KO-811 Elcon — heat-resistant enamel up to +400 °C per GOST 23122-78

It is manufactured to GOST 23122-78 and is suitable not only for steel but also for aluminium and titanium surfaces of metal structures and equipment. The coating works from −60 °C to +400 °C and holds for at least 5 h at (440±10) °C; flexibility in bending is not more than 3 mm. The palette is limited to five colours: black, red-brown, grey, silver-grey and green; the enamel is applied by air spray in 2–3 cross coats without primer.
