POLITON-ZP — polyurethane direct-to-metal primer-enamel (DTM)

Primer-enamels

POLITON-ZP combines primer and finish in one material: a polyurethane on a modified polyacrylic resin with the corrosion inhibitor zinc phosphate, applied directly to metal (direct-to-metal). It is suitable for steel structures and concrete in atmospheres of categories C2–C5 per GOST 34667 (ISO 12944), is UV-resistant and is tinted to RAL. Besides stand-alone use, it serves as an intermediate or finish coat in epoxy and polyurethane systems and as a repair finish over them. Service is from −60 °C.
