Paint and Coatings
Share |

The annual production of paints and coatings in the United States alone is around 1.3 billion gallons. Each paint is designed with specific attributes in mind, and silica is one of the ingredients that allows for each specificity. Silica functions in paints and coatings as a great low-cost extender. As in other applications, silica is desirable for its chemical inertness which allows for good acid, chemical, and heat resistance. Along with its chemical inertness silica's hardness improves abrasion resistance in paints.

Paint formulators select micron-sized industrial sands to improve the appearance and durability of architectural and industrial paint and coatings. In architectural paints, silica fillers improve tint retention durability, and resistance to dirt, mildew, cracking and weathering. Silica‚Äôs low oil absorption allows increased pigment loading for improved finish color. In marine and maintenance coatings, the durability of silica imparts excellent abrasion and corrosion resistance. 

 Additionally, silica improves the most important qualities in paints such as reflectance, brightness and color consistency for any large scale uses. Industrial sand therefore plays a role in keeping the buildings, cars, and boats we see from looking worn or dingy.
