Application reference

1. CM 5233 is a secondary dispersion, and color paste can be directly added during paint production;

2. CM 5233 can be used in conjunction with curing agents from most manufacturers such as Wanhua;

3. The paint film prepared with CM 5233 can self dry at room temperature or be baked at low temperature, and the recommended baking temperature should not exceed 80 ℃;

4. Recommended solvents: BCS，DPNB , DPM;

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.

Reference formula and instructions for water-based dispersion baking paint (white)

1. Substrate: tinplate, baked at 150 ℃ for 30 minutes

Process description: 1 Put 1-5 into the sand mill in order to grind evenly, grind the fineness to below 20 μ m, filter out and set aside for later use.

2. Disperse 6-12 evenly in order to make clear varnish

3. Pour the prepared slurry into the varnish, stir evenly, and then package it.
