SQG100 and SQG300 are a resin that is widely used as a self-hardening resin. it has the following properties.
1. As viscosity is low, it is easily mixed with sand and makes the flow of sand better.
2. SQG300HB is a environment-friendly resin that almost does not smell, so it can improve the working environment and reduce environmental pollution.
3. As strength is high, it can improve the quality of casting products.
4. The amount of usage is 0.8~1.2%.

- Catalyst acid value automatic controller (A+B Controller)
As a machine named A+B Controller that controls the acid value automatically according to the sand temperature change. it has the following advantages.
1. It can maintain stable stripping time.
2. It can conveniently control hardening speed.
3. It is convenient because only A, B two types of catalysts are used.
4. It can improve the quality of casting products by lowering S content in the reclaimed sand.
