Dull barium sulfate

Specifications

With the specific innovative physical matting method, Liangjiang-Brand- Extinction Barium sulfate provides a better choice for matting powder coating production, specially treated Liangjiang-Brand- Extinction Barium sulfate forms a perfect reflection angle in the coating film with its unique uniform crystal cube shape, and enough scattering provides a miraculous matting effect. It is totally different from common physical matting agent and normal barium sulfate.

It can be just used instead of original packing materials and without any specially designed formulas; stopping or reducing using matting agents can effectively reduce the cost. The particle size of Liangjiang-Brand- Extinction Barium sulfate and the film thickness are perfectly matched, and the matting effect is then well balanced with the smooth of film surface, resin never produces differences in the curing reaction ,and there is no worrying of over baking, so the matting effect is steady and outstanding.

The innovative physical matting method does not get the matting effect by producing uneven shrinking with differences of the curing rate, and naturally eliminates the shrinking tension on coating film surface which is critically harmful to the film adhesion, so the coating film gets a better impact resistance.

Liangjiang-Brand- Extinction Barium sulfate contains a 98.0% high purity of barium sulfate,it effectively increases the hardness of coating film and avoid the negative impact caused by the wax release on the surface of coating film-such as scratch,etc,and make the coating film more solid. Thanks for the fine chemical inertness and special ray absorbing function, the coating film has a fine weather ability and yellowing resistance, whether it is used indoor or outdoor, it can handle with ease.

Liangjiang brand ultrafine barium sulfate production process

Applications

Liangjiang brand-Dull barium sulfate, adopt domestic and overseas advanced process technology to make superfine processing via physical and chemical method. So that it has following charactors:

1. brighter color: Better dispersibility make it has higher covering power. At the same time, as carrier of pigments, it makes pigments dispersion enough to get uniform color and lustre; higher purity whiteness makes pigment more lighter; superfine crystal structuer and high refractive index makes color more abundent.

2. more stable system: Better chemical intertness of dull barium sulfate makes basic environment of every system keeping stable; superfine particles has better consistency, it can easily mixed with other oganic materials; homodisperse particles can stablely suspend in system, no flocculation and sediments.

3. firmer paint film: Its high density brings better abrasion performance; superfine particle can make paint film firmly conbined with substrate, homogeneous makes paint suface more smooth and more durable.

4. better weather fastness: Better chemical intertness of dull barium sulfate makes it waterproof and acidproof, it can resist acid rain, high temperature and corrosion; at the same time it also has spcial radial absorption function., increase paint’s weather fastness a lot.

5. used in paint and coatings--- it can be used as padding to instead precipitated barium sulfate, lithopone, titanium dioxide, active silicon dioxide, it can help to control paint’s viscosity, makes paints more lighter and more stable.

6. use in plastic industry – it can be used as padding in ABS materials, also can be used in jetton and mahjong, makes color ligher and also improve intensity, rigidity and wearproof.

7. used in rubber industry, the products of which particle size is lower than 400 mesh can be used as padding in rubber, it can reduce cost and improve rigidity, acid-base resistance property, water resisting property, it also can reinforce natural and synthetic rubber.

8. used in paper indutry --- super fine barite powder can be used as padding in white board, calendered paper to improve whitenss and surface coverage rate.
