EP-773 Khimtek — chemical-resistant epoxy enamel for hot alkalis
Chemical-resistant epoxy enamel for metal surfaces exposed to hot alkalis, over primed and unprimed metal.
The anticorrosion primer YARFAST® based on alkyd-urethane varnish is a one-component material for steel structures and equipment. In a system it is applied in one coat under the alkyd-urethane enamel YARFAST®, and in two coats it works as a stand-alone coating. It can be applied at temperatures from +5 to +30 °C and humidity no higher than 80 %; the primer dries to degree 3 in no more than 4 h at 20 °C or 60 min at 60 °C.
