KO-870 Elcon — heat-resistant enamel up to +700 °C for steel structures and concrete
One-component silicone enamel for steel structures and equipment up to +700 °C, also suitable for concrete, brick and reinforced concrete.

The most highly filled version of the range: the dry film of Elcon Zintech 96 contains 96 % zinc, and the binder is modified epoxy ester resin with spherical zinc. The compound is intended for industrial construction, the oil and gas sector, the power industry, port and hydraulic structures, power line towers, bridge piers and decks, and road safety barriers. Work is permitted from −20 °C to +40 °C, a coat dries to degree 3 in not more than 1 h at 20 °C; it is used on its own or under topcoats.
