A two component, high temperature resistant topcoat based on inorganic silicate technology. Intertherm 181 has been specifically designed for application over inorganic zinc primers, which provides a single specification to be used for the protection of all pipework from corrosion at continuous operating temperatures up to 400°C (752°F), and intermittent temperature surges up to 500°C (932°F). Ideally suited for use in the petrochemical industry, especially refineries and offshore structures, where significant volumes of insulated and uninsulated pipework can be coated with a single sp
