Key Features & Benefits

Low Oil Absorption for Efficient Formulation Control

CF07 feldspar powder features a low oil absorption value, helping formulators reduce resin demand while maintaining stable viscosity. This improves formulation flexibility and enhances cost efficiency in coating systems.

Excellent Impact Resistance & Abrasion Resistance

Thanks to the inherent strength of feldspar minerals, CF07 feldspar powder significantly improves the mechanical durability of coating films, enhancing impact resistance and wear resistance in demanding environments.

Ideal Alternative to Silica Fillers

Unlike quartz-based fillers, CF07 feldspar powder is a feldspar mineral that does not carry the risk of excessive free crystalline silica exposure. It provides a safer and more compliant solution for modern industrial applications where health and regulatory concerns are critical.

High Dispersibility for Fast Processing

CF07 feldspar powder is engineered for excellent dispersion performance. It can be rapidly wetted and dispersed under high-speed mixing without the need for sand milling, enabling direct tank loading and filling. This greatly improves production efficiency.

Stable Mineral Structure & Wide Compatibility

With strong chemical inertness and stable mineral composition, CF07 feldspar powder is compatible with a wide range of resin systems, including solvent-based and high-solids coatings.
