Determining Whether Powder Coating Is Waterproof
Is powder coating waterproof? With companies in multiple industries relying on powder coating to protect metal surfaces, you may be wondering whether it’s suitable for your applications, in terms of being waterproof.
Yes, indeed, powder coating is waterproof, making it an excellent option for protecting metal surfaces exposed to moisture. This is the case whether you are working with heavy construction equipment or metal surfaces in the military sector.
What Is Powder Coating?
The process involves electrostatic application of dry powder to the metal surface you need to protect. Then it is cured at a high temperature to melt the powder so it fuses to form a hard, durable and uniform layer. When done correctly, powder coating forms a seamless, impermeable barrier, which ensures water cannot penetrate the metal surface.
It’s a better option when compared to standard industrial spray-painting, especially when you need coverage in areas that are difficult to reach.
Is Powder Coating Waterproof?
Yes. Powder coating is highly waterproof. The curing process in powder coating creates a reliably consistent, protective layer that seals the metal, keeping out water. This characteristic makes powder coating particularly effective in environments exposed to moisture, such as outdoor or industrial settings.
Benefits of Powder Coating in Wet Environments
Here are seven key benefits of powder coating in wet environments.
- Durability: After you protect a metal surface with powder coating, it will resist chipping, scratching, and wear. Doing so provides a better return on your investment. In contrast, keep in mind that standard spray-painting treatment often results in chipping when exposed to hot and dry environments.
- Reuse and Recycle: If you overapply the powder during the application process, you can recover it and recirculate the powder later to avoid wasting materials.
- Waterproof Protection: Whenever you work with metal surfaces in moist environments or when there is a potential for water to contact your metal (such as during major weather events), you can rest assured that this process will protect these surfaces against rust, corrosion and water damage.
- Safeguard Employees: The nonflammable powder used in powder coating processes is free of volatile organic compounds (VOCs), which results in a safer working environment for your team.
- Chemical Resistance: In addition to being waterproof, powder coating resists chemicals. It’s a suitable option to protect metal surfaces that might connect with damp items.
- Aesthetic Appeal: Powder coating offers a range of colors and finishes for beautifying metal surfaces while protecting them.
- Cost-Effectiveness: It’s true that powder coating typically involves higher up-front costs, but the expenses are offset by its long-lasting protection with relatively less maintenance. You can anticipate saving money because you reduce the need for repairs or replacements.
Limitations of Powder Coating in Wet Environments
Although powder coating is an outstanding solution for waterproofing applications, there are some limitations to consider.
Vulnerability to Damage: Manufacturers use powder coating to make metals resistant to chipping and scratching. But if chips or scratches do occur, water can seep through, resulting in rust. Accordingly, you’ll need to frequently examine protected surfaces to ensure their integrity.
Surface Preparation: You must prepare your surface properly. Otherwise, water trapped below your powder coating may reduce adhesion, minimizing its waterproofing performance.
