NEW

SPHERILEX® AC 45 is a spherical precipitated calcium silicate designed to improve corrosion resistance when added to a coating formulation. It has a typical calcium content (CaO%) of between 6.5-7.5% and a relatively low oil absorption. Due to its unique morphology, it may also enhance film hardness and improve abrasion resistance of the cured coating.
