Silicone coatings designed primarily for temperature indicating applications requiring an irreversible sharp visual color change.

Thurmalox® 884-085

Temperature Indicating Coating

A heat-resistant modified silicone coating system designed primarily for temperature indicating applications requiring a single stage irreversible color change. When applied to refinery and petrochemical process equipment which operate at elevated temperatures the color change provided by Thurmalox 884-085 indicates vessel overheating due to failure of refractory linings, system malfunction or bypassing of hot gases. Thurmalox 884-085 is suitable for maximum continuous operating temperatures up to 550˚F (288˚C).

Color Change Summary

Ambient to 550˚F (288˚C)	Green
650˚ (343˚C) to 950˚F (510˚C)	Green to White

Note: Color change is dependent on variables such as time, temperature and thickness of steel surface. Color change or drift is possible based on these variables. Thurmalox 884-085 may require repainting every 18-24 months depending on operating conditions.
