Film thickness is the most important number on a powder coating specification – too thin and the coating fails early, too thick and it wastes powder and can crack. Here is what thickness you need and how it is measured.

Importing powder coating from China is a proven way to cut material costs – if you know what to specify, what to expect on lead time, and how to avoid the common pitfalls. Here is the process we walk every overseas buyer through.

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). Home Appliances Refrigerators, washing machines, dishwashers, and microwave housings — needs to resist scratches, moisture, and daily wear. Furniture and Architectural

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: 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 coverage can

Temperature and Time Requirements for Powder Coating Cure Curing conditions depend on the resin chemistry of the powder. Typical industry ranges are summarized below. Typical Cure Schedules Standard thermoset (epoxy / polyester / hybrid / TGIC): 180–200°C (356–392°F) for 10–20 min — most common; baseline often 200°C/10min or 180°C/20min. Low-cure / low-temperature: 130–150°C (266–302°F) for

How Charged Powder Particles Coat a Grounded Part Electrostatic spraying is the core application method for powder coating. It works in the following stages: 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 charging (particles

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: 1. Degreasing Parts go through an alkaline or acidic cleaning bath (or spray) to strip oils, cutting fluids, and fingerprints left from
