Darvan 7 pt

Liquid. A deflocculant that is user friendy because it has a wider deflocculation curve. Does not deteriorate molds as actively as does Sodium Silicate. Darvan will be damaged if frozen. Therefore, we suggest caution if ordering for shipment to cold regions during the Winter seasons. Please note Darvan products do have a shelf life. Darvan 7 has a 2-year shelf life.
