Metal surface treatment agent is a halogen-free hardware treatment agent. It is used to enhance the adhesion of UV metal. Its function is to connect the upper and lower parts, making it hinge on the substrate and UV to achieve adhesion. Jiongsheng metal surface treatment agents are widely used in various zinc alloys, magnesium alloys, stainless steel and other hardware as well as water-plated parts or vacuum coatings. The resin has good affinity and does not peel off the paint when tested in hundreds of grids or boiled water. Construction process: 1. Coating process: Clean the surface of the hardware workpiece → spray metal surface treatment agent → dry at 60 degrees for 5-10 minutes → spray UV varnish → IR leveling (60±10℃×4~6min) → UV Curing (700±100mj/cm2) → Inspection, finished product 2. Construction viscosity: 8.5 seconds (Iwata 2# cup) 3. Construction air pressure: 3-4Kg/cm2 4. Spraying film thickness 6-8 microns. UV topcoat spraying film Thickness: 8-12 microns. Adhesion is better in this film thickness range
