Traditional powder coating is mostly limited to single metal substrates, while modern industrial products adopt more and more composite materials such as plastic-metal, wood-metal and fiber composite boards. Different substrates have inconsistent thermal expansion coefficients and surface properties, leading to poor powder adhesion and easy peeling. This article analyzes the coating difficulties of different composite substrates, summarizes targeted pretreatment processes and formula matching schemes, and solves common defects such as poor adhesion, blistering and cracking of composite substrate coatings.
READ MORE Many enterprises face blind selection problems when purchasing powder coatings, resulting in mismatch between powder performance and application scenarios, excessive cost waste or insufficient protective performance. This article summarizes a complete set of industrial powder coating selection guidelines, classifies and explains the applicable scenarios of epoxy, polyester, hybrid and functional powders. It matches targeted powder types according to different use environments such as indoor, outdoor, high temperature, humid and corrosive scenarios, helping enterprises select high-cost-performance powder products accurately and avoid quality risks and cost waste.
