Recently, the coating industry has achieved significant breakthroughs in anti-corrosion technology. A variety of salt spray resistant additives based on different chemical structures have gained market attention with their excellent performance. Through precise molecular design, these additives provide flexible and efficient salt spray protection solutions for coating formulations, effectively solving the corrosion protection problems of metal substrates and being widely applicable to industrial coating, equipment protection and other scenarios. According to the classification by chemical structure, the mainstream salt spray resistant additives currently mainly include six categories: amine derivative type, phosphate type, carboxylate type, azole compound, organotitanium and polybasic acid-amine complex. Among them, amine derivatives such as ASCOTEC ASCONIUM® series products form a protective film on the metal surface through amino functional groups, with both anodic and cathodic inhibition effects, simple addition process and significant improvement effect; phosphate salts are suitable for water-based systems, forming a stable protective layer through the complexation reaction between phosphate ions and metal ions, while having good wettability and dispersibility. The application flexibility of such additives is highly favored by the industry. In terms of addition amount, it accounts for 1.5%-3% of the total formula weight when used alone, and only 0.8%-2% when used in combination with other anti-rust pigments. Adding 2.5% can achieve the 500-hour salt spray test standard under a dry film thickness of 50 microns. Its applicable systems cover mainstream coating systems such as one-component/two-component acrylic, epoxy and polyurethane, as well as water-based and solvent-based alkyd systems, which can be flexibly added in the grinding and dispersing stage or after the paint mixing stage. With the continuous improvement of industrial anti-corrosion requirements, salt spray resistant additives are becoming a key link in the optimization of coating formulations. Insiders said that the technological innovation of these additives not only improves the anti-corrosion durability of coatings, but also expands the application boundaries of coatings in harsh scenarios such as marine environments and high-humidity working conditions, providing strong support for the quality upgrading of related industries.
