Technical characteristics of heat resistant spray paint

As the name implies, this is a type of paint that can withstand high to very high temperatures. Unlike radiator paint that can only be used with temperatures of up to 120°C, heat resistant paint is suitable for 400°C - 900°C, with some of them even withstanding up to 1200°C.

Heat resistant paint has corrosion, heat and scratch-resistant properties. There are also thermal paints available that are petrol, oil and weather resistant, meaning you can paint surfaces such as vehicle parts, barbecues, fireplace inserts and other heated surfaces.

Heat resistant paint: tins or sprays?

Tins

Perfect for painting large surface areas, heat resistant paint in a tin is the ideal format for flat surfaces such as electric radiators.

Sprays

The advantage of sprays is that the paint can get into difficult to reach nooks and crannies, such as cast-iron central heating radiators and car parts. Spray paints have another advantage thanks to their composition: high resistance.

Likewise, if you know how to use spray paints properly, the result will be much cleaner: say bye-bye paint roller or brush marks!
