          5d

          Temperature between 5-10 can be 842 epoxy cloud iron antirust paint construction, but the curing speed is very slow

          When the temperature is lower than 5 , it is not suitable for epoxy resin and curing agent to stop. In this case, the construction can be carried out in a paint shop where the temperature is higher than 5 C. Or use 842 (winter type) epoxy cloud iron antirust paint

          • Adequate ventilation is required during the construction and curing of the 842 Epoxy Antirust Paint

          842 epoxy iron oxide antirust paint in the paint surface is not chalk or other substances pollution, generally not the longest painting interval restrictions. However, when the paint is fully cured before painting the next road paint, you will get the best interlayer adhesion. If the paint film of 842 Epoxy Anticorrosive paint is exposed to atmospheric environment for a long time before coating the next painting, special attention should be paid to the cleaning of the surface of the paint film and the removal of the powdering layer by sanding in order to obtain good adhesion. Focus

          • If the coating thickness is too thick, such as 842, or if the relative humidity is greater than 85% during painting, the film will have a smooth surface. Before the construction of the next road finish, sanding with sandpaper to increase the adhesion between the paint film

          Statement The above data and data are based on our test and practical experience in the use of accumulated and can be used as construction guide. We do not understand the situation in the construction, we only guarantee the quality of the paint itself, other issues will not be responsible. For this manual, we will be based on the continuous improvement of products have the right to modify.
