Industrial-grade protective coating solutions: environmentally friendly, durable, and cost-effective.
Intro to Appliance Industry White Powder Coating
Appliance Industry White Powder Coatings are high-volume, cost-effective formulations specifically developed for major household goods, such as refrigerators, washers, dryers, and air conditioners. The core requirements for this application are consistent color matching (usually RAL 9010 or similar OEM whites), excellent surface finish, resistance to domestic cleaners, and superior adhesion and flexibility to handle the sheet metal fabrication processes. These are predominantly Hybrid (Epoxy-Polyester) or specialized low-yellowing Epoxy systems, chosen for their balance of performance, affordability, and efficient throughput in automated, high-speed production lines.
Color Stability and Fabrication Flexibility
The key performance criteria for appliance white is its color consistency and resistance to thermal yellowing. Since most appliances are white, any slight color shift during curing (overbake) is immediately noticeable. Hybrid systems are utilized to minimize this yellowing risk while providing the robust chemical resistance needed to withstand frequent cleaning with household products. Flexibility is also vital; appliance components often undergo post-coating assembly and forming operations (e.g., stamping, bending), and the coating must withstand these stresses without cracking, flaking, or loss of adhesion. The white finish also demands excellent flow and leveling properties to achieve the smooth, high-quality aesthetic expected by consumers. Furthermore, the high-volume nature of the appliance industry requires a powder that exhibits high transfer efficiency and excellent reclaiming properties to maximize material utilization and minimize operational costs on continuously running automated lines.

Frequently Asked Questions (FAQs)
- Q: Can this white powder be guaranteed not to yellow at all?
- A: While yellowing is significantly reduced, no white organic coating is entirely immune to thermal degradation, especially under extreme overbake. Hybrids offer the best balance, but critical applications may specify a Low-Temperature Cure system for absolute color assurance.
- Q: What film thickness is best for appliance white powder?
- A: A controlled film thickness of 60 to 75 microns is often optimal. Thinner films may not hide substrate imperfections, while thicker films increase cost and the risk of flow/yellowing issues.
- Q: Is the Appliance White formula suitable for exterior use?
- A: No. Appliance Hybrid systems contain epoxy and are not UV stable. For exterior AC units or shaded areas, a specific exterior polyester white would be required.
