KO-198 Elcon — weather-resistant silicone enamel for aggressive environments
Silicone enamel for steel structures and reinforced concrete under short-term exposure to acids and mineralised groundwater.

A silver enamel for steel structures and equipment with a working range from −60 °C to +400 °C. The two-component version per GOST 11066-74 is prepared from KO-85 varnish and aluminium powder in a ratio of 100 : 5 (kit — 20 kg of varnish and 1 kg of PAP-2 powder), and the mixture is usable for 8 h; the one-component version per TU 2312-010-49222195-2012 on modified silicone resins and glyphthalic varnish is supplied in 25 kg containers. No priming is required.
