Nepheline
Finex (Nepheline), nepheline syenite for powder filler processing products. Nepheline syenite is a natural mineral, free silicon, mainly combined by alkali feldspar and nepheline.
In the application, midalkalite mainly used to reinforcing the material performance , with below advantages:
Strengthening weather-resistance
improving the wear resistance, anti scratch, anti fouling, anti mildew and prevent chalking
To provide UV protection and prevent yellowing of the resin system
With low tinting strength, highlighting the best performance of the pigment
Having the similar refractive index of resin system, allowing high pigment loading in transparent or translucent coating applications
Good dispersibility and low oil absorption rate in the water based or oil based system, and low viscosity under high pigment loading
Highly stable chemical composition and pH
The ability of low vehicle demand and highly resistant to the frosting
