SIO2 Content: 28-30% NA2O content: 0.5% viscosiry: 10 PH value: 9.0-10.5 SP.GR: 1.19-1.21 Particle size(nm): 10-15 Characteristic: 1. Increase the elasticity of coating on the surface with wet strength, reduce or eliminate the surface dry too fast and the cause of crack, peeling of casting structure quality problems. 2. Excellent dehydration performance, easy to form a uniform drying coating. 3. Increase the adhesion of colloidal silica and refractory powder, bond strength and increase pulp and refractory aggregate coated with sex, increase the shell strength, reduce the coating and the shell thickness. 4. Improve the shell permeability. Volatilization roasting make polymer, form fine exhaust passage inside the shell, increase permeability, reduce casting defects such as misrun of thin water even. 5. Shell low residual strength. Polymer volatilization reduced shell, residual strength Yi Qing shell. 6. Low requirements for environment is conducive to the stability of the production process and quality. 7. Rapid drying, the drying time between the layers 1 ~ 2 h. 8. Water-based, environmentally friendly products. 9. Stable performance, long shelf life (1 year). Application: Precision casting Industry
