Barium Sulfate in Coatings

Barium Sulfate in Coatings

Barium sulfate is mainly used as a constitutional pigment in coatings,it significantly improves the various physical and chemical properties of the coating.

Improving physical properties: Barium sulfate can significantly increase the thickness, wear resistance, water resistance, and heat resistance of coatings
And the surface hardness makes the coating more durable and suitable for various harsh environments.

Chemical stability: Barium sulfate has high reflectivity, which can effectively protect the paint film from photo aging, thereby enhancing the durability and color stability of the coating. In addition, its low oil absorption and high filling characteristics help reduce coating costs.

Cost reduction: Barium sulfate can partially replace more expensive components such as titanium dioxide in coating manufacturing, thereby reducing production costs.

Specific application: Barium sulfate is widely used in latex paint due to its acid resistance, endowing latex paint with excellent acid resistance. In addition, ultrafine barium sulfate is used in the primer and topcoat
The application further optimized the workability and rheological properties of the coating.

Overall, barium sulfate plays an indispensable role in the coatings industry due to its unique physical and chemical properties, demonstrating its significant value and broad application prospects from improving basic performance to reducing costs.
