Water-based ,Solvent-based
The adhesion-promoting groups interact with the metal surface, allowing the promoter to orient effectively on the substrate, thereby improving adhesion.
Suitable for pre-coated panels that have undergone stretching, bending, or rolling.
Reduces corrosion at scratches, as observed after salt spray or water immersion tests.
Contains a high concentration of substrate-reactive groups that readily undergo cross-linking reactions with hydroxyl groups present in the coating system.
Suitable for coil coatings, can coatings, security door paints, automotive coatings, and other applications. Compatible with application methods such as spraying, dipping, and curtain coating. Effective in polyurethane (PU), acrylic, and epoxy-phenolic systems.
