The optimum environmental temperature for epoxy floor paint construction is 10-35 C, too low or too high temperature will have a negative impact on the construction of epoxy floor paint, can not guarantee the effect after construction. The following epoxy floor paint manufacturers will give you an analysis of the impact of too low or too high temperature on the construction of epoxy floor paint. If the temperature is higher than 30 degrees, the consistency of the coating will increase, the dry end will be scrapped, and if serious, the explosion will occur. The influence of high temperature on the construction of epoxy floor paint leads to the fact that workers can not finish the construction of floor paint materials in barrels, and floor paint is no longer useful. Generally, we use a small number of times to prepare the paint, or choose a diluent with high boiling point and slow volatilization to adjust the influence of temperature on the construction of epoxy floor paint.
I. Effect of Low Temperature on Construction of Epoxy Floor Paint
1. Slow down the reaction of paint.
In the construction of two-component floor paint materials (our company's two-component), it is necessary to mix components A and B at a certain ratio on site, mix evenly, and make the two components react fully, so as to ensure the effect of the floor. However, if the temperature is lower than 5 C, the reaction will be reduced or slowed down, which will seriously affect the curing performance of floor coatings. Decreased curing performance will result in a slow drying of the film surface, which will increase the possibility that the film will be contaminated by dust, debris, or insects (flies, mosquitoes).
2. Viscosity doubles.
Solvent-free epoxy self-leveling floor coating does not need to scratch, depending on leveling to ensure the evenness of the floor. However, at low temperature, the viscosity of the floor coating will be doubled and the leveling performance will be reduced. However, without leveling coating, the defect of trowel marks will appear when scraping because of the poor flow and leveling performance.
3. Reduce the quality of the film.
The strength, hardness and wear resistance of the coatings will be reduced due to the slow curing reaction or the failure of curing, and the problems of epoxy resin floor detachment will occur more easily, which will seriously affect the service life of the epoxy floor paint.
