1. Properties
Superfine precipitate barium sulfate has high reflectance in the wavelength range of 300 to 400 microns, which plays a vital role in improving thickness, wear resistance, water resistance, heat resistance, surface hardness and impact resistance of the coating film, also can protect the aging speed. It is an effective white functional filler that can also reduce the amount of titanium dioxide used in paints by 10% to 20%, regardless of coverage.
2. Application in Painting
2.1 Used as extender pigment
The specific gravity, whiteness, oil absorption, refractive index and particle sizes of superfine precipitated barium sulfate are close to TiO2’s, but much better dispersion and suitable particle size distribution range. Under normal circumstances, in order to make the titanium dioxide in coating can effectively play the covering performance, right amount of superfine precipitated barium sulfate will be added in. By this way, distances between titanium dioxide particles can be controlled to avoid flocculation, also reduce the amount of titanium dioxide without affecting the covering power.
2.2 Application in primer coat
The superfine precipitated barium sulfate has a relatively large surface area and good size of distribution range. Used in primer, just less binder can make better coating property and rheology. Smooth and dense coating can be obtained even more superfine precipitated barium sulfate be added to the automotive primer.
2.3 Application in primer coat
Superfine precipitated barium sulfate has characteristics of weather resistance, good gloss and small particle sizes. It can be used as an inert filler be added in primer coat to improve the fluidity, surface smoothness, hardness and keep the color’s stability. Even if the wall is exposed to the natural environment (such as light, humidity, etc.), it can play a long-term protection role.
2.4 Application in latex paint
Latex paint with superfine precipitated barium sulfate can improve its high gloss,mercerized texture, and prevent acid, which can play an anti-corrosion role for buildings exposed to the atmosphere in industrial areas.
2.5 Application in wood lacquer and decorative lacquer
Superfine precipitated barium sulfate has the characteristics of small particle size and low light absorption. It is also suitable for surface paints (wood lacquer), varnishes and natural lacquers.
It has good brightness, good leveling, strong light preservation performance, good compatibility with color material that superfine precipitated barium sulfate is best partner of paint.
