Silica for TiO2 Extension

The ZEOLEX® line of amorphous silicates are high performing, large particle size and prime pigment extenders used primarily in flat white paints to extend Titanium Dioxide. Up to 20% of Titanium Dioxide can be replaced with ZEOLEX® products. Use of ZEOLEX® products results in a much higher contrast ratio, tint strength, and brightness while providing lower sheen than conventional mineral extenders. Additionally ZEOLEX® products allow much smoother, more seamless touch ups than competitive titanium dioxide extenders. For high quality paints, nothing compares to the seamless touch up that the ZEOLEX® series offers.

ZEOLEX® 330 is an amorphous sodium aluminosilicate powder for use in silica paints and silica coatings applications as a TiOextender and gloss sheen control agent. ZEOLEX® 330 provides excellent opacity, whiteness, brightness, flatting and scrub resistance for interior architectural formulations. For more information, click here.

Silica for Rheology and Thixotropic Enhancement

Greater rheology control. Quicker dispersion. Lower cost. Thixotropic. Yes, you can have all four. 

In addition to ZEOTHIX® 265's exceptional rheology enhancement, we have several other ZEOTHIX® products for rheology control in coatings:

ZEOTHIX® 95 can also be used as a cost effective silica for body patches and gel coats.

Silica for Superior Matting

ZEOTHIX® 95 is a finely milled, untreated precipitated silica which reduces the gloss of coatings. In solvent-based coatings, it also increases viscosity for settling resistance. In clear coatings such as lacquer or varnish, it offers exceptionally high clarity and transparency. Unlike other silicas for flatting, ZEOTHIX® 95 is not wax treated, which means exceptional clarity and much lower costs.

To achieve a gloss level ranging from 15 to 45, ZEOTHIX® 95 is used in applications such as: Pigmented Industrial Coatings, Clear Overprint Varnishes, Deck Stains and Fabric and Leather Coatings.
