As a high-precision innovative function filler of nanometer-class, BSM-MA is specially developed for electronic printing ink and writing ink industry.
The use of complete and uniform film coating technology enables it to have highly efficient pigment dispersibility and to fully retain each pigment crystal grain around it and well distribute in resin and solvent so that the intrinsic hiding power and optical performance of each pigment crystal grain may be maximized to exhibit a purer color image and vividness.
BSM-MA further reduces its oil absorption by complete film coating treatment, thereby reducing the resign and solvent consumption in formulas. As a result, a better quick drying property is achieved and volatility be reduced.
Another important application of BSM is its role as a pigment dispersant in color masterbatch. It is well-known that most pigments for plastic are expensive. Hence how to improve the covering power of pigment is a concern of color masterbatch manufacturers. The wave length, color and amount of the light absorbed, reflected and scattered by varied pigments are different. The area of pigment that can be used for scattered light determines the service efficiency of color. Almost all pigments have conglomeration or flocculation in applications more of less and the service efficiency of pigment will be attenuated due to the reduction in the scattering area. Research and practice show that BSM may facilitate the dispersion of pigment during the manufacture of color masterbatch, and the addition of BSM does affect the color tone of the pigment in products thanks to the fact that the light refraction factor of BSM is similar to common polymers. Repeated applications and practices indicate that pigment consumption in color masterbatch grains may be reduced by 10%. In addition, the X-ray non-transparency of BSM allows it to be used for the manufacture of the raw materials of toys for children (easy to identify after accidental swallowing). BSM is approved for the product subject to contacting food due to its nontoxic property. BSM conforms to the Europe 's purity requirement and U.S' codes of food and drug administration.

BLANC FINE¢â, a nano-fine barium-sulfate-based functional additive permits innovative potentials for the optimization of paint properties. A special production process combined with extremely effective after-treatment (coating) guarantees extreme fineness and the product's low conductivity at consistently high levels.
BLANC FINE¢â small particle diameter of less than 0.1 um and its low refractive index, no loss of transparency or gloss in the coated surface occurs. On the contrary: The spherical geometry of the BLANC FINE¢â particles means that gloss is actually enhanced in most cases. BLANC FINE¢â is used for stabilization of organic and inorganic pigments against flocking. BLANC FINE¢â adsorbs on the surface of the pigment and thus prevents agglomeration of the pigment particles. This stabilizing mechanism can be attributed on the one hand to purely steric effects and, on the other hand, this repelling action can also be explained by the electrostatic charge carried on the surface of the BLANC FINE¢â . The use of BLANC FINE¢â in particular permits effective improvement of the orientation of the aluminium flakes in metallic-finish paints.
This product's low binder requirement makes it possible to use BLANC FINE¢â to precisely control the rheological properties of a paint or coating. BLANC FINE¢â additive permits formulation of haze-free high-gloss paints, water-based paint systems, and paints and coatings with a high solids and low solvent content. The addition of a number of percentage points of BLANC FINE¢â reduces the solvent content of the paint system significantly. An increased solids content in a paint reduces the readily-volatile solvents content significantly, thus contributing decisively to the achievement of a lower pollution burden for humans and the environment
