Chlorowax is a type of chlorinated paraffin resin, in the form of a cream colored powder. It is used as a chlorine donor (contains 70% chlorine). Chlorinated paraffins are used as secondary plasticizers for polyvinyl chloride (PVC). Chlorinated paraffins are also used as extreme pressure additives in metal-machining fluids or as metal-working lubricants or cutting oils because of their viscous nature, compatibility with oils, and property of releasing hydrochloric acid at elevated temperatures. They are added to paints, coatings and sealants to improve resistance to water and chemicals, which is most suitable when they are used in marine paints, as coatings for industrial flooring, vessels and swimming pools and as road marking paints. Solvents are xylene, acetone and alcohol.
