IZOLEP-mastic — epoxy primer-enamel over rust and old coatings

Primer-enamels

A high-build epoxy primer-enamel that can be applied over tightly adhering rust and old GF-021, FL-03K, VL-023 coatings, including at air temperatures down to −10 °C. It is suitable for steel structures, bridges, pipelines, oil and gas and port facilities, as well as for concrete: categories C1–C5 and CX per GOST 34667, for immersion — Im1–Im3 per ISO 12944. It works on its own or as a primer under POLITON-UR (UV), VINIKOR-62 and PLAMCOR fire protection; the silver-grey version with aluminium powder is intended for heating network pipes under thermal insulation.
