The above information is provided for reference only. Due to variations in formulations and raw materials, testing is recommended to verify suitability and feasibility.
Features:
It can directly bond with metal and plastic substrates, enhancing adhesion performance. It provides excellent adhesion improvement on aluminum, cold-rolled steel, galvanized steel, electroplated substrates, and other surfaces, including maintaining adhesion after water immersion and condensation tests. It also demonstrates excellent adhesion performance on engineering plastic substrates.
It is mildly acidic and provides a certain catalytic effect. In baking coating systems, it can catalyze amino resin crosslinking and partially replace or reduce the amount of acid catalyst used in formulations.
It improves coating film flexibility and corrosion resistance while significantly enhancing film hardness.
It offers excellent storage stability without causing thickening, gelation, or other storage-related defects.
