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.

Elcon Epoxy is designed for moderately and highly aggressive industrial atmospheres in the chemical, gas, oil and metallurgical industries, marine climates, and immersion in soil and water — from tanks and bridges to hydraulic and port structures. The primer-enamel on epoxy resin with E01 amine hardener contains 80–90 % non-volatile matter and withstands 25 % NaOH, 5 % H₂SO₄ and 3 % NaCl for at least 5 days. It serves as a primer or intermediate coat under Elcon PU; the system is designed for 20 years.
