Q-Cell Additive Filler (QCELL)

Lightweight Microsphere Additive for Fairing & Filling Compounds

Q-Cell Additive Filler (QCELL) is a lightweight microsphere powder designed to be mixed with resins to create easy-sanding fairing and filling compounds.
Manufactured from hollow microspheres, Q-Cell significantly reduces the density of epoxy and polyester resin systems while maintaining good strength and workability. When blended into resin, it produces a smooth, lightweight filler ideal for surface fairing, gap filling and minor repairs. The fine particle structure ensures easy mixing and consistent dispersion, helping achieve a uniform compound that spreads easily and sands smoothly once cured. Compared to heavier mineral fillers, Q-Cell reduces overall weight and improves sanding performance, making it especially valuable in marine, automotive and composite fabrication applications. Widely used in boat building, panel repairs and structural composite work across Australia, Q-Cell Additive Filler delivers professional-grade results where lightweight performance and surface refinement are critical.
