High temperature resistant coating for optimised processes

When a substrate is subject to heat and rapid temperature fluctuations, it can lead to surface breakage and corrosion. Electrical and engine components, chimneys and ovens, pipework and chemical plants, all these are exposed to possibly damaging temperatures and conditions. A high temperature resistant coating works to protect the substrate from fluctuations and extremes of temperature without losing functionality. As well as protecting from heat, these coatings:

  • Protect from corrosion under insulation (CUI)
  • Effective temperature range up to 1000°C
  • Abrasion resistant

  • Reduce thermal fatigue
  • Extends component life
  • Allow for higher operating temperatures

In this article we take a look at the different categories of high temperature resistant coatings and explain how to choose the right one for your project. Here you will also find some product suggestions and heat resistant coating contractors in Vietnam.

How to choose the best high temperature resistant coating

As with any coating application, understanding the needs of your substrate and the application process is crucial for making the right coating choice. As well as knowing the substrate type, you need to know its environment, its use, the coating time parameters, and the likely ways it will fail. Here are some questions you need to ask before you can choose a high temperature coating:

The maximum operating temperature on the substrate
One of the most common reasons for failure is expecting high temperature coatings to perform outside of the temperature range they were manufactured to tolerate. Each coating type has a specific temperature range, and outside it the functionality and efficacy fails. Make sure not to understate the maximum temperature.
For example, International Intertherm 50 is recommended for temperatures up to 540°C

Possible insulation
If you are choosing a heat resistant coating for metal to combat CUI, that coating needs to be specially formulated for the purpose. It needs corrosion resistance, but it also needs to be able to be applied to hot substrates and deal with boiling water exposure.
For example, PPG HI-TEMP 1027 is designed to prevent CUI and can be applied to hot substrates

Substrate temperature during application
There are high temperature coatings formulated for hot (up to 300oC) and ambient temperature application. A hot application may be required to avoid needing to shut down operations, spot coating problem areas, and generally not disrupting a facility.
For example, Jotun Epoxy HR can be applied on substrates up to 150oC

An introduction to the different types of heat resistant coating

High temperature coating is the one that protects surfaces from overheating and failing due to high heat. Note that these coatings do not necessarily protect from flames. Essentially, heat resistant coatings can be divided into four types.

Heat resistant sprayed metal coatings

Temperature resistance: from -50  to +550°C

Of all the sprayed metal coatings, thermal spray aluminium (TSA) is the most common. TSA and sprayed metal and metal additive coatings are usually applied on steel to provide protection from corrosion and high temperatures.

Uses: Thermal sprayed aluminium is particularly used as high temperature coatings for steel for CUI prevention in onshore and offshore platforms and processing plants.
Benefits: Excellent corrosion protection combined with heat resistance.

Liquid high temperature coating

Temperature resistance: Up to +550

The liquid high temperature coatings are usually either epoxy or silicone based. The general rule is that the more silicone the coating contains the higher temperatures it can resist. These coatings exist as single and two component systems and are formulated on water or solvent base.

Benefits: Liquid paints have the benefit of being able to be applied to hot substrates without affecting the coating.
Uses: Applied at new construction, on-site and as a maintenance coating.

High temperature powder coatings

Temperature resistance: from 200 to 600°C

As well as being corrosion resistant, high temperature powder coatings have been developed for heat resistance to medium to high temperatures. The powders are usually epoxy and silicone-based (like the liquid paints), and silicone-based powders perform better at higher heats.

Benefits: being VOC free and having a wide range of gloss and colour finishes
Uses: Becoming more and more popular as high temperature resistant coating for metal; can be applied instead of liquid heat resistant coating on ferrous metals (steel) offsite.

Ceramic heat resistant paints

Temperature resistance: up to +1000

The heat resistance properties of ceramic coating are well known, and some of the highest heat coatings available are ceramics. Ceramic coatings are known among car enthusiasts for manifold and engine component protection, but they also have a reputation as industrial heavy duty and offshore high temperature resistant coating.

Benefits: Heat resistant ceramic paint also provides corrosion protection and chemical resistance and a hard finish.
Uses: applications that require the highest protection from temperatures: car underhood parts, heavy duty industrial machinery, offshore structures etc.
