Epoxy resin selection

Choose from use

For adhesives, it is best to use a medium epoxy resin (0.25-0.45) resin, such as 6101.634; for castables, it is best to use a high epoxy resin (>0.40) resin, such as 618.6101; Low epoxy (<0.25) resin, such as 601.604.607.609.

Choose from mechanical strength

The resin with too high epoxy value is strong, but brittle; the strength is good at high and low temperatures with moderate epoxy values; the lower the epoxy value, the lower the strength at high temperatures. Because the strength is related to the degree of cross-linking, the epoxy value is high after curing, and the degree of crosslinking is also high. The epoxy value is low and the degree of crosslinking is low after curing, so that the difference in strength is caused.

Choose from operational requirements

No need for high temperature resistance, no requirement for strength. It is hoped that the epoxy resin can be dried quickly and not easily lost. The resin with lower epoxy value can be selected. If the permeability is good, the strength is better, and the epoxy value can be selected. Resin.
