4 Reasons Why Diatomaceous Earth is Perfect for Paint & Coating


A great solution for just about everything, diatomaceous earth (DE) is a siliceous sedimentary rock (white to off-white powder) that can be milled and processed to be used in an assortment of ways. It’s become popular in various industries for many different reasons, from food grade versions that improve digestion, as an ingredient that protects pets from flees, to DE filtration, acting as a water filter, separating microorganisms and solids. With all these capabilities, what makes it so great for the paint and coatings sector, which is known to be one of the most regulated industries in the world?

1. High Quality

Diatomaceous earth resists cracking and therefore, provides a smoother look. Celatom Brights diatomaceous earth products for example, have great opacity and flatting with less porosity, making it more stain resistant. Celatom Brights also has a lower density, which creates better performance using less additives.

2. Consistency

Diatomaceous earth acts as a multi-functional mineral additive that improves paint and coating performance. It provides a polish, gloss, and sheen control, yet also helps to maintain open and release times for solvents. DE even has a consistent viscosity, touch-up performance, and shelf stability that helps create a more dependable product customers can rely on. This results in less quality control issues.

3. Reduces Costs

Diatomaceous earth paint additive products require less resin, which decreases costs. Coatings with DE also have reduced drying time due to its larger hole size, saving time and money.

4. Generally Safe

Diatomaceous earth is made of mostly amorphous silica, which has low toxicity and little to no crystalline silica, a natural material found in sand, soil, and stone. Silica dust can be hazardous when inhaled and fatal to the lungs. The amount of crystalline silica or lack thereof varies depending on the DE purchased.

These reasons are important to considering diatomaceous earth as a filler or additive to improving the performance of paint and coatings. This naturally occurring product has a variety of uses in this industry as well, often used for interior and exterior paints, as well as decoration material use, and more.
