Technical Article 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 […]

Technical Article 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

Technical Article 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

Technical Article 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

Technical Article 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
