KO-85 Elcon — colourless heat-resistant silicone varnish up to +250 °C
Colourless silicone varnish for metal, concrete, brick and asbestos cement up to +250 °C; the base of KO-814 silver enamel.

KO-8104 enamel made by Elcon performs two tasks: it protects metal against corrosion when heated up to +700 °C — steam pipelines, furnaces, equipment — and serves as atmospheric paint for concrete and brick. It is based on modified silicone resin with a solution of pentaphthalic resin, manufactured to TU 2312-010-49222195-2012. No priming is needed, work is carried out at temperatures from −30 °C to +40 °C, and the palette is wide, with tinting to RAL K5.
