A final note on epoxies is that many primers are epoxies due to their adhesion strength and corrosion resistance. Both TGIC and TGIC-free polyesters offer good mechanical resistance, including great flexibility and impact resistance, and good chemical resistance. They can also give a higher first pass transfer efficiency, but are more sensitive to excess film thickness and provide less overbake resistance than TGICs. Learn more. What is the difference between discrete and continuous variables? The Powder Coating Process Powder coating is one of the most durable finishes that can be applied to industrial manufactured products, and offers excellent corrosion protection and is very safe because of its lack of volatile organic compounds. Once the powder is applied the parts are cured in an oven, which melts and cross-links the powder over the surface of the part and creates a tough, scratch resistant and beautiful finish. The … Hybrids can be used in some of the same areas that epoxies are used, but are typically found on indoor appliances and other household items like furniture, shelving, interior lighting, and power tools. Not only is their color and gloss protection better, but they also provide better humidity and corrosion resistance. The various powders used in the powder coating industry have different characteristics that make them ideal for different applications. Powder coating allows for much thicker coatings than liquid paint, without running or sagging. They weather poorly and will often start to degrade on the surface after a few months. External Liquid Coating. The two most common types of Fluoropolymers found in powder coatings are FEVE and PVDF. A powder spray gun is used, which when triggered gives an electrostatic charge to the powder particles passing through it. FEVE resins are the most popular within the powder community for their superior one coat capability and incredible exterior performance. As the parts to be coated are grounded, the powder is attracted towards the part via the electrostatic process. They are designed to hold their color and gloss to within set limits for 5 to 10 years more when compared to a standard polyester. DO 178B - What is the difference between review and verification? Powder coating was developed in the 1940s, where volatile organic compounds or polymers (also called macromolecule) were spayed in a powder form on a metallic base. This low-temperature requirement makes it better for sensitive items. One draw of this powder is its low cure temperature. Powder coating is a finishing technology where adecorative and highly protective coating can be applied to a widerange of products. As an advanced method of applying a protective and decorative finish to a metal surface, powder coating is beneficial for individual consumers and heavy industry. And that’s before we even get to the thousands of colors and special effects available!
