Abstract
A mineral filler composition for use in covering products may include first and second inorganic particulate material fillers having respective first and second average particle sizes, wherein the first average particle size is larger than the second average particle size, and wherein at least one of the first and second inorganic particulate material fillers is hydrophobic. A covering product may include a resin and the mineral filler composition. A method for at least one of improving filler loading and water resistance in a covering product including resin, may include providing the mineral filler composition including blended first and second inorganic particulate material fillers, and adding the blended first and second inorganic particulate material fillers to the resin.
