1. Coating or contact with water or exposed to high temperature environment;
2, solvent evaporation is too fast, the viscosity of paint is too high;
3, mixing and mixing the paint gas is not released, as soon as the coating;
4, some solid substances in the coating will automatically decompose and emit gas, but the film is blistering.
1, coating in construction should not contact with water, wet coating should avoid long-term exposure to high humidity environment;
2, the use of solvent and diluent, coating viscosity should be moderate;
3, it is best to add alcohol solvent and defoaming agent.
4, after mixing the paint should be cured after a certain period of time and then construction.
