Thermoplastic PP Polypropylene Powder Coating
PECOAT® Polypropylene Powder Coating
PECOAT® Thermoplastic Polypropylene(PP) Powder Coating is a thermoplastic powder coating prepared from polypropylene, compatibilizer, functional additives, pigments and fillers. The product has excellent corrosion resistance and mechanical properties, very high hardness and wear resistance.
PECOAT® polypropylene powder coating is designed for dishwasher basket, metal furniture, and metal items with specified requirement of wear resistance and high hardness. In some cases, it can replace nylon powder coatings.
- Coating thickness(GB/T 13452.2): 250~600μm
- Bending (GB/T 6742): ≤2mm (Thickness 200µm)
- Shore Hardness D(GB/T 2411): 60
- Adhesion (JT/T 6001): 0-1 level
- Food Contact Testing (EU standard): Pass
- Particle Size : ≤250um
- Weather Resistance(1000h GB/T1865): No bubbles, no cracks
- Melting point: 100-160℃
We can offer any bespoke colour to match your needs.
Fluidized Bed Dipping Process
- Pretreatment: Clean and remove rust and oil. In order to achieve the best adhesion of the coating, it is recommended to use phosphating treatment on the substrate
- Workpiece preheating: 250-400°C (adjusted according to the workpiece, ie metal thickness)
- Dip in Fluidized Bed : 4-8 seconds (adjusted according to the metal thickness and shape of the workpiece)
- Post-heating to curing: 200±20°C, 0-5 minutes (this process make the surface better)
- Cooling: air cooling or natural cooling
25Kg/Bag
PECOAT® thermoplastic polypropylene powder is firstly packaged in a plastic bag to prevent the product from being contaminated and damp, as well as to avoid powder leakage. Then, packed with a woven bag to maintain their integrity and prevent the inner plastic bag from being damaged by sharp objects. Finally palletize all bags and wraped with thick protective film to fasten the cargo.
Now ready for delivery!
Different substrate condition has different requirement for coating property, such as adhesion, flowing ability, temperature endurance, etc, these information is the basis of our sample design.
To maximize the chances of success of sample testing, and being responsible for both parties, kindly please supply the following information. Thank you so much for your serious treatment and cooperation.
- What product do you coat? It is better to send us a picture.
- What is the substrate material, galvanized or non-galvanized?
- For sample testing, 1-25kg/color, send by air.
- For formal order, 1000kg/color, send by sea.
- Mechanical removal: Use tools such as sandpaper, wire brushes, or abrasive wheels to scrape or grind off the coating.
- Heating: Apply heat to the coating using a heat gun or other heating device to facilitate its removal.
- Chemical strippers: Use appropriate chemical strippers specifically designed for powder coatings, but follow safety precautions when using them. This is a strong acid or a strong base.
- Sandblasting: This method can remove the coating but need sandblasting machine.
- Scraping: Use a sharp tool to carefully scrape off the coating.
