Waterborne epoxy floor paint uses water as solvent. It is especially suitable for basement, warehouse and parking area with high groundwater level or without waterproof layer. It can effectively solve the foaming problem of common epoxy floor paint coating on wet ground. So what is the principle of waterborne epoxy floor paint to prevent blistering? The following Guanglei floor paint manufacturers will give you a detailed introduction. For ordinary epoxy floor paint, there are many reasons for foaming, but they are all the same principle, that is, there is water under the epoxy floor paint, which is caused by expansion when the temperature is higher. The main source of moisture is the dehydration of the ingredients of base and epoxy floor paint or the construction, of which the moisture content of base is the largest. The common floor paint film is compact and can not escape through the paint film after moisture evaporation on the base surface, thus forming the pressure on the top and causing the blistering of the paint film. Because water-borne epoxy floor paint uses water as solvent, there are fine pores in the cured film. Water vapor in the base can escape through these pores, which can relieve the pressure caused by vapor evaporation on the base and effectively prevent the foaming of the floor paint coating.
The difference between waterborne epoxy floor paint and common epoxy floor paint is as follows:
1. Different solvents. Dilution with water instead of solvent is the biggest difference between waterborne epoxy floor paint and solvent-based epoxy floor paint.
2. Component differences. Solvent-based epoxy floor paint is composed of resin, curing agent is modified amine, while water-based epoxy floor paint is just the opposite.
3. Performance differences. The shrinkage of waterborne epoxy floor paint is relatively strong. It should be scraped as thin as possible and not spread, otherwise cracking will occur.
4. Others. Waterborne epoxy floor paint requires a high agitator. It needs a toothed disc agitator with high power and fast speed.
