Enhance the effect of oil-based anti-corrosion paint - Natural ultrafine barium sulfate

Metal corrosion is an "invisible killer" in the industrial field, causing economic losses of up to 3% of the global GDP each year due to corrosion. In the defense line against corrosion, anti-corrosion paint plays a key role, and natural ultrafine barium sulfate, as a functional filler, is becoming a core component in oil-based anti-corrosion paint with its unique physical and chemical properties.

High-density primary ore with uniform particle size - building a strong protective net
Natural ultrafine barium sulfate
This natural ultrafine barium sulfate from the primary mine in Guizhou, with outstanding parameters such as specific gravity 4.2, barium content 90-92%, and whiteness 86-89, injects stronger confidence into metal protection. Its particle size is relatively uniform. The high specific gravity characteristic enables the particles to stack more closely in the coating system, which can efficiently fill the pores of the paint film and form a "high-density labyrinth" penetration path.

The research "Discussion on the Anti-Corrosion Mechanism of Coatings" points out that "uniform particle size + high filling density" is the key to enhancing the shielding effect. When corrosive media such as moisture and oxygen attempt to penetrate, they need to repeatedly circle among the evenly distributed barium sulfate particles, significantly prolonging the penetration time. Experiments show that the oil-based anti-corrosion paint with this type of barium sulfate added still shows no signs of rust on the paint film after 24 hours of salt spray test (equivalent to one year in natural environment), making it particularly suitable for heavy-duty anti-corrosion scenarios such as Bridges and offshore platforms.

High purity, stability - durable and beautiful
The chemical purity of barium sulfate directly determines the long-term protective ability of oil-based anti-corrosion paint. This product contains 90-92% barium and only a trace amount of calcium carbonate. The high barium content means stronger chemical inertness, which can resist the erosion of acid and alkali media. Even when used in harsh environments such as chemical storage tanks and acid and alkali pipelines, it can ensure the long-term stability of the coating.
Meanwhile, the whiteness of 86-89 and the stable hue bring additional advantages to the anti-corrosion paint: it can meet the basic coating requirements of industrial equipment without the need to add too many toners, and can avoid the problem of "local yellowing" of the paint film during long-term use.
Xenon lamp aging test data shows that the oil-based paint with this type of barium sulfate added only has a 12% decrease in gloss after 1000 hours of exposure, and the color phase deviation is controlled within 0.5ΔE, truly balancing protection and aesthetics.

Low impurities and good dispersion - cost reduction and efficiency improvement
For the production and application of coatings, the dispersibility and impurity content of barium sulfate directly affect the process efficiency and cost.
Due to the mature purification process of primary ore, this product has few impurities and uniform particle size. In oil-based systems, it can avoid particle sedimentation and stratification without the need to add a large amount of dispersants, thus simplifying the production process.

From industrial plants to deep-sea platforms - Application prospects
From the steel frames of industrial plants to the platforms for deep-sea operations, this natural ultrafine barium sulfate, with its core advantages of "high specific gravity, high purity and stable performance", is becoming an "excellent partner" in oil-based anti-corrosion paints. It proves with parameters that a good functional filler can not only build an "invisible shield" for metal protection, but also create multiple values in terms of cost reduction, efficiency improvement and aesthetics.
