Assessing the Adhesion of Powder Coatings: A Comprehensive Guide
Ensuring the adhesion quality of powder coatings is crucial for long-term performance and durability. Here’s a look at various methods to evaluate the adhesion of powder coatings, which are essential for quality control in industrial applications. Cross-Hatch TestThe cross-hatch test, is a widely used method for assessing adhesion. It involves cutting a grid pattern of small, intersecting cuts into the coating. Adhesive tape is then applied over the cuts and quickly pulled off. The coating’s resistance to peeling off atRead More …
FBE Powder Coatings: Exceptional Adhesion in High-Temperature Environments
Fusion Bonded Epoxy (FBE) powder coatings are renowned for their superior adhesion, particularly in high-temperature applications. This characteristic makes them a preferred choice for numerous industrial uses where coatings must withstand the rigors of elevated temperatures. Adhesion at High Temperatures Chemical Bonding: FBE powder coatings form a robust bond with metal surfaces through a chemical reaction that occurs when the coating melts. This chemical bonding mechanism ensures that the coating maintains excellent adhesion even in high-temperature conditions. Heat Resistance: FBERead More …
Powder coating recycling: dual benefits of environmental protection and economy
Powder coating has been widely used in the field of industrial coating due to its solvent-free, low VOC emission, high utilization rate and excellent coating performance. However, a certain amount of overspray powder will inevitably be produced during the spraying process. If these powders are not handled properly, they will not only cause resource waste, but also affect the environment. Therefore, the recycling of powder coating is particularly important. This article will explore the methods, costs, and environmental and economicRead More …
