Diatomite is a biogenic siliceous sedimentary rock, mainly composed of the remains of ancient diatoms. Its chemical composition is mainly SiO2, containing a small amount of Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5 and organic matter. The mineral composition of diatomite is mainly opal and its varieties, followed by clay minerals-hydromica, kaolinite and mineral debris. Mineral debris includes Shi Ying, feldspar, biotite and organic matter. The content of organic matter ranges from trace to over 30%. Diatomite is white, grayish white, gray and light grayish brown in color, and has fine, loose, light, porous, absorbent and permeable properties.
Diatomite coating additive products, with large porosity, strong absorption, chemical stability, abrasion resistance, heat
resistance and other characteristics, can provide excellent surface properties of coatings, compatibilization, thickening and adhesion. Because of its large pore volume, it can shorten the drying time. Can also reduce the amount of resin, reduce costs.

Main application
It is always used in latex paint, interior and exterior wall paint, alkyd resin paint, polyester paint and other coating systems,
especially in the production of architectural coatings.
In the application of coatings and paints, the surface gloss of the coating film can be evenly controlled, the abrasion resistance and scratch resistance of the coating film can be increased, moisture and deodorization can be eliminated, air can be purified, and the characteristics of sound insulation, waterproof, heat insulation and good permeability areachieved

Diatom mud is mainly composed of pure natural inorganic materials, is a green environmental protection material, itself without any pollution, no smell. Dialgae mud has natural environmental protection, manual technology, humidity regulation, air
purification, fire retardant, sound absorption and noise reduction, heat preservation and insulation, vision protection, wall
self-cleaning, long life and other characteristics and functions, is latex paint and wallpaper and other traditional decorative
materials can not be compared.
Diatomite coating additive products have the characteristics of large porosity, strong absorption, stable chemical properties,wear resistance and heat resistance.
