What are the effects of low temperature on epoxy floor coating construction? Personnel engaged in this work should be aware that the best application environment of epoxy floor coating is the temperature of 10-35 C, humidity less than 75%. Usually the temperature of 5 C can also be used, but below 5 C, the actual effect of epoxy floor coating construction can not be guaranteed. In the low temperature environment, why is epoxy floor coating difficult to construct? The reasons for epoxy floor analysis are as follows: 1、降低涂膜质量
1, reduce coating quality.
Because the curing reaction is slowed down or the curing can not be completed, the film strength, wear resistance and hardness will be reduced, and more likely to occur floor disengagement and other phenomena, which seriously affects the life of the epoxy floor.
2, slow down the paint reaction.
In the construction of two-component floor coatings, it is necessary to mix the two groups according to the ratio of 5:1 or 1:1, mixing evenly, so that the two components can react sufficiently, so as to ensure the construction effect of epoxy floor coatings. However, if the temperature is lower than 5 C, the two-component reaction will decrease or slow down, which seriously affects the solidification of floor coatings. Yes.
Epoxy floors show that a decline in curing performance can cause the film to dry very slowly and increase the possibility of contamination by dust, insects (such as mosquitoes, flies) or debris.
3. Viscosity increases exponentially.
Self-leveling coatings without solvents do not require scraping, but only rely on leveling to ensure the smoothness of the epoxy floor, but at low temperatures, the viscosity of the floor coatings will increase exponentially, leveling performance will continue to decline, and no leveling coatings, in the scraping process due to flow, leveling performance will deteriorate. And there are defects in the trowel marks.
