IZOLEP-235 — epoxy primer-enamel for ships, ballast tanks and hydraulic structures

Primer-enamels

A two-component high-build primer-enamel on a modified epoxy resin with a polyamine hardener, capable of curing at sub-zero temperatures. It is designed for full immersion and the variable level of sea and fresh water, contact with mineral oils, petroleum products and domestic wastewater, and withstands abrasive wear and impact loads. It is used in ballast tanks, on decks and hulls of ships, in hydraulic structures and pressure vessels — over carbon, galvanised and stainless steel; it works on its own or over IZOLEP-eps and IZOLEP-SP-03 primers.
