Fillers and Extenders

Silicas for Paint, Rubber, and Reinforcement

Fillers and extenders require heightened visual, physical and chemical property control. U.S. Silica's precision-ground sizes range from 250 to 5 micron top size, and our ground and fine ground silicas are naturally bright white, low in moisture, chemically inert, and contain at least 99.5% pure SiO2. Their acid-resistant durability and chemical inertness make them an excellent product for epoxies, adhesives, coatings, mastics and sealants.

Paint

  • Ground and fine ground silicas feature the tightest particle size distribution curves to allow high loading levels for the most consistent product
  • Benefits include tougher paint film, enhanced durability, longer lasting, improved weathering, increased scrubbability, and better adhesion to substrates

Rubber

  • Very high loading with minimal effect on viscosity and cut rate versus synthetic silicas
  • Excellent semi-reinforcing filler
  • Consistent color, purity and size distribution

Epoxy and Plastics

  • Very high loading with minimal effect on viscosity and cut rate versus synthetic silicas
  • Consistent color, purity and size distribution

Traffic Paint

  • Our products feature high brightness and low oil absorption, making them perfect for traffic paint applications

Semi-Reinforcing

  • Excellent inert semi-reinforcing fillers with high dielectric strength make our ground silica products perform well in electrical compounds
  • Consistent pH and narrow size distributions allow very high loading with minimal effect on viscosity and cure rate
