Description

MAXCOR 700 –  HEAT ACTIVATED EPOXY NOVOLAC COATING is high performance, single pack epoxy novolac coating. The product once cured provides excellent chemical and corrosion resistance at elevated service temperatures.

To enable full material cure MAXCOR 700 – HIGH TEMPERATURE COATING must be applied to hot metal surfaces at temperatures ranging between (100°C – 150°C). Once cured the material is suitable for dry heat applications up to 220°C or immersed conditions up to 60°C 

Due to the application requirements of MAXCOR 700 HIGH TEMP COATING, the material is suited for applications to live pipework and process equipment running above the minimum 100°C.  The material is particularly effective as a coating system to combat the negative effects of corrosion  under insulation (CUI).
