Epoxy paint has 2 main types: water-based paint and solvent-based paint. But not everyone knows the difference between these two paints. So what is the difference? Let APT helps investor and contractor find out in the article below:
Moisture sensitivity of water-based and solvent-based paints
If solvent-based paint can only be applied to concrete floor with moisture content less than 6%, a water-based paint can be applied to floor with humidity up to 18%. Water-based paint is easy to use for floor with high humidity due to reverse osmosis or not lined with silver when pouring concrete.
This is a remarkable difference of water-based paint line compare to solvent-based paint. Constructor is completely assured when applying in low humidity locations such as basements, clean rooms.
VOCs content in water-based and solvent-based paints
VOCs are organic substances in solid or liquid form that can evaporate naturally when exposed to atmospheric pressure at normal temperature. The lower the VOCs content, the faster the paint dries and fewer odors are generated.
Water-based paint has much lower VOCs than solvent-based paint. Therefore, water-based paint smells less, environmentally friendly in the construction process.
Abrasion of water-based and solvent-based paints
If water-based paint has abrasion resistance of 0.63mg/cm2, solvent-based paint has extremely good abrasion resistance of 1.71mg/cm2. This makes the coating of solvent-based paint more durable than other paints.
Colors after application of water-based and solvent-based paint
Water-based paint contains water component so creating a shaded color. In contrast, with the chemical composition, containing solvent, solvent-based paint gives the concrete floor a shiny protective layer.
Construction techniques of water-based and solvent-based paints
As judged by experience contractors, solvent-based paint is easier to apply than water-based paint. Because water-based paint requires longer mixing and stirring time to create a link between Part A and B. Moreover, the drying time of solvent-based paint is faster than water-based paint. If the minimum time required to apply the next coat of solvent-based paint is 12 hours, the constructor must take at least 24 hours to apply the next layer with water-based paint.
Although there are many differences advantages, but in general both types of paint have good adhesion and chemical resistance.
