These general purpose spheres offer very good strength-to-density ratio and making them suitable for a variety of uses – coatings, adhesives, mastics, sealants and thermoset resin systems. Marketplace Description Extended Bullets - Decreases weight in paints and thermosets to improve efficiency and may lower costs
- Delivers stable voids for reduced thermal conductivity and dielectric constant
- Lightweight filler adds durability and scrub resistance to paint formulations
- Low surface area enables higher filler loading in paint formulations for reduced costs
- Provides excellent water and oil resistance for use in underwater applications
- Versatile use – adaptable to a variety of production processes including high shear liquid mixing systems
Application - Spray Layup
- Viscosity Management
- Lightweighting
