Why choose our barium sulfate for car primer?

In the highly competitive automotive manufacturing industry, every detail determines the quality of the final product. Among them, the car primer, as the "first line of defense" for vehicle body protection and the "perfect foundation" for the topcoat, is of self-evident importance. The performance of the primer largely depends on its core functional filler - barium sulfate.
Today, we are going to uncover why our barium sulfate has become the "top choice" in the primer formulas of many car brands.

1. High Specific Surface Area & Optimized Particle Size Distribution - Achieving "Cost Reduction and Efficiency Improvement" from the Source
Have you ever been troubled by balancing the applicability, rheology and production cost of the primer?
Our barium sulfate has achieved a high specific surface area and an excellent particle size distribution through precise process control. This seemingly professional technical parameter brings you the direct benefits of:
Less binder demand: The high specific surface area means that our barium sulfate has a stronger interfacial interaction and can achieve the same filling and thickening effect with less dosage. You no longer need to invest too much in expensive resin adhesives.
Outstanding coating and rheological properties: The optimized particle size can effectively prevent sedimentation, making the coating system more stable. During construction, it can provide a smoother leveling experience, effectively avoiding defects such as orange peel and brush marks, and significantly enhancing construction efficiency.
In short: Use less, achieve better results, and cost less!

Second, achieve a perfect coating and lay a solid foundation for the car's appearance
The ultimate mission of the primer is to provide an impeccable base for the subsequent topcoat. Our barium sulfate is precisely produced for this purpose:
Achieve a smooth and densely structured perfect coating: Our product can effectively fill the micro-pores of the primer film, making the coating structure more compact and smooth. This is like a highly skilled mason, polishing an extremely smooth wall surface for the subsequent "finishing" (topcoat).
Enhance the overall coating performance: A dense coating not only looks smooth but also significantly improves the shielding protection (corrosion resistance, stone impact resistance) and mechanical strength of the coating, thereby extending the overall lifespan of the vehicle body's paint surface.
Final effect: A primer as smooth as silk is the starting point for stunning topcoats and long-lasting protection!
