Manufacturing Process

Pre-Mixing Phase

  1. Measure all ingredients according to the specified percentages.
  2. Mix the polyester resin, crosslinking agent, and fillers in a high-speed mixer.

Extrusion Phase

  1. Heat the mix to 180°C using a twin-screw extruder.
  2. Ensure the material is extruded uniformly to enhance the molecular structure.

Cooling and Grinding Phase

  1. Cool the extruded material rapidly to prevent degradation.
  2. Grind the cooled material to a fine powder using a grinding mill.

Sieving Phase

  1. Sieve the powder to ensure consistent particle size distribution.

Usage Instructions

Apply the powder coating using an electrostatic spray gun. Ensure the substrate is clean and free of contaminants. Cure the coated components in an oven at 180°C for 20 minutes.
