Q-Cel is a lightweight filler consisting of hollow inorganic micro spheres with exceptional whiteness and low bulk density and reduced particle size. It is used as a volume extender in any thermoplastic or thermoset resins, such as unsaturated polyesters, epoxies and urethanes where lightweight closed cell structure is required.

Q Cell is added to resin at the rate of .5 – 10% by weight dependent upon application and up to 20% can be added if a paste consistency is required.
