Calcium hydroxide is used as a flocculant in water and sewage treatment. It is also used in fresh water treatment to raise the pH of the water thereby controlling the corrosion of pipes. It is widely used in the production of calcium stearate. It is an active ingredient in whitewash, mortar and plaster. This compound is also used in the petroleum refining industry for the preparation of additives to oils and in the preparation of dry mixes for painting and decorating. It finds application as an antifungal and antimicrobial preservative for vegetables in storage.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
