- SNOBRITE® Features and Benefits
- Good color quality, effective TiO2 spacing, and cost-effective rheology modifier with inherent or natural plasticity and thixotropy.
- Moisture barrier, chemical resistance, easy to disperse filler, and opacifier/TiO2 extension.
- 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.
