OS 51-03 CERTA for heating mains — heat-resistant organosilicate composition to +300 °C
Organosilicate composition for the outer surface of heat and steam pipelines laid in ducts, tunnels and above ground, up to +300 °C.

Certacor 710 is designed for corrosivity categories C1–C4 per ISO 12944-2 and is intended for metal, concrete and reinforced concrete structures in aggressive gas-air media: trestles, power line towers, vessels. It is applied without primer or over CERTACOR 01, GF-021, VL-023 primers, and on concrete over CERTACOR POLISIL. The coating works from −60 °C to +200 °C; AGM-9 hardener is added for flexibility.
