Application: Furan resin for foundry is widely applied to steel casting, iron
casting, ball iron and high-grade sand moulding;alloy casting
and nonferrous-metal casting. This resin is strong in extension
strength with smell, and send out low volume of gas, and
thus the size of cast to be in high accuracy and fine in quality.

There are two kinds of resins:solidified resin at constant temperature(self-hardening resin) and hot box resin.
