"CLEAN UP, PAINT UP, FIX UP"... Many of the nation's leading cities are currently observing "Clean-up, paint-up, fix-up" month. Hercules materials play an important role in the maintenance of homes and industrial buildings. Paints, thinners, disinfectants, cleaners, wallpaper are typical of finished products that depend on Hercules resins and other basic ingredients.

A plastic reservoir and lid made from Pro-fax®, Hercules polypropylene, make the new Prak-T-Kal vaporizerhumidifier lightweight, virtually unbreakable, easy and safe to handle and store. The many superior qualities of Pro-fax are leading to the selection of this completely new plastic for many applications that previously could be met only by more costly materials.
