Zeeospheres Ceramic Microspheres N Series are
unique dark 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 N Series is typically used when
color is not important in the application.

MATERIAL DESCRIPTION
Shape:
Hollow spheres with thick walls
Composition:
Silica - Alumina Ceramic
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.
