Apexior No.1 is a special graphite/bitumen compound, designed to act as an anti-corrosive coating for metal surfaces in continuous contact with hot water above 93°C (200°F). It has also been proven to be unaffected by steam reaching temperatures of 540°C (1004°F) while actually improving the boiling characteristics/steam generation patterns of the boiler/plant in which it is used. Indeed it has been shown that heat transmission is increased by up to 35% by the use of this product, giving real energy efficiency and cost savings. It is very easy to apply and maintain and imparts no smell, or discolouration to liquids with which it comes into contact. Price on request.
