WHEN TO USE PVDF AND PVC COATING ON INSULATED METAL PANELS?

Recently, a customer asked me to explain the difference between the various types of steel coatings on insulated metal panels. Why is it important to know that? Because each type of coating has different characteristics that create a real customer advantage. So in this post, we will show you examples of when to use PVDF and PVC coating on insulated metal panels.

WHAT IS COATING FOR INSULATED METAL PANEL?

The steel coating for insulated metal panels, called also “facing” of insulated metal panels is the top layer of the insulated panel. It may be coated in different colors and have different quality levels. It may be used on galvanized steel sheets or aluminum. The coating type for the top layer is chosen according to the place of application and desired characteristics. The coated metal life span depends on how its chemical structure protects the metal from corrosion.

WHAT ARE THE TYPES OF COATING OF INSULATED METAL PANEL?

1. Polyester
2. PVDF
3. PVC or PET
4. Plastisol

PRACTICAL RECOMMENDATIONS: PVDF AND PVC COATING ON INSULATED METAL PANELS IN DIFFERENT AREAS OF USE

INDUSTRIAL REFRIGERATION

If the customer builds a refrigerated warehouse in an area where the surrounding environment is very aggressive, it is necessary to choose the coating that protects the steel sheet from aggressive corrosive agents. For example, PVDF coating.

EXAMPLES OF AGGRESSIVE ENVIRONMENTS

1. Marine or polluted environment
2. Animal farming
3. Sea-food and fish processing plants
4. Meat or chicken processing plants, as the coating has to be resistant to heavy-duty cleaning.

PROTECTING COLD – ROOM FROM SCRATCHES

How to keep the internal environment of our cold room always clean and protected from scratches that can cause corrosion? Use a type of coating with scratch-resistant characteristics such as a PVC.

MAKING COLORS OF A BUILDING LAST OVERTIME 

How to build a colorful building with colors that last over time in a sunny area? Think about PVDF coating that offers superior characteristics of resistance to ultraviolet rays.

COLD – ROOM WITH A HIGH STANDARD OF HYGIENE

And what kind of pre-painting should we use if we want to build a cold room with a high standard of hygiene?

In this case, we certainly recommend a PVC coating. This insulated metal panel coating resists to heavy-duty cleaning and prevents its molecular structure from degradation. We recommend choosing a cold white tone, as it makes easier to detect dirt during the cleaning.

CONCLUSIONS

Metal coatings for insulated metal panels are not all the same, although they may look similar. Here you can find practical recommendations on what to consider when choosing an insulated metal panel for your project. Please contact us with any further questions at sales@globepanels.com.
