Advantages and disadvantages of organic solvent coating and water dispersion coating processes

1, advantages: the water dispersion avoids the problems of flammability, explosion and environmental pollution in the organic solvent coating process, and has high solid content, low viscosity and short process cycle. Generally, the solid content of coating liquid coated with organic solvent is not high, which leads to long coating time and long production cycle.

2. Disadvantages: organic solvent coating: poor safety, high toxicity, expensive solvent recovery equipment, low polymer solid content in coating solution, high viscosity, long coating time and high energy consumption.
