Enamel KO-813
Composition
Enamel KO 813 is prepared by mixing 94 parts of varnish KO-815 and 6 parts of aluminum powder and using it within 8 hours after preparation.
Purpose (KO-813)
KO 813 is designed for protective (anti-corrosion) painting of steam pipelines with superheated steam, heat pipes, process pipelines, oil pipelines, gas pipelines, metal chimneys, vehicle exhaust systems, engine parts, ship hulls and mechanisms, metal roofing and metal structures .
Application
KO 813 enamel prepared for application can be applied with a paint sprayer (pneumatic or airless), roller, brush, dipping. When spraying, the nozzle diameter should be 1.8-2.5 mm. The distance from the nozzle of the paint sprayer to the surface to be painted should be 200-300 mm, depending on the air pressure and the diameter of the nozzle.
