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 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 …

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 …

In the realm of modern industrial coating, powder coatings are steadily becoming the preferred choice due to their eco-friendly, solvent-free characteristics. The particle size distribution of powder coatings is a core technical indicator that directly affects the appearance, performance, and application results of the coating. This article delves into the importance of particle size distribution in powder coatings, measurement methods, and how to enhance their performance through optimization strategies. Introduction The particle size distribution of powder coatings is a criticalRead More …

The quality control of powder coatings is a key link to ensure the performance and appearance of the final product. Here are some steps and methods to ensure the quality control of powder coatings:   1. Raw material inspection: All raw materials are strictly inspected for quality to ensure that they meet the specified standards and specifications.   Check the purity, particle size distribution, color and chemical stability of resins, curing agents, pigments, fillers and additives, etc.   2. ProductionRead More …

In the realm of industrial finishing, powder coating stands out as a versatile and eco-friendly solution that offers a durable, high-quality finish. The success of your powder coating project hinges largely on the quality of the powder itself. Selecting the right supplier for your powder coating powder is a critical decision that can impact the performance, appearance, and longevity of your products. This blog post aims to provide you with a comprehensive guide to choosing the best powder coating powderRead More …

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 …

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 …

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 …

Powder coating sagging refers to the uneven flow of powder on the surface of the coated part during the coating process, forming a sag or sagging phenomenon. Sagging may cause problems such as uneven coating thickness and poor surface quality. The following are some reasons that may cause powder coating sagging: 1. Properties of powder coating: -High viscosity: High viscosity of powder coating may lead to poor fluidity and increase the risk of sagging. -Excessive particles: Excessive particles may makeRead More …
