The role of aluminum silicate in coatings
1. Ultra-fine aluminum silicate can replace a portion of titanium dioxide without affecting the dry film hiding power, while significantly improving the whiteness of the paint. When the amount of titanium dioxide remains constant, the hiding power of the paint is noticeably enhanced, and the overall whiteness is greatly improved, making the final product more visually appealing. 2. With a pH range of 9.7 to 10.8, ultra-fine aluminum silicate acts as a pH buffer. This is especially beneficial during the storage of vinyl acetate latex paints, where hydrolysis of the vinyl acetate can cause the pH to drop. By stabilizing the pH, it enhances the dispersion stability of the paint and prevents corrosion of the metal container's inner walls, ensuring longer shelf life and better performance. 3. The ultra-fine, grid-like structure of aluminum silicate helps to slightly increase the viscosity of the latex paint system. This improves the suspension properties, preventing sedimentation and reducing the formation of surface water or solid particles, which ensures a more uniform and stable paint application. 4. Incorporating ultra-fine aluminum silicate into latex paints enhances the durability of the paint film. It provides excellent scrub resistance, weather resistance, and also helps to reduce drying time, making the paint more efficient and long-lasting in both indoor and outdoor applications. 5. Due to its matting effect, ultra-fine aluminum silicate can be used as an economical matting agent in semi-gloss and matte finishes. However, it should not be used in clear varnishes, as it may interfere with the desired glossy appearance and clarity of the finish.
