SK-PROTEKT primer-enamel — single-coat polyurethane coating for metal

Primer-enamels

The SK-PROTEKT primer-enamel makes it possible to manage with one material: a single coat with Sa 2½ preparation is designed for UKhL1 and KhL1 climates and a service life of at least 15 years. It can be applied after manual cleaning to St 2 or over a firmly adhering old coating, which simplifies maintenance painting of steel structures, bridges, equipment, oil and gas facilities and chemical plants. The coating is tinted to the RAL catalogue, is resistant to UV radiation and is included in the technological regulations of PJSC Uralkali.
