  • Product Description
  • Product Characteristics
    1. Excellent adhesion to steel pipe substrates, with adhesion reaching Grade 1.
    2. The coating film has good leveling, high gloss, high surface hardness, and high coating density.
    3. It has extremely strong anti-permeability and anti-corrosion capabilities, and can withstand long-term erosion and scouring by medium-high temperature water and steam.
    4. The coating has excellent resistance to high-temperature cathodic delamination.
    5. Excellent low-temperature performance; the coating maintains good mechanical properties even at -20℃.
    6. Low melting temperature, high reactivity, and high curing completion rate.
    7. Good mechanical properties and extremely strong flexibility; the coating remains intact even after cutting and grooving.
    8. Meets the safety evaluation standards for potable water protection materials.
    9. Good powder fluidity, large spraying area, effectively reducing dust pollution during spraying.

    Execution Standard: GB/T 28897-2012
    Application Areas: Municipal water supply pipelines, domestic sewage pipelines, central air conditioning drainage pipelines, and other water supply and drainage pipelines.
    Applicable Processes (depending on pipe diameter): Electrostatic spraying, hot melt coating, inner suction and outer spraying, fluidized bed (well) immersion coating, roller coating, etc.
    Precautions:
    　　1. The steel pipe surface should be free of oil stains, loose rust, and moisture; the surface treatment quality should reach Sa2 1/2 grade (GB/T8923); the anchor pattern depth should be 50-90mm; dust and abrasives attached to the steel pipe surface should be blown clean; preheating: the steel pipe surface temperature should be controlled at 160-200℃, not exceeding 230℃.
    　　2. Unused powder should be stored in a ventilated, dry room with a temperature below 40℃, away from heat sources, corrosive chemicals, and chemical solvents, and avoid strong light irradiation; the maximum stacking height should not exceed 4 layers; avoid long-term pressure, ensure that the packaging box is sealed to prevent agglomeration and moisture, affecting coating performance.
    3. In order to maximize the anti-corrosion effect of the epoxy coating, the coated steel pipe needs to be subjected to secondary heating and curing.
    　　4. Do not mix with other anti-corrosion powder coatings and recycled powder, and thoroughly clean the spraying equipment when changing colors to ensure drinking water quality safety and meet hygiene standards.
