How heat resistant is powder coating?

Best used on demanding or complex paint jobs, powder coating provides a layer of resilience for almost all surfaces and metals.

When powder coating is being professionally applied, part of the process involves the powder being ‘heat bonded’ to the metal or material in question. As well as providing a solid seal around the object, this tempers the coating – allowing it to resist temperatures up to 350 degrees Celsius. As many powder coatings are silicone based, this provides a helpful heat resistant base and allows the coating to act as an additional protective layer against any harm.

If heat resistance is a concern for your coat, there are also a range of specific coatings that have temperature tolerance in mind. This allows you to enjoy quality coverage without having to compromise on the look of your design.

What climates can it be used in?

One of the greatest strengths of powder coating is its ability to be used in a range of environments and climates. 

On average, powder coating can retain its high-quality finish for up to 20 years before it needs to be replaced if used outside. This also carries the potential to last longer if properly cared for or deployed indoors. Conventional hobs finished out by liquid paint may last up to half that, due to their vulnerability to the elements.

This allows your powder coated item to be used in a range of environments. The innate heat resistance of the coating makes it perfect to deploy in warmer climates where other paints could discolour and start to peel – or in situations where temperatures move from extremes of high to low such as industrial environments and regions subject to daily fluctuations that can be hard on more conventional coverings.

Powder coatings also handle cold temperatures well as the application process involves the creation of a tempered seal around the material being covered. This means that even when exposed to frosts or heat, the covering is able to comfortably deal with thermal expansion and contraction. This also applies to environments with high levels of precipitation – ensuring that the material offers a high degree of water resistance and insulation from rust, damp, or rot.

The deployment of a powder coat helps cover up the ‘pinhole’ crevices and cracks that can allow water to seep in or be widened by changes in temperature; creating a reliable cover that looks fantastic into the bargain. This allows you to provide an extra level of protection, get the look that you or your business needs, and save money for the years ahead.
