TSVES-SP — ethyl silicate pre-fabrication primer (shop primer)
Zinc-containing shop primer for automatic lines in steel fabrication and shipbuilding: interim protection up to 1 year, welding and cutting through the coating.

An antistatic epoxy coating for the internal surface of storage tanks, containers, tank cars and process pipelines where light petroleum products and aviation fuel are stored and pumped. An additive that increases electrical conductivity provides a volume resistivity of no more than 10⁹ Ω·m, so the coating does not accumulate static charge. It is resistant to petrol, aviation and diesel fuel, gas oils, white spirit, liquefied natural gas and sea water; it is approved by FSUE GosNIIGA, and the predicted service life is 20 years.
