YARFAST® alkyd-urethane enamel — topcoat over YARFAST® primer
One-component alkyd-urethane enamel for metal, concrete and reinforced concrete surfaces in an open industrial atmosphere.

The organosilicon enamel KO-174 Khimtek protects steel structures and mechanical engineering equipment against corrosion in the atmosphere and at high humidity; it is also applied to facades and porous building surfaces. Heat resistance is up to +150 °C, for the silver enamel up to +300 °C. The coating is applied in 1–2 coats by spraying, brush or roller with an interval of 10–15 min between coats; it dries completely at 20 °C in 1 h (silver in 2 h).
