Product Description：
JN polyethylene powder coating is a thermoplastic powder coating prepared from materials such as polyethylene resin, functional additives, fillers, pigments, etc. It has excellent weather resistance, electrical insulation, chemical stability, flexibility, and low temperature resistance. In addition, the adhesion performance, weather resistance, and adhesion of the film can be improved according to customer needs.
Application Area：
It is suitable for battery containers, net basket type crafts, and air conditioning outdoor unit exhaust filter screen coating.
Powder coatings Properties：
Dry fluidity: fluidization floating ≥20%
Non-volatile content: ≥99.5%
Particle size distribution: ≤300um
Specific gravity: 0.91-0.95 (varies by different colors)
Melt index: : 5-50 g/10min (2.16kg, 190℃) (depending on the workpiece to be coated and the process).
Storage:
Store in a ventilated, dry room/ warehouse/place, below 35℃ to prevent proximity to the fire source. The storage period is two years from the date of production. After the expiration date should be retested, qualified can still be used. In addition, it is recommended to use the products in a first-in, first-out principle.
Packing: Using composite kraft paper bag packaging, each bag net weight of 25 kg.
Instruction:
Pre-treatment: High temperature method and solvent method, or chemical method and sandblasting method to remove rust. After the treatment, the substrate surface shall be neutral.
The preheating temperature of the workpiece is 250-350℃, it can be adjusted according to the heat capacity of the workpiece (i. e., metal thickness).
Fluidized bed dip coating for 4-8 seconds [it can be adjusted according to the metal thickness and the shape of the workpiece].
Plasticization at 180-250℃ for 0-5 minutes, the post-heating plasticization process is most beneficial to obtain a smooth coating.
Cooling: Natural cooling or air cooling.
Health and Safety:
Powder coating is a non-toxic product, but it is important to avoid inhaling the dust during use. It is recommended for operators to wear appropriate dust masks and goggles.
Installing edge exhaust fans above the fluid bed is advised to prevent prolonged skin contact with the powder coating.
Note:
Only important for aesthetic reasons, but also for functional purposes.
A low film thickness can lead to various issues such as defects and roughness. It is crucial to ensure that the workpiece design is carefully considered to prevent these problems.
Sharp objects should be properly grounded to avoid any potential damage. Additionally, seamless welding is essential to maintain the integrity of the product.
The metal thickness and wire diameter inside the workpiece should be similar to ensure uniformity and stability.
By paying attention to these details, the final product will not only look visually appealing but also perform optimally.
