AN intermediate primer that is free of chromates yet fully resistant to attack by aircraft hydraulic fluids and with a lower water permeability than chromate-containing alternatives is now available from the Netherlands-based Akzo Coatings. Consisting of modified phosphate pigments in an epoxy polyurethane carrier, the primer offers the corrosion protection and paint-curing reactivity of conventional primers but without their associated health hazard risks. This is of considerable importance both in view of labour safety during manufacture, and freedom in application.
