Silica Coating and Silica Paints Applications

 

Zeolex® 330 Sodium Aluminosilicate

Zeolex® 330 is an amorphous sodium aluminosilicate powder for use in silica paints and silica coatings applications as a TiO₂ extender 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 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.

 

Silica for Rheology and Thixotropic Enhancement

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

Instead of using fumed silica thixotropes in your industrial coatings or gel coats, consider a less dusty and cost-effective approach:

Replace some or all of your fumed silica with Zeothix® 265 finely milled precipitated silica from Huber Engineered Materials. The rheology you get from Zeothix 265 improves the uniformity of your film’s thickness, especially for edge coverage. While it offers excellent flowability during application, it re-hardens effectively, forming a superior gel coat that will not sag.

Zeothix 265 is also much easier to work with during formulation. Although it’s a fine powder, it is more dense and easier to disperse than fumed silica. This means:

Less dust in manufacturing Shorter mixing times Greater flexibility when you add the silica (Zeothix can be post added in-house or on-site) Better weathering (and less “alligatoring”) Less likelihood of air being incorporated into the film

 

 

 

 In addition to Zeothix 265's exceptional rheology enhancement, Huber markets 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.

Zeothix® 177 is ideal for gel coatings with long term water exposure, such as boat coatings. Zeothix 177 has a low salt content, which makes it resistant to blistering and warping.

 

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. Best of all: You get all of these advantages at a lower cost than fumed silica.
