The obvious advantage of epoxy resin floor paint is that it can be applied on a large area on site, and the whole is seamless. This has high requirements for the linear shrinkage rate of the coating film. The following should be paid attention to in production and deployment:
1. The effect of high oil absorption filler and low oil absorption filler on the shrinkage rate of epoxy self-leveling floor paint coating.
2. The effect of barium sulfate filler with low oil absorption on the shrinkage rate of epoxy self-leveling coating film is less than that of light calcium carbonate with high oil absorption, so choosing some fillers with low oil absorption to prepare epoxy self-leveling floor coating will Get a better coating effect.
In summary, it can be seen that barite powder and quartz powder fillers are superior to general calcium carbonate fillers in many aspects, and the performance of epoxy resin self-leveling floor paint has been significantly improved in all aspects, which has the following advantages:
1. The amount of filler added is greatly increased without significantly increasing the viscosity of the coating to ensure good leveling of the coating during construction.
2. Adding fibrous geometric structure powder can significantly reduce the linear shrinkage of the coating film and improve wear resistance.
3. The filler is well compatible with resin and other materials, and does not affect the chemical resistance and other comprehensive properties of the coating film.
