Zeeospheres Ceramic Microsphere are unique gray-colored, fine particle size, high-strength microspheres. They are opaque to visible light, but transparent to UV light. These products are typically used to reduce VOC levels, increase filler loadings, improve hardness, and add burnish, scrub and abrasion resistance to a variety of coating formulations. Due to their low resin demand, high hardness and inert chemistry, these products have found utility in high solids, water reducible radiation - curbale and high durability coatings, powder coatings, and a wide range of premium performance coatings.
The
key raw material from which Zeeospheres Ceramic Microspheres are produced
have become darker over the years. Since many users have products or
applications where color is important, Zeeospheres Ceramics, LLC adds
lighter-colored ingredients, to ensure that the final color of the product is
within the historical range of 64 to 69*. This color control adds cost and
complexity to the production of Zeeospheres Ceramic Microspheres, but helps
ensure color consistency.

FORMULATING
INFORMATION
|
| Zeeospheres Ceramic
Microsphers are best dispersed by using sand, ball and roller mills. For
optimal dispersion, the Zeeospheres should be added to the grind stage, along
with pigments and other filler materials. Use of a dispersant can aid in the
wet-out and dispersion. |
