EpoxAcast® 670 HT (formerly 20-136) is an epoxy casting compound which offers high heat resistance up to 350° F/177° C if post cure schedule is used. EpoxAcast® 670 HT features a relatively low viscosity that ensures minimal bubble entrapment. EpoxAcast® 670 HT also offers an extra long working time of 3 hours.
Castings cure with negligible shrinkage and are very hard, very strong and heat resistant. EpoxAcast® 670 HT is ideal for making vacuum form molds, foundry patterns, forming dies & fixtures, hard rollers, industrial parts and high impact tools. EpoxAcast® 670 HT is also suitable for encapsulation applications or for use as a high temperature epoxy adhesive for bonding a variety of surfaces.
