Guibao Brand Heavy Calcium Carbonate 4000 Mesh - High-Density Calcium Carbonate for Advanced Coatings

Calcium carbonate is a non-toxic, tasteless, non-irritating white powder, one of the most versatile inorganic fillers. It is dry and does not contain crystallized water, and is exposed to the air.Almost insoluble in water, insoluble in alcohol, dilute acetic acid, dilute hydrochloric acid, dilute nitric acid to boil and dissolve;Heat is decomposed into calcium oxide and carbon dioxide.

Calcium carbonate has not only cheap, abundant resources, high grade, etc, but also has some properties of fllers, widely used in coatings, plastics, printing ink, putty, plastic flm, chemical fiber, sealants, adhesives, daily-used chemical industry, medicine, rubber, paper, toothpaste, cosmetics, food, textile, building materials, fodder, etc.

Product Characteristics

Extra - fine Particle Size: With a fineness of 4000 mesh, its particle size is extremely small, typically around 1 μm or less. Such fine particles can be uniformly dispersed in advanced coatings, filling the microscopic gaps in the coating film, which is beneficial for enhancing the smoothness and fineness of the coating film, and improving the surface quality of the coating.

High Purity: The calcium carbonate content is usually as high as 98% - 99% or more, with very low impurity content. High purity ensures that it has minimal impact on the color, stability, and other properties of advanced coatings, helping to maintain the high - quality performance of coating products.

Excellent Whiteness: It has a high whiteness, generally not less than 96%. The high - whiteness calcium carbonate can improve the whiteness and hiding power of advanced coatings, enhance their decorative and covering effects, and is especially suitable for the production of light - colored and white advanced coatings.

Low Oil Absorption Value: The oil absorption value is relatively low, usually in the range of 10 - 20 g / 100 g. The low oil absorption value helps to reduce the amount of resin and other additives in coatings, which can not only reduce production costs but also improve some properties of coatings, such as reducing viscosity and improving fluidity.

Good Chemical Stability: It has excellent chemical stability and is not easily affected by chemical substances. It can maintain stable performance in different chemical environments, which is beneficial for the long - term storage and use of advanced coatings and is not prone to chemical reactions that affect their quality.

Functions in Advanced Coatings

Improving Film - Forming Properties: As a filler, it can increase the thickness, hardness, and wear resistance of the coating film, enhance the adhesion of the coating to the substrate, and improve the physical and chemical properties of advanced coatings.

The extra - fine - particle - sized calcium carbonate can also improve the smoothness and gloss of the coating film, making the surface of the coating more delicate and beautiful.
Enhancing Color Performance: It can improve the whiteness and hiding power of advanced coatings, reduce the use of expensive pigments, and reduce production costs.

At the same time, it can also improve the color stability and uniformity of advanced coatings, making the colors more vivid and durable.

Improving Dispersion and Stability: The fine particle size of calcium carbonate helps to improve its dispersion in advanced coatings, making the coating system more stable and less prone to sedimentation. This is beneficial for maintaining the uniformity and consistency of advanced coatings during storage and use and improving the quality of the coating film.

Product Advantages

Wide Range of Applications: It is suitable for various types of advanced coatings, such as automotive coatings, industrial coatings, and high - performance architectural coatings.

It can meet the performance requirements of different coating products in different fields and is conducive to improving the overall performance of coatings.

Stable Quality: With strict quality control, the physical and chemical properties of Guibao Brand Heavy Calcium Carbonate 4000 Mesh are relatively stable.

This ensures the consistency of product performance during production, reduces product quality fluctuations caused by raw material differences, and is conducive to manufacturers' large - scale production and quality control.

Cost - Effective: While ensuring product performance, it has a relatively reasonable price. Compared with some high - performance fillers, it has a certain price advantage, which can help manufacturers improve the market competitiveness of advanced coating products.
