Elcon PU weather-resistant polyurethane enamel — chemical-resistant topcoat
Two-component semi-gloss polyurethane enamel for tanks, bridges, equipment and concrete; topcoat over Elcon Epoxy, from −60 °C to +125 °C.

An organosilicate composition on silicone varnish with alkyd resin serves as a primer or stand-alone coating for facades, concrete, brick and metal. Elcon produces three versions: up to +100 °C (service life up to 5 years), the standard one from −40 °C to +150 °C and OS-12-03 Elcon from −60 °C to +300 °C with adhesion of not more than 1 point. Metal is painted in 2–3 coats, concrete and brick in three; application is possible from −30 °C (the version up to +100 °C — from −20 °C).
