Incandescence is the emission of light by a solid that has been heated until it glows, or radiates light. When an iron bar is heated to a very high temperature, it initially glows red, and then as its temperature rises it glows white. Incandescence is heat made visible – the process of turning heat energy into light energy. Heat Resistant Paint, our core product, is a high quality fast drying, high temperature paint for use on many steel and cast iron products which reach temperatures of up to 650°C. It is available in over 20 colours and is supplied in many different formats including 200ml and 400ml aerosols plus ½ litre, 1 litre, 5 litre and 20 litre tins.
