PYRAX^® B Pyrophyllite is a unique natural mixture of platy silicates, principally pyrophyllite, and quartz. As a replacement for mica, PYRAX B is an excellent filler in joint compounds and dry wall muds. PYRAX B imparts mud crack resistance to high build coatings such as texture paints and block fillers. PYRAX B is a good inert filler for use in contractor flat paints, where it contributes to improved low angle sheen control and scrub resistance. When used in exterior paints, the neutral pH of pyrophyllite yields reduced frosting.
