These parameters highlight the coating’s reliability: a thermal decomposition temperature above 380℃ ensures safety under extreme heat, while a Shore D hardness of 75 and low abrasion loss (5-9 mg/1000 cycles) guarantee resistance to physical wear from repeated use. The low moisture content (≤0.1%) also prevents powder agglomeration, maintaining consistent quality during storage and application.
4. Application Methods of Fluorocarbon Powder Coating for Electroplating Racks
To achieve optimal performance, proper application of Fluorocarbon Powder Coating for Electroplating Racks is essential. Follow these steps for best results:
1. Recommended Application: This product is primarily designed for fluidized bed dipping. If electrostatic spraying is required, please contact our company to obtain the appropriate powder formulation.
2. Substrate Preparation: Before coating, thoroughly remove oil and rust from the electroplating rack surface. This step ensures strong adhesion between the coating and the rack, preventing peeling or cracking.
3. Substrate Preheating: Place the rack in an oven and preheat it until the entire component reaches a uniform temperature of over 250℃. Adjust the preheating temperature based on the rack’s heat capacity, size, and shape—smaller or thinner parts require higher temperatures due to faster heat dissipation.
4. Powder Application: Immediately remove the preheated rack from the oven and apply the powder coating (via fluidized bed dipping or electrostatic spraying, as selected).
5. Curing and Finishing: After application, return the rack to the oven for baking until the coating surface levels out. For thicker coating layers, repeat the dipping process; otherwise, cool the rack to form a solid, even protective film.
5. Packaging and Storage of Fluorocarbon Powder Coating for Electroplating Racks
Proper packaging and storage are crucial to preserving the quality of Fluorocarbon Powder Coating for Electroplating Racks:
• Packaging: The product is packaged in 25KG barrels, which are designed to prevent contamination and facilitate easy handling during transportation and use.
• Storage Conditions: Store the barrels in a cool, well-ventilated area. Avoid exposure to direct sunlight, high temperatures (exceeding the coating’s maximum service temperature of 150℃), and water immersion. Improper storage can lead to powder agglomeration or chemical degradation, which may compromise the coating’s performance during application.
