Low Viscosity Laminating System
With Very Long Potlife

Low viscosity epoxy resin system Epilox® M 730 + Epilox® - hardener M 903 is a laminating system with very long potlife. Larger batch sizes in areas with warmer climate are thus processable. The mix is warmed up to 50 °C until gelation has occurred. Post-curing is performed at ca 80 °C.

Curing schedule: Pre-heating of the resin/hardener mix to 50 °C, keeping 50 °C for 30 min, heating to 80 °C, keeping 80 °C for 1.5 - 2 h.

The system is preferably used for sewage renovation because it does not attack polyurethane films which cover the pipes.
