gRADES OF CT TALC
CLICK TO EXPAND
This talc can be used in coatings and construction applications where high brightness is not required. This talc has good chemical resistance and, when added into paint and coating formulations, improves corrosion resistance, water permeability, and film integrity. It can be used in construction products including: joint compound, adhesives, sealants, putties, caulks. Other recommended applications include areas where a platy particle structure is needed to improve spreadability and application properties while controlling overall formulation cost.
