1. The phenolic resin for coated sand has good flowing property that is easy to coat sand.
2. Low free formaldehyde that reduce environment pollution and improve working condition.
3. High strength that not only improves the resin coated sand’s quality, but also reduce cost by adding less phenolic resin.
4. Low gas evolution is good to casting precision.
5. Can improve resin coated sand diffusion ability by
improving recipe to reach high temperature strength.
Considerations:
1、Use place should maintain good ventilation.
2、Must be maintained in a cool dry place, heat-proof,
anti-exposure, it is best to cold storage.
3、ZP204, ZP205, ZP206 guarantee period of up to 3 months.
4、Those who allergy to phenol and formaldehyde should be
protection.
