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.

FL-03K Khimtek is a primer to GOST 9109-81 based on a phenol-formaldehyde varnish modified with vegetable oils; it is produced in brown, yellow and grey. It is used on steel structures, bridges and equipment as a primer under most solvent-borne enamels. The coating is resistant to temperature changes from −60 to +100 °C, to industrial oil for at least 72 h and to 3 % NaCl for at least 24 h.
