CB Series-Modified Ultrafine Precipitated Barium Sulfate

CB Series-Modified Ultrafine Precipitated Barium Sulfate is a high-performance product produced by Yunfu Hongzhi New Material Co., Ltd. by adopting Chufa's unique sulfuric acid process, which adopts silica-aluminum for surface modification, and it can be widely used in a variety of PCB inks, automotive paints, pigment pastes, industrial coatings and other fields, and it can significantly improve the surface gloss of the products, color rendering, antisinking, thixotropy, water resistance and reduce cost.

 

Ultra-fine particle size, good dispersibility

Compared with ordinary precipitated barium, CB series are characterized by small particle size, narrow distribution range, high whiteness, large specific surface area, good dispersibility (high shear dispersion is sufficient), acid and alkali resistance.

Anti-flocculation and anti-floating

We selected CB-300 from CB series and added it to red and blue paint systems respectively, and tested each performance, we can see that after silica-aluminum modification, CB series can help to improve the anti-sinking property of pigments, and provide excellent anti-flocculation stability and anti-floating and anti-floating properties.

Improve gloss and vividness

At the same time, CB series can also make the pigment dispersion more uniform, improve the color rendering effect of the pigment, and thus enhance the vividness, which indicates that replacing part of the pigment with CB series within the appropriate range will not only not affect the color consistency and transparency of the pure color pastes and paints, but also improve the color rendering of the color paints to a certain extent. It is generally recommended that the substitution amount is about 10% of the pigment amount, which can greatly reduce the cost of various paints.

In PCB ink, add 20-30% of the total amount of CB series, can reduce the adverse effects of the coating due to excessive baking, can enhance the skeleton, so that the paint film to maintain good flatness, to ensure that the processing of chemical gold and the stability of the development of the process, but also effectively improve the suspension and thixotropy.

 

 

 

Add total 10～20% modified ultrafine precipitated barium sulfate CB-300 as filler in automobile paint, the gloss of the paint film will not be reduced, and the gloss degree can still reach more than 100, and can reach the same gloss effect of varnish.

 

 

We also recommend CB series modified ultrafine precipitated barium sulfate for use in high-gloss, thin-coated powder coatings, plastic paints, household appliance paints, and other metal effect coatings, as well as anticorrosive coatings.
