Application of diatomite coating additives in coating and paint industries

October 11 16:18 2021

Diatomite paint additive products have the characteristics of large porosity, strong absorption, stable chemical properties, wear resistance, heat resistance, etc., which can provide coatings with excellent surface properties, compatibilization, thickening and improving adhesion. Because of its large pore volume, it can shorten the drying time of the coating film. It can also reduce the amount of resin and reduce costs. This product is considered to be a high-efficiency matting powder product with a good cost performance. It has been used as a designated product by many large international coating manufacturers. It is widely used in latex paint, interior and exterior wall coatings, alkyd paint and polyester. Among various coating systems such as lacquer, it is especially suitable for the production of architectural coatings. In the application of coatings and paints, it can control the surface gloss of the coating film in a balanced manner, increase the abrasion resistance and scratch resistance of the coating film, dehumidify, deodorize, and also purify the air, sound insulation, waterproof and heat insulation, and permeability Good features.


Does not contain toxic chemicals

In recent years, many new indoor and outdoor coatings and decoration materials using diatomaceous earth as raw materials have been increasingly favored by consumers at home and abroad. In China, it is a natural material for potential development of diatomite indoor and outdoor coatings. It does not contain harmful chemicals. In addition to non-combustible, sound insulation, waterproof, light weight and heat insulation, it also has dehumidification, deodorization, and purification. Indoor air and other functions are excellent environmentally friendly indoor and outdoor decoration materials.

Can regulate indoor humidity

The research results of Kitami Institute of Technology in Japan show that indoor and outdoor coatings and decoration materials produced with diatomaceous earth will not emit harmful chemicals to the human body, but also improve the living environment.

First, the indoor humidity can be adjusted automatically. The main component of diatomaceous earth is silicic acid. The indoor and outdoor coatings and wall materials produced with it have the characteristics of ultra-fiber and porous. Its ultra-fine pores are 5000 to 6000 times more than that of charcoal. When the indoor humidity rises, the ultra-fine holes on the diatomaceous earth wall material can automatically absorb the moisture in the air and store it. If the moisture in the indoor air decreases and the humidity drops, the diatomaceous earth wall material can release the moisture stored in the ultra-fine pores.

Secondly, the diatomite wall material also has the function of eliminating odors and keeping the room clean. Research and experimental results show that diatomaceous earth can act as a deodorant. If titanium oxide is added to diatomite to make composite materials, it can eliminate odors and absorb and decompose harmful chemicals for a long time, and can keep indoor walls clean for a long time. Even if there are smokers in the home, the walls will not turn yellow.


Diatomite indoor and outdoor coatings and decoration materials can also absorb and decompose substances that cause human allergies, and have medical functions. The absorption and release of water by the diatomite wall material can produce a waterfall effect, decomposing water molecules into positive and negative ions. Groups of positive and negative ions float around in the air and have the ability to kill bacteria.
