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 BT protects mineral substrates — concrete walls, building and reinforced concrete structures, facades — in mildly and moderately aggressive industrial environments. The primer-enamel on synthetic resins remains vapour-permeable and is applied to a mechanically cleaned and dust-free surface in at least three coats; work is permitted from −20 °C. A coat dries to degree 3 in 2 h at 20 °C, and full cure takes at least 72 h.
