the adjustment of the proportion of diluent to adjust the paint construction viscosity, 9-11 seconds primer, NC head primer 9-14 seconds, PU second primer 14-16 seconds, NC second primer 15-18 seconds, PU finish 11-13 seconds, NC finish 10 -12 seconds. It should be noted, however, that if the ambient temperature is too high and the amount of diluent is not sufficient, it may ultimately affect the
quality of the film. Therefore, in the actual construction, should be pre-painted with the diluent ratio test to the film will not be ills for the premise of the ratio. 3, the thickness of the construction of the control of the summer coating construction, due to the high temperature, spraying should not be thick coating, because the paint solvent rapid evaporation, resulting in relatively fast surface dry, coupled with the spray
film and thick, so Easily lead to the surface of the paint film prickly heat, bubbles and pinholes and other ills, construction workers should take full account of climate factors, reasonable arrangements to avoid unnecessary problems. Summer construction prone problems problem reasons solution flat paint blistering workers in order to pursue a certain degree of fullness and fear of environmental particles fall in the
