shrinkage and give higher hardness and strength to meet certain requirements of the application. Our epoxy casting resins are suitable for making both tooling and parts.
