How to Decide Coatings for PPGI Coil

IBC Steel Group manufacturer PPGI Coils for decades years. It’s very important to choose a suitable coatings for PPGI Coil.

Pre-painted steel is a versatile product, which is widely used in construction, home appliances, furniture, and other industries. Also, on the market there are many options in different base metals, paints, finishes, etc.

There are many PPGI coated coils with different coatings, colors, and coating thickness. You can choose according to your requirements, for example, the use environment, design life, etc. Choose the right coatings is very important for you.

Then let’s talk about how to decide coatings for PPGI coil. 6 steps tell you how do decide it.

Pre-Painted Galvanized Coils - PPGI

Firstly, Coating Types

When choosing a primer, you need to consider the adhesion of the primer; while for top coating, corrosion resistance and color retention will be more important. There are four commonly-used coatings, including Polyester (PE), Silicone Modified Polyester (SMP), High Durability Polyester (HDP), and Poly – Vinyli Dene Fluoride (PVDF).

PE coating is of good adhesion, which is widely used as a primer.

While HDP and PVDF will be more suitable as a top coating because of their excellent durability and color retention.

Secondly, Thickness of Coating

Our top coating is 11-35 μm and the back coating is 5-14 μm. Generally, the thick the coating, the better the corrosion resistance. You can choose according to your requirements. For example, a single layer of back coating is recommended for sandwich wall panels.

The coating thickness has intimate connection with the corrosion resistance of PPGI steel coil, and the corrosion resistance usually improve with the increase of coating thickness. The coating thickness should be confirmed by the environmental corrosiveness, service life and durability.

Thirdly, How to Decide Coatings for PPGI Coil ——Coating Colors

What color is the best? It mainly depends on the use environment, your preference, market demand. For example, beauty is the first concern for civil buildings. But the corrosion resistance is more important for industrial buildings. Besides, the light color paint has a stronger heat reflection ability.

Moreover, the color change of dark colors is more obvious than that of light color. More than that, you can also appoint the paint brands, such as AkzoNobel, Nippon, etc.

There will possible to occur color difference during the produce and use process of PPGI steel coil. The color difference is influenced by the production organization, color, use time, use environment and other factors.

Fourthly, Coating gloss

Gloss mainly choose based on the use and use habits. For example, the building-use PPGI steel coil always choose middle or low gloss, and household appliance PPGI steel coil always choose high gloss.
