THIXO-CARB 300
THIXO-CARB 300
THIXO-CARB® 300 precipitated calcium carbonate (pcc) is a surface treated, ultrafine pcc providing controlled particle size and narrow distribution designed specifically for application in polyurethanes, polysulfides, PVC plastisols, epoxy and butyl systems. THIXO-CARB pcc is a functional additive providing thixotropy and viscosity control resulting in improved sag and slump characteristics. Physical properties are improved due to the semi-reinforcing performance of THIXO-CARB 300 pcc providing the formulator opportunities for cost effective development of high performance sealant systems.
