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 alt spray corrosion is the most severe industrial corrosion form, widely existing in coastal areas, chemical plants and marine engineering environments. Ordinary powder coatings are prone to blistering, rusting and peeling in high-salt fog environments. This article deeply analyzes the salt spray corrosion penetration mechanism of powder coatings, summarizes the failure causes of coating films in salt spray tests, and proposes multi-dimensional optimization schemes including formula upgrading, pretreatment standardization and film thickness control. It guides manufacturers to greatly improve the salt spray resistance of powder products and meet heavy-duty anti-corrosion engineering standards.
