Reasons why Chemtec One concrete sealing curing agent floor can be used for more than 40 years：

　　1、Weathering resistance test: 75 cycles of freeze-thaw, no spalling on the surface,(equivalent to more than 50 years of natural weathering.)

　　2、Wear resistance test: Wear resistance is increased by 45%, and the wear life of concrete is prolonged by one time.

　　3、Impermeability test: the coated concrete is improved by 2-3 impermeability grades.

　　4、Anti-carbonization ability is increased more than 3 times.(Carbonization performance test: carbonization in carbonization box for 60 days is equivalent to 50 years in natural environment)

　　5、Sealing performance test: Use 3000 times electron microscope to observe 5 mm inside the concrete，Pores and microcracks were sealed
