Boric Acid (H3BO3, CAS 10043-35-3) is a white crystalline solid (density about 1.51) that dissolves slowly in water, about 5% at room temperature and more when heated, to form a very weak acid. It is used in fiberglass and borosilicate glass, flame retardants, nuclear reactor coolant control, wood preservatives, insecticides and mild antiseptics. Boric acid solutions are usually stored warm or dilute to prevent crystals settling out. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
HDPE is the most economical tank material for Boric Acid, rated Excellent. Polypropylene, PVDF (Kynar®) and nylon are also rated Good or better. Avoid aluminum hardware.
