Durable Labels That Stick: Powder Coat Adhesion Issues

Many OEMs (Original Equipment Manufacturers) choose powder coating over traditional wet paint due to its durability and aesthetic appeal. But while powder coats offer many advantages, they present a unique challenge—label adhesion.

Why OEMs Prefer Powder Coating Over Wet Paint

Powder coating has become the preferred finishing option for many manufacturers. Here’s why:

• Exceptional Durability – Resistant to chipping, wear and tear, and harsh environmental conditions.
• Superior Color Retention – Unlike wet paint, which may fade over time, powder-coated surfaces maintain their vibrancy.
• Cost-Effective – Powder coating can be a more economical choice in the long run.
• Eco-Friendly – Traditional wet paint contains volatile organic compounds (VOCs), which can pose health risks. Powder coating, on the other hand, is a greener alternative.
• Safer to Store – Unlike liquid paints, which are flammable, powder coats pose fewer storage hazards.
• Easy Application – While wet paint requires a skilled hand, powder coating is a more forgiving process.

Given these benefits, many OEMs consider powder coating an upgrade from wet paint. However, there’s one persistent issue: standard labels just won’t stick.

The Challenge: Labels Peeling Off Powder-Coated Surfaces

Manufacturers often encounter an annoying problem—labels falling off, sometimes even before the product leaves the factory. The culprit? Adhesives that were designed for wet-painted surfaces but fail on powder-coated ones.

The texture and chemical composition of powder coats create a challenging surface for traditional adhesives. If your labels aren’t sticking, it’s likely because they were formulated for old wet-paint applications and haven’t been upgraded.
