Manufacturers switch from liquid paint to powder coating for the same reasons: one-coat efficiency, better durability and no solvent emissions. But powder is not always the answer. Here is an honest comparison.

Epoxy and polyester are the two most common powder coating chemistries. Choosing the wrong one usually means poor outdoor durability or unnecessary cost. Here is how to decide.

Color is often a contract requirement, not just a preference. Learn how RAL, Pantone and custom color matching work, and what to send us for an exact match the first time.

Common Applications of Powder Coated Products Powder coating is used across a wide range of industries because it is durable, environmentally friendlier than liquid paint, and available in many finishes (matte, gloss, textured, metallic). Key Takeaways Home Appliances Refrigerators, washing machines, dishwashers, and microwave housings — needs to resist scratches, moisture, and daily wear. Furniture

Quality Control Checks After Curing After curing, parts pass through a cooling zone (ambient or forced air) before quality control checks. Key inspection metrics include: Key Takeaways Coating Thickness Measured with a magnetic or eddy-current thickness gauge (non-destructive). Typical target: 60–120 microns (2.4–4.7 mils), depending on application and spec. Checked at multiple points since spray

Powder Coating Cure Temperature and Time Most standard powder coatings cure at 180–200°C (356–392°F) metal temperature for 10–20 minutes. The cure clock starts when the part itself reaches the specified temperature, not when the oven reaches its setpoint. Low-cure products can cure at about 130–150°C for 15–30 minutes, while some fast-cure systems use about 200°C

How Charged Powder Particles Coat a Grounded Part Electrostatic spraying is the core application method for powder coating. It works in the following stages: Key Takeaways 1. Charging the Powder As powder particles pass through the spray gun nozzle, a high-voltage electrode (typically 60–100 kV) gives each particle a negative electrostatic charge, either by corona

Surface Preparation Before Powder Coating Pre-treatment prepares the metal surface so the powder coating bonds properly and doesn’t fail early from rust or contamination underneath. It typically includes the following stages, in order: Key Takeaways 1. Degreasing Parts go through an alkaline or acidic cleaning bath (or spray) to strip oils, cutting fluids, and fingerprints
