Coarse-pored microsilica matting agent 1000 mesh ultrafine silica powder coarse-pored microsilica is a white powdery inorganic chemical product, belonging to high-tech fine chemicals. The product is made from high-purity silica gel as raw material, processed and graded finely, with stable chemical properties and insoluble in water. Its purity is as high as 99.9%, with high whiteness, complete specifications and models. Used in coatings: it can significantly improve the weather resistance, corrosion resistance, scratch resistance, high-temperature resistance, and matting properties of coatings, and has excellent anti-settling properties.

Used in rubber products: it can improve multiple mechanical properties of the products, such as strength, tensile resistance, tear resistance, wear resistance, and corrosion resistance, significantly enhance the flexural resistance and aging resistance of rubber products, improve the bonding between rubber products and metal interfaces, and increase adhesion.

1. Used as an anti-caking agent and loosening agent for thermosetting powder coatings, as well as a special powder additive.

2. Used as a matting agent (flatting agent) for surface coatings, widely used in coatings, furniture paints, and artificial leather finishing agents (dosage is generally 3-5%).

3. Widely used as an anti-blocking agent for polypropylene, polyethylene, and other films.

4. Thickening agent for synthetic lubricants and silicone greases.

5. Lightweighting agent for newsprint.

6. Insulating and thermal insulation filler in the electronics and electrical industry.

7. Used as a lubricant (as an excipient in the pharmaceutical industry to improve particle flowability).

8. Commonly used in chemical experiments to separate or identify organic mixtures.
