BASF DETA Diethylenetriamine: Essential for Superior Metal Anti-Corrosion and Surface Treatment

Metal materials play a critical role in industrial processing, but their surfaces are prone to corrosion, oxidation, and contamination, leading to performance degradation or even failure. Therefore, metal anti-corrosion and surface treatment have become indispensable processes in industrial manufacturing. Through surface treatment, oils, rust, and oxide layers can be effectively removed from metal surfaces while forming a protective film to enhance corrosion resistance, wear resistance, and adhesion.

In industries such as automotive manufacturing, aerospace, construction, and electronics, the quality of metal anti-corrosion and surface treatment directly impacts product lifespan and safety. For example, in automotive manufacturing, anti-corrosion treatment of metal components significantly extends vehicle durability. In construction, steel structures with proper surface treatment exhibit superior resistance to environmental corrosion. Thus, selecting high-performance surface treatment agents and anti-corrosion additives is crucial for industrial processing.

Key Pretreatment Steps: Degreasing, Descaling, and Derusting

During metal surface treatment, degreasing, descaling, and derusting are critical preparatory steps. The addition of BASF's DETA (Diethylenetriamine) significantly improves the efficiency and quality of these processes. The amine groups in DETA react with oils and rust on metal surfaces, forming soluble complexes for easy contaminant removal. Additionally, DETA helps create a protective film on metal surfaces, enhancing adhesion for subsequent coatings or plating.
