Because epoxy floor paint has excellent wear resistance, pressure resistance, overall seamless, colorful, easy to clean and other characteristics, many underground parking lots will choose to do epoxy floor paint, not only can effectively distinguish parking lanes, parking spaces, walkways and other areas, but also can improve the overall property grade. Since epoxy floor paint is very suitable for parking lot, is it suitable for outdoor parking lot to make epoxy floor paint? Although epoxy floor paint is widely used and popular with owners and customers, its weatherability is very poor. Outdoor sunshine exposure, rain erosion and soaking will make the epoxy floor fade gradually, and even make the epoxy floor film crack. Therefore, the construction of epoxy floor paint is not recommended in outdoor parking lot. The main reasons are as follows:
1. The weatherability of epoxy resin is very poor. Epoxy resin is composed of at least two epoxy groups. The chain of epoxy group is easy to break under ultraviolet radiation, resulting in powdering of resin film, so epoxy anti-corrosion products can not be used for outdoor protection.
2. Epoxy paint has excellent physical and mechanical properties, the most prominent is its strong adhesion to metals; its chemical and oil resistance is also very good, especially alkali resistance is very good;
3. Epoxy paint has strong adhesion, tough film, excellent alkali resistance, good insulation and chemical resistance. However, the curing rate is slow, and it is easy to pulverize when used outdoors.
4. Epoxy flooring has poor weather resistance and is prone to color change when exposed to ultraviolet radiation. It is widely used in various industrial plant floors.
Therefore, for outdoor parking lot Guanglei floor paint manufacturers suggest to do polyurethane floor or acrylic floor. Polyurethane floor paint and acrylic floor paint have good weatherability, can withstand the outdoor wind and sunshine, the common basketball court, volleyball court and other outdoor floor with acrylic floor paint.
