Esser. 5 Grosvenor Gardens, London, S.W.1 24 June 1961 CHEMICAL AGE ING THE SCALE The electrical water treatment pipe units, made by Aquastat Ltd and used to prevent scale, have their interior surfaces coated with Araldite. This epoxy coating resin is an excellent electrical insulator; it adheres strongly to the metal, is entirely impervious to water over very long periods, and is unaffected by chemicals found in all waters normally in use; it is also highly resistant to abrasion and scouring action. Aquastat Ltd have tested many forms of coating for their pipe units. Araldite, which has been used for the last five years, has proved the most effective and the most economical. Araldite epoxy resins are used- - for casting high grade solid electrical insulation - for impregnating, potting or sealing electrical windings and components - for producing glass fibre laminates - for producing patterns, models, jigs and tools Ias fillers for sheet metal work Araldite r aJ protective Coatings for metal,
