Interkron — high-build epoxy primer-enamel for immersion in water and soil

Primer-enamels

A high-build primer-enamel with high solids: the volume fraction of non-volatile matter is 86±2 %, so the working film is built up in a single pass. Interkron is designed for categories Im1–Im4 per GOST 34667.2 (ISO 12944), that is, immersion in water and soil, and is used on hydraulic structures, industrial structures and equipment in contact with water, chemical reagent solutions, mineral fertilisers and petroleum products. The material combines the functions of primer and finish, is approved by TsNIIS and is tinted to the RAL catalogue.
