Fluorocarbon PVDF Surface Treatment Technology

Detailed explanation of aluminum alloy surface treatment technology: powder spraying, fluorocarbon spraying and wood grain treatment

Aluminum alloy surface treatment technology determines the product life and beauty: powder spraying forms a corrosion-resistant polyester layer, fluorocarbon spraying creates a weather-resistant metallic luster, and wood grain transfer achieves exquisite texture. Different processes have their own advantages, from acid and alkali resistance to UV resistance, and the choice determines the ultimate performance and value of aluminum.

Fluorocarbon spray profiles

Fluorocarbon spray technology uses electrostatic liquid spraying to create high-performance coatings through two, three or four-layer processes, of which two and three layers are the most common. The process includes: chemical pretreatment, primer electrostatic spraying, leveling, topcoat electrostatic spraying, re-leveling, varnish electrostatic spraying, and finally baking and curing. The fluorocarbon coating used in this technology uses polyvinylidene fluoride resin (PVDF) as the main component and is synthesized with metal powder to give the coating a metallic luster. Fluorocarbon spraying forms a UV-resistant and corrosion-resistant coating through a multi-layer process.
