Description：
Kmeris ultrafine barium sulfate particles keep the crystal form of barite completely, and the product has the smallest average particle size (d50) of 1.5 μm, and the specific surface area, surface atomic number and surface energy are huge, thus making great changes in optical properties, adsorption, dispersibility and fluidity; completely surpassing the original excellent characteristics of barium sulfate and becoming a body pigment with excellent functions.
Advantages:
l It has good dispersibility and leveling property, and at the same time, as a carrier of pigment, it can make the pigment highly dispersed and make the coating obtain uniform color; High-purity whiteness makes the paint tone brighter and purer, and special crystal structure characteristics and high refractive index make the color richer and fuller.
l Excellent chemical inertness, better compatibility, easy to combine with other materials organically, and enhance the binding force; The suspension system is very stable and does not produce flocculation or precipitation.
l The strong surface energy of ultrafine barium sulfate makes the combination of paint film and substrate stronger; Uniform ultrafine particles make the paint film smoother and more durable.
l Ultra-fine barium sulfate with extremely low oil absorption can increase the critical material volume concentration of coatings and save more resin base materials. Therefore, it is more economical and reasonable to use Kmeris ultrafine barium sulfate.
