Therm-O-Signal Temperature indicating paints

Therm-O-Signal coatings are temperature sensitive coatings, which by a perceptile change in colour, indicate that a pre-selected temperature has been reached or has been exceeded. They are extremely useful to monitor temperatures on those places where for any reason other methods, such as thermocouples, cannot be applied.

Typical applications are refractors in the petrochemical industrie, heat sterilisation, critical parts of electronic equipement, observation of oven temperatures, circuit breakers etc.
