CCG is a product specially developed for coating aggregates, mainly suitable for sand casting process of cast steel, cast iron and other alloy materials. It is added as the main material to produce coatings that exhibit good suspension, good coating, high refractoriness, and good high temperature crack resistance.
| Specification | Refractoriness ℃ | Mesh number | Apparent density g/cm3 | linear coefficien expansion | pH value |
| CCG-1 | ≥1800 | 325 | 0.85 | ≤5.0×10-6/K | 7~8 |
| CCG-2 | ≥2000 | 325 | 0.90 | ≤4.8×10-6/K | 7~8 |
Product Features
1、Polygonal grain shape, strong adhesion;
2、Chemically stable, good resistance to excitation cold, stable and consistent crystal structure;
3、Thermal expansion coefficient（20-1000℃，≤4.8×10-6 /K）;
4、Higher modulus of elasticity than zirconium powder, higher decomposition temperature, lower creep at high temperature;
5、High refractoriness >1800℃, high load softening temperature;
6、The pH is weakly alkaline, PH value:7-8;
7、High resistance to slag corrosion and thermal shock;
8、Good flow and leveling properties;
9、Non-radioactive, healthier, more environmentally friendly.
