Thurmalox® 70C

Stainless Steel Coating

Stainless steel coating prevents chloride induced external stress corrosion cracking to 1000F
Data Sheet

Thurmalox 70C is a VOC compliant, air drying, silicone based heat resistant coating that protects thermally insulated austenitic stainless steel from chloride induced stress corrosion cracking. Thurmalox 70C withstands temperatures to 1000°F (538°C). It is formulated to contain the minimum amounts of attainable chlorides, halides, sulfides, nitrates and metals that induce external stress corrosion cracking. Every batch of Thurmalox 70C is tested by an independent laboratory for leachable chloride content.

Thurmalox 70C is formulated to meet the currently accepted practice for selection of protective coatings for stainless steel surfaces under thermal insulation as set forth in NACE Technical Committee Report 6H189 “A State-of-the Art Report of Protective Coatings for Carbon Steel and Austenitic Stainless Steel Surfaces Under Thermal Insulation”.

Common Uses
Application to stainless steel surfaces where (1) the benefits of Thurmalox 70C are needed, and where (2) federal, state and/or local authorities require high temperature coatings to be compliant with reduced VOC (volatile organic compound) emission regulations.
• Insulated stainless steel piping, vessels and equipment
• Nuclear power facilities where a high temperature coating for stainless steel with minimum amounts of chlorides, other halides, nitrates, sulfides and metals is needed
