PYRAX^® WA

PYRAX^® WA Pyrophyllite is a unique natural mixture of platy silicates, principally pyrophyllite, and quartz. It is coarser than PYRAX B. It is used as a reinforcing filler in joint compound and high build coatings where it improves mud crack resistance. It is also used in sanitaryware where it increases fired strength, provides faster firing cycles, and increases thermal shock resistance.
