884-050 Red

Temperature Indicating Coating

A heat-resistant modified silicone coating 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 884-050 indicates vessel overheating due to failure of refractory linings, system malfunction or bypassing of hot gases. Thurmalox 884-080 is suitable for maximum continuous operating temperatures up to 250˚F (121˚C).
