Longsheng Group Ultra-Fine Light Calcium Carbonate 200 Mesh - High-Performance Calcium Carbonate for Coatings
Features: non-toxic, odorless, non-irritating, fine particles, rough surface, large specific surface area, high oil absorption value.
Application fields: widely used in paper, plastic, plastic film, rubber, daily chemical, chemical fiber, adhesive, sealant, building materials, paint, paint, ink, putty, linoleum, sealing wax, putty, medicine, food, food, etc.
Waterborne coating industry
The application in the water-based coating industry is more widely used, which can make the coating non-settlement, easy dispersion, good gloss and other characteristics. The dosage of water-based coating is 20-60%.
Paper industry
Calcium carbonate plays an important role in the paper industry to ensure the strength, whiteness and low cost of paper.
Cable industry
It can play a certain insulating role in the cable industry. It can also be used as a friction agent for toothpaste.
Product Characteristics
Particle Size and Shape: With a fineness of 200 mesh, its average particle size is relatively coarse compared to some ultra - fine calcium carbonates, but it still has good dispersibility in coatings. The particle shape is relatively regular, which helps to improve the filling effect and film - forming properties of coatings.
High Purity: The calcium carbonate content is usually high, generally not less than 95%, and the impurity content is extremely low. This high - purity characteristic ensures that it has little impact on the color, stability, and other properties of coatings, and can maintain the original performance of coatings.
Good Whiteness: It has excellent whiteness, usually reaching over 90%. The high - whiteness ultra - fine light calcium carbonate can enhance the hiding power and decorative effect of coatings, making the coating film look more delicate and clean.
Proper Oil Absorption Value: The oil absorption value is moderate, generally in the range of 30 - 40 g / 100 g. This oil absorption value is beneficial for the formulation design of coatings. It can absorb an appropriate amount of resin and additives, helping to improve the fluidity, drying properties, and film - forming properties of coatings.
Good Chemical Stability: It has excellent chemical stability and is not easily affected by general chemical substances. It can maintain stable performance in different chemical environments, which is beneficial for the long - term storage and use of coatings and is not prone to chemical reactions that affect quality.
Functions in Coatings
Filling and Thickening: As a filler, it can increase the thickness and volume of the coating film, improve the filling performance of the coating, and make the coating film more compact. It can fill the pores and uneven surfaces of the substrate, improve the flatness of the coating film, and enhance the decorative effect.
Improving Hiding Power and Color Performance: The high - whiteness and proper particle size of ultra - fine light calcium carbonate can improve the hiding power of coatings, covering the color and texture of the substrate. At the same time, it can also improve the color stability and uniformity of coatings, making the colors more vivid and durable. In some light - colored or white coatings, it can be used as a main pigment extender to reduce the use of expensive pigments and thus reduce production costs.
Enhancing Film - Forming Properties and Physical Properties: It can improve the adhesion, hardness, and wear resistance of the coating film.
The appropriate particle size and shape can help the resin form a more dense and uniform film - forming structure, improve the mechanical properties of the coating film, and make it more resistant to scratching, abrasion, and impact. In addition, it can also improve the weather resistance and corrosion resistance of coatings to a certain extent, prolonging the service life of coatings.
Product Advantages
Wide Range of Applications: It is suitable for various types of coatings, including architectural coatings, industrial coatings, wood coatings, and so on. It can meet the performance requirements of different coatings in different fields and is conducive to improving the overall quality of coatings.
Stable Quality: With strict quality control, the physical and chemical properties of Longsheng Group Ultra - Fine Light Calcium Carbonate 200 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 reduce production costs and improve the market competitiveness of coating products.
