Ultrafine Heavy Active Calcium Carbonate 1500 Mesh - Superfine Active Calcium Carbonate for Industrial Coatings

Application fields: This product is widely used in coatings, paints, sealants, plastics, rubber and daily chemical industries, serving as a crucial additive to enhance properties like durability, adhesion, color fastness, flexibility, mechanical strength, elasticity and product - related properties such as stability and viscosity, thus being suitable for various applications from protecting surfaces to making daily - use products of better quality.

Product Characteristics

Particle fineness and activity: With a fineness of 1500 mesh, its particle size is extremely fine, usually with a D50 particle size of around 5 μm and a D97 particle size of around 10 μm. After surface activation treatment, it has good lipophilicity and dispersibility. The active substances on the particle surface can improve its dispersion in organic media such as industrial coatings, enhance its affinity with resins, and enable it to be evenly distributed in the coating matrix.

High purity and whiteness: Generally, the calcium carbonate content is not less than 98%, and the impurity content is very low. It has high whiteness, usually reaching over 96%, which is beneficial for improving the hiding power, color purity, and decorative effect of industrial coatings.

Proper oil absorption value: The oil absorption value is generally in the range of 15 - 30 g/100 g. This oil absorption value allows it to absorb an appropriate amount of resin and additives in industrial coatings, which helps to adjust the viscosity, fluidity, and drying properties of coatings.

Good chemical stability: It has excellent chemical stability, is not easily affected by general chemical substances, and can maintain stable performance in different chemical environments, which is beneficial for the long - term storage and use of industrial coatings.

Functions in Industrial Coatings

Improving coating properties: It can increase the solid content of coatings, thereby increasing the thickness of the coating film. Its high hardness can significantly improve the wear - resistance of coatings, prolonging the service life of the coating. In addition, it can improve the hiding power, whiteness, gloss, and dispersion stability of coatings, enhance the weather - resistance of the coating film, enable it to maintain good performance under various harsh climatic conditions, and reduce the risk of hygroscopic deformation of the coating.

Adjusting coating processing performance: The 1500 - mesh ultrafine heavy active calcium carbonate has regular particle shapes and is easy to disperse in coatings, which can improve the leveling and construction performance of coatings, making them easier to brush, spray, or roll during construction, and improving work efficiency.

Product Advantages

Wide range of applications: It is suitable for various types of industrial coatings, such as anti - corrosion coatings, decorative coatings, and functional coatings, and can meet the performance requirements of different products in different fields.

Stable quality: With strict quality control, the physical and chemical properties of Ultrafine Heavy Active Calcium Carbonate 1500 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 the large - scale production and quality control of coating manufacturers.

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 reduce production costs and improve the market competitiveness of industrial coating products.
