- Jul 28, 2020-

In terms of composition, resin sand is a mixture of resin, sand and curing agent, and clay sand is mainly a mixture of bentonite, water and sand; in terms of performance and use conditions-the cost of resin sand is much higher than that of clay sand, and resin sand is stronger than clay sand. Especially the high temperature strength; in terms of collapsibility, clay sand is better, but it does not mean that resin sand is much worse. In terms of recyclability, both can be recycled! But in terms of process, resin sand is better than clay sand, such as curing time, surface finish of materials, etc.
