Resin Selection

Usage Selection
When using adhesive, it is best to choose a resin with a moderate epoxy value (0.25-0.45), such as 6101.634; It is best to use a resin with a high epoxy value (greater than 0.40) when making castables, such as 618.6101; Generally, resins with low epoxy value (less than 0.25) are used as coatings, such as 601.604.607.609.
mechanical strength
Resins with high epoxy values have higher strength but are more brittle; The strength is good at high and low temperatures with moderate epoxy value; Those with low epoxy values have lower strength at high temperatures. Because the strength is related to the degree of crosslinking, the degree of crosslinking is also high after curing with high epoxy value, and the degree of crosslinking is also low after curing with low epoxy value, resulting in differences in strength.
Operational requirements
There is no need for high temperature resistance and there is not much demand for strength. We hope that the epoxy resin can dry quickly and not easily lose. We can choose a resin with a lower epoxy value; If you want good permeability and strength, you can choose a resin with a higher epoxy value.
