Carbital SB Coated calcium carbonate Imerys Extenders / Fillers >> Calcium Carbonate, ground Rheology Modifiers / Thickeners >> Mineral >> Precipitated calcium cabonate Acrylics/ Acrylates Polysulfides Silicones (Si) PU - Prepolymers Polyvinyl Chloride (PVC) SEALANT >> Putty SEALANT >> Plastisol Calcium carbonate. Fine ground calcium carbonate is used in a wide range of sealant and adhesives applications to improve rheological properties and reduce water or volatile content of the compound. Carbital SB rheology modification, high whiteness Application: polysulfide, hot melt, bitumeous and polyurethane selants for construction, silicone and hybrid polymer sealants, PVC plastisols, sealant tapes/strips, cavity fillers for automotive, acrylic sealants, and putties and mastics. Used as a sole filler in low-modulus silyl-terminated polyether sealants. Gives increased sealant thixotropy and modulus. Fine ground calcium carbonate.
