    Preparation of the specimen

    1. Abrasive blasting to Sa2.5 near-white metal with surface profile of 50-100 microns. Then, clean the surface with high pressure gas
    2. Put the specimen into the oven (200℃), preheat 40-50min
    3. Spray the powder to the preheated specimen with electrostatic spray gun, then place it in the oven, keep it there for 5-10 minutes at 200℃, then cool it to room temperature.
    4. The dry film thickness should be 350±50µm

    Specifications

    Surface Preparation
    Remove all surface contamination before abrasive blasting. Blast clean using steel grit to Sa2.5 near-white metal with a minimum surface profile of 50-100microns.
    Application
    Factors such as plant capability, specifications, and pipe construction or characteristics can affect application conditions. The recommended application temperature range for 3PE 3PP systems is 180-220ºC.
    Recommended Film Thickness(µm)
    120~350μm
    Storage
    1. The product should be stored in a cool, ventilated, dry room with temperature below 30℃ and humidity below 65%. 2. Keep away from fire and heat and tide. 3.After use, it should be sealed in time to prevent powder from being been polluted and damped. 4. Reduce the number of movements to avoid impact and pressure. 5. The maximum stacking height should not exceed 5 layers.
    Package and Handling
    The package is a 25kg box, lined with polyethylene plastic bags. During shipment, it should be loaded or unloaded lightly and avoid direct sunlight, heat, and moisture.
