DESCRIPTION

Polygel 30 is a flexible unfilled epoxy resin system. It is transparent and cures at room temperature. Polygel 30 is very low in viscosity and normally does not require vacuum degassing to assure bubble-free casting and embedments. It may also be used in automated dispensing equipment.
