Potters Industries Q-Cel® 7040S Hollow Engineered Glass Microspheres
Categories: Ceramic; Glass; Other Engineering Material; Additive/Filler for Polymer

Material Notes: Q-CEL® hollow glass microspheres are alternatives to conventional fillers and additives such as silicas, calcium carbonates, talc, clay, etc. A variety of particle sizes, densities and strengths meet specific functional and end-use application requirements such as reducing density or cost, or improving stiffness or workability. They are compatible with polyesters, epoxies, phenolic resins, urethanes, plastisols, thermoplastics, latex, concrete and other building materials, as well as emulsion- and water-gel explosives. They are available uncoated, or coated with specially-formulated coupling agents (CP01, CP03) to maximize interfacial bonding between the microspheres and the resin matrix.
