SNOBRITE White Extender Pigments

SNOBRITE white extender pigments are produced from airfloated intermediate kaolins. With a plate like crystal structure and high aspect ratio SNOBRITE provides good reinforcing properties, increased hardness and stiffness, and improved resistance to abrasion and tear. Its tendency to slowly build viscosity makes SNOBRITE a cost effective formulating tool to enhance performance without adversely affecting production rates. SNOBRITE additions also improve critical working properties, including extrusion, calendering, mold release and handling. In molded and extruded rubber, SNOBRITE can be loaded to relatively high levels and still produce pliable compounds with good durometer values. Unlike finer particle clays, SNOBRITE will not absorb accelerators or adversely affect the cure rate. This is especially important in precision parts where shrinkage and extrusion properties need to be balanced with mechanical strength, hardness and resistance to tear. The high loading and low shrinkage characteristics of SNOBRITE are valued in a wide range of synthetic and natural rubber products, including roofing, footwear, wire and cable jacketing, hose, mill rods, commercial and residential roll matting, soft and novelty rubber goods and polyester gunks. Selectively mined to maximize whiteness and GEB values, SNOBRITE is particularly effective in systems where color is critical. Combined with light scattering properties which mimic more expensive opacifiers, SNOBRITE offers functional performance in a wide range of adhesives, sealants, caulking compounds, and mastics. In alkyd and water based coatings, the combination of particle shape and particle size distribution operate to improve film properties, including surface finish, permeability, scrub resistance, and hiding power. All SNOBRITE grades are mined, processed and sized under rigid Covia QIPSM statistical quality assurance programs. The result is consistent physical properties and uniform particle size distributions for reliable performance.
