ETON-Infra — epoxy internal flow coating for gas pipeline pipes
Factory-applied epoxy coating for the inner surface of trunk gas pipeline pipes that reduces gas-dynamic losses, more than 90 % non-volatile matter.

A UV-resistant finish coat for anticorrosion systems: a two-component acrylic-urethane enamel tinted to the RAL catalogue. Per ISO 12944 it is designed for categories C1–C5M and CX, as well as Im1–Im3, and is used on bridge spans, corrugated pipes, sheet piling, power line towers, tanks, above-ground pipelines and mining equipment. The enamel is applied over the primers “Epokron”, “Protekron” and “Primakron”, on concrete over the varnish “Eteral” or the “KronFlex” system; work is permitted at temperatures from −10 to +40 °C.
