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 …

How to Handle Contaminated Powder Coatings?

Powder coatings are widely used in various industries due to their durability, environmental friendliness, and cost-effectiveness. However, contamination can occur during storage or application, which can compromise the quality and performance of the coatings. This article provides detailed guidance on handling contaminated powder coatings, ensuring that they can be restored or disposed of properly. Identifying the Type of ContaminationThe first step in dealing with contaminated powder coatings is to identify the type of contamination. Common contaminants include dust, oil, moisture,Read More …

Flame retardant for powder coatings

Flame retardant thermosetting powder coatings are mainly made by adding 1-10% of the total amount of flame retardant to conventional cyclopolymer powder coatings or polyester powder coatings, taking the flakes extruded from the extruder for direct combustion to determine the oxygen index, and evaluating it with reference to GB 2406-1993. And refer to GB 14907-2002 to determine the fire resistance. The conditions that flame retardants should have: High flame retardant efficiency, no or slightly lowering the original physical, mechanical andRead More …

Types of powder coating dispersants

Powder coating dispersants are a type of dispersant used to assist pigments and fillers in powder coatings. Its function is to evenly disperse solid particles into liquid media to ensure that the powder coating has good rheology, stability and uniformity. There are many types of powder coating dispersants. Several commonly used powder coating dispersants are introduced below. Organic solvents: Organic solvents are a common powder coating dispersant. It can interact with powder particles to help disperse the particles. The selectionRead More …

Color difference standard of powder coating

The color difference standard of powder coating can be divided into two common standards, namely △E and NCS standards. △E is an international color difference standard, which indicates the color difference between different samples. The lower the color difference value, the smaller the color difference between samples and the more similar the colors. The NCS standard is a color standard system developed by the Swedish Color Association (The Natural Colour System). It divides colors into 6 basic colors and 15Read More …
