The product has good dispersion
properties, thixotropic properties, and transparency. Suitable for light-curing
coatings, it improves printability, reduces fogging and high levels of filling,
and is halogen-free.
An ultrafine barium sulfate product subjected to wet high temperature surface
treatment using inorganic materials. The wet high-temperature coating process
makes the barium sulfate particles have good dispersing properties, and has
excellent steric hindrance in other pigment components, and utilizes the
interaction of different charges on the surface of the particles of other
particles of the particles to effectively isolate the agglomeration of the
pigment particles. The degree of opacity of each pigment component is utilized
to reduce the amount of pigment used and further optimize the cost structure.
The hydrated oxide formed by the inorganic coating can facilitate the reaction
with the acidic functional group of the organic substance, is adsorbed on the
surface of the barium sulfate particle in the alkyd resin, and dissociates into
the electric double layer in the presence of a small amount of water, so that
the barium sulfate particle band is intact. Positive charge, adsorbing a layer
of resin on the surface, due to the protection and wetting of the resin layer,
the dispersion of barium sulfate particles becomes extremely strong; at the
same time, the inorganic oxide coating component forms a protective layer on
the surface of barium sulfate. It also reflects light to the greatest extent,
which increases the gloss of the coating and supports a near-perfect color
development. |
