    Indestructible Paint’s ColourTherm Range of Thermal Indicating Coatings

    Thermal Indicating Coatings

    Indestructible Paint are a leading thermal indicating coatings manufacturer. ColourTherm is our range of high-performance heat sensitive, colour changing coatings. Our ColourTherm range of thermal indicating coatings are designed to change colour at specific temperatures. Therefore, this can very beneficial for a range of industries.

    Thermochromic Coatings

    Our specialist range of thermochromic paints are designed to change colour at specific temperatures, giving a visual indication of a temperature change. They can be used in many temperature critical areas. This includes acting as safety indicators on thermally sensitive substrates and indicating thermal history. For instance, on reaction vessels to indicate hot spots and internal insulation failures for chemical and petrochemical industries. In addition, it can be use for safety measures in R&D development programmes.

    How Does Our Colour Change Paint Work?

    The colour change is non-reversible within this coating range. The paints function by the action of chemical change within solid components of the coating.

    These high-performance thermal-indicating coatings are designed to be thermally stable when used below their first temperature change level. When the coatings approach their first colour change, the reaction will occur quickly at the specified temperature or gradually if the paint is held within a few tens of degrees of the change temperature.
