Talc MP 44-26 is designed for use in interior and exterior architectural coatings as well as industrial primers and topcoats. Talc’s chemically inert nature improves the weatherability of coatings containing talc. The hydrophobic nature of talc contributes to the rheological properties (anti-sag, leveling, and brushability) and gloss of the coating as well as providing sheen control. In addition, the softness of talc reduces wear on processing equipment.
