Polytec EP 660 - Unfilled Epoxy Adhesive

Bonding Technology

Polytec EP 660 is a 100% solid, two-component, low viscosity, high temperature and high Tg epoxy, impregnation and coating material.

Polytec EP 660 has an excellent chemical and moisture resistance and can withstand operating temperatures up to 300°C.

It is recommended as sealant and impregnation for all soaking surfaces like ceramics, woods, plastics, High-Temp fabric and powders as well as fiber bundles. A typical application is the impregnation and sealing of the magnesium oxide filler in tubular heaters/ heating elements.

The material can be applied via dispensing, jet-dispensing and manual application.
