Reference formula and instructions for water-based red hydroxy acrylic topcoat
1. No anti rust pigment filler, substrate: tinplate/cold-rolled sheet; After drying for 2 days and baking at 80 ℃ for 3 hours, various indicators were tested.
Process description:
1 Put 1-8 into the dispersing cylinder in order and stir at high speed to disperse evenly.
2. Grind the above materials with a sand mill and control the speed and temperature. The temperature should not exceed 50 degrees Celsius. Grind them to a fineness of less than 20 microns before proceeding to the paint mixing process.
3. In the paint mixing process, add 9 and 10 in sequence and stir evenly. Add 11 and 12 to adjust the viscosity, then add 13 and stir evenly before packaging.
