SPHERILEX® AC 45 HS

SPHERILEX® AC 45 HS (formerly EXP 9111-2) is a spherical precipitated calcium silicate designed to improve corrosion resistance when added toa coating formulation. It has a typical calcium content (CaO%) of between 6.5-7.5%and a higher oil absorption than SPHERILEX® AC 45. Due to its unique morphology, it may also enhance film hardness and improve abrasion resistance of the cured coating.
