AQUEOUS ANTI‐CORROSIVE METAL PRIMERS

A water based anticorrosive metal primer is clearly capable of providing a number of advantages if compared with a solvent‐borne system; these benefits tend to apply wherever solvents can be replaced by water as the carrying medium, and they include reduced cost; elimination of fire hazard; reduced need for ventilation in confined working spaces; easier, quicker cleaning of equipment. From the general environmental standpoint it is also an advantge to reduce emission of solvent vapours to the atmosphere, even though the climate of the UK does not call for the stringent emission controls typified by Los Angeles Rule 66.
