Enhancing the competitiveness of aluminum profile coatings starts with choosing the right barium sulfate!

Introduction
In this article, our company's high-performance barium sulfate provides professional solutions for the specific requirements of aluminum profile powder coatings in terms of coating weather resistance, surface texture and cost optimization.

In the powder coating of aluminum profiles

1. Precise particle size control ensures the texture of the coating surface

Core advantages: Our company's flagship products have a narrow particle size distribution, and the D50 can be stably controlled within the specified range such as 0.4-0.5μm.
What problem to solve：Ensure that the gloss of the matte coating is uniform and consistent, and avoid the formation of light spots or cloud patterns. Significantly improve the surface flatness of the coating, reduce orange peel, and achieve a more delicate touch.

Second, extremely high purity ensures long-term weather resistance

Core advantages: Product purity ≥98%, strictly controlling the content of soluble impurities.

What problem to solve

Avoid coating powdering and yellowing caused by impurities in fillers from the root.

It endows the coating with excellent resistance to acids, alkalis and salt spray, making it suitable for harsh outdoor environments.

Three. Excellent optical and rheological properties

Core advantages: The product features high whiteness (≥95.5%) and low oil absorption (10-20g/100g).

What problem to solve

High whiteness: Ensure the color purity and vividness of white and light-colored coatings.

Low oil absorption: It helps improve the melt fluidity of powder coatings, facilitating processing and allowing for a higher filling amount to optimize formula costs.

Four. Excellent dispersibility and compatibility

Core advantages: The product has undergone special surface treatment and has good compatibility with resin systems such as polyester and epoxy.

What problem to solve

It is not prone to agglomeration during production and curing, effectively preventing defects such as particles and shrinkage cavities on the coating surface.

Enhance the stability of fillers in the system to make the physical and mechanical properties of the coating more uniform.

Summary and Application
Our company offers a complete range of barium sulfate products, which can provide professional choices for powder coatings of aluminum profiles with different gloss and performance requirements. They are widely used in building curtain walls, doors and Windows, home appliance shells and other fields.
