Using Expancel microspheres as a lightweight filler in paint will shorten the drying time, introduce a matting effect and provide good filling on uneven substrates. Plus, the low density of the microspheres will reduce the weight of the paint even with small dosages. Expancel microspheres will also reduce the need for solvents in solvent-based paint – leading to a reduction in VOC emission. For lighter, real quality and longer-lasting paints.
