Silicone acrylic emulsion, water, propylene glycol, coalescing agent, fungicide, PH regulator, polyurethane thickener in component C is successively added
To reaction kettle, 10-15min is stirred with the speed of 1200r/min, obtains continuous phase solution；
4) preparation of finished product paint
Color grain is made in step 2) to mix with the obtained continuous phase solution of step 3) by 3:2, is stirred evenly with glass bar or medicine spoon, i.e.,
Can there must be the fast-drying aqueous multicolor finish of excellent water-whitening resistance energy.
10. according to the preparation method for requiring the 9 fast-drying aqueous multicolor finishes is gone through, which is characterized in that continuous in the step 3)
The viscosity of phase solution is 85-110KU.
