Advantages of Powder Coating
Strong Coating
Powder coating provides a durable finish that’s far stronger than what liquid paints offer. These coats are known to protect equipment in the harshest environments without compromising on the aesthetics of the finish. As a result, it’s common to find such coating used on large industrial equipment, structures, and oil field supplies.
Affordable
Powder coating is also affordable with the application process eliminating many extra steps and drying time that comes with liquid paint. The raw material powder is less expensive than wet paint and can be stored away in far less space than what traditional paint cans would need.
Various Colors And Finishes
Powder coating offers many colors and finishes. One can also easily have custom colors made by the manufacturer quickly, and there is a broad range of finishes from high gloss to matte. It’s even possible to customize the texture of the coat (e.g., texture or metallic).
Low Maintenancee
Powder coatings require little maintenance after application. Since the coating his highly durable and resistant to corrosion or scratches – there’s never a pressing need to use cleaning solutions or solvents to keep the surface in tip-top shape. Generally, you can expect to clean the applied coating only a few times a year.
Quick Application
Powder coating is applied using an electromagnetic charge. This means there’s no need to wait for the coat to dry before applying another layer while applying the coating. It can all be done in one go with very little waste creation.
Even Application
The application of powder coating also results in an even finished horizontal and vertical surface. This is due to the process of spraying and rapid heating to apply the powder coating. With liquid paint, you would run the risk of drips forming.
No Toxic Fumes
Liquid paints are known to release toxic fumes from volatile organic compounds into the air. With powder coatings, this risk is non-existent or very little, making it a far safer option to use.
Low Carbon Footprint
Powder coatings are also known to have a low carbon footprint throughout their value chain. This is great for businesses aiming to switch to more environmentally sustainable materials in their manufacturing process.
Recycle Friendly
Liquid paints commonly create unwanted waste that needs to be disposed of properly. Powder coatings, however, can be recycled and reused. This makes them a more environmentally friendly, cost-effective, and efficient coating to use.
Greater Transfer Efficiency
While liquid paint coats have a transfer efficiency of 30% and nearly half of the product evaporates away. With powder coating, you get a 65% transfer efficiency on average, with any overspray recovered to be used again in the future as needed.
The powder coating process starts with meticulously cleaning and pre-treating the metal surface for optimal adhesion and performance. Electrostatically charged powder particles are then sprayed onto the metal, adhering uniformly to its surface. The coated piece is then cured in an oven, where the powder melts and fuses to form a seamless, durable, long-lasting finish. This process increases the metal’s functionality and ensures a flawless visual appeal. Unlike liquid coatings, powder coatings are solvent-free, making them a more environmentally friendly choic
Types Of Powder Coating
Polyester Thermoset Powder
This type of thermoset powder is the most commonly used powder coating in Houston. Over 60 percent of the market uses polyester-based powder coatings because of its durability and ability to withstand constant outdoor exposure.
Epoxy Thermoset Powder
Unlike polyester, epoxy thermoset powder coatings in Houston do not hold up well outdoors. However, they are perfect for indoor industrial equipment, indoor metal furniture and elements, as well as automotive underbody components.
Acrylic Thermoset Powder
Acrylic thermoset powders in Houston are used mainly for clear coating over other materials and are often used in the automotive industry as they are chip resistant. Acrylic powders can also be added to polyester powders to improve the flow of the powder and the smoothness of the surface.
Raw materials for Powder Coating
Resins
Resins are the key component of powder coatings. The range of resins used is increasing steadily in an attempt to meet the more demanding needs of new market sectors. This component in the formulation will largely determine the processing and end-use performance properties of powder coatings. There are two main classifications for powder coatings: thermoplastic and thermoset. The final coating has a different chemical structure than the applied powder.
Thermoplastics powders
A thermoplastic powder coating melts and flows when heat is applied but continues to have the same chemical composition once it cools to a solid coating. They are typically high molecular weight materials that require high temperatures to melt and flow.
Considerations in Powder Coating
While powder coating has numerous advantages, there are practical considerations to keep in mind. Standard applications typically result in a coating thickness of two to four mils, which may require additional layers for specific project needs. The process also requires specialized equipment, leading to higher initial setup costs. Additionally, ensuring consistent color across batches can be challenging due to variations in production and curing conditions. However, these challenges can be addressed with proper planning and coordination.
