1 Viscosity

Before coating viscosity adjustment on the coating is very important, too high will cause the wet film is too thick, dry film wrinkle, leveling is not good, foaming, too low will cause film flow. In compliance with the manufacturers to provide the allocation than the standard, should also be adjusted according to the change of temperature in winter and summer, the best finish every time, to have dilute paint viscosity test, so that it can ensure the unification of each spraying viscosity.

2 Application period

Refers to the reactive coating can use time. Time to master the use of good paint is very important, the deployment of good paint, must run out in the application period, it can not be used or gel scrap. Usually before painting, first understand the selected paint the best applicable period, know yourself in this time period can apply for how much paint and then, finally decided to each equipped with much paint, especially applicable period of UPE coating and UPE coating is very short, after drying, on the appliance of the very good, very difficult to wash. Color matching principle is a small number of times.

3 Of the recurrent crude

Have good dispersion of the filler coating containing pigment, placed after a period of time, pigment, filler containing again after spraying coating, resulting in many particles on the surface, back coarse is generally paint their own problems, paint manufacturers the production process is not good or the use of substandard raw materials. In the process of painting and find back rough phenomenon, immediately stop the operation, the fineness of coating inspection. The situation is not serious, have to be film coating is dry, coarse, sandpaper to smooth can. But note that not every film surface found in coarse grain, immediately asserted that "return of crude".

4 agglomeration

The agglomeration phenomenon in the paint, because the paint is generally has undergone partial response and coatings used in a large number of unqualified silty, over the storage period, the production process problems and the formation of. Open tank inspection, coating paint caking phenomenon found should immediately stop the operation. To find out the causes and solutions to decide whether to continue to use, can be used manually or mechanically to have caking coating for mixing, such as lumps were scattered and dispersed uniformly, filtering, detection, try to spray are qualified, can be formally used.

5 Precipitation

Precipitation is generally the placed time is too long or paint system caused by the density of each material are not the same, the cause is a selection of raw materials, production process problems, over the storage period of the products are more likely to have this problem. In general, in addition to varnish the outer,
