Concrete curing agent, also known as concrete protective agent or concrete curing liquid, is a new type of polymer formulation prepared using modern high technology. It is a liquid film-forming compound with a wide range of adaptability. The product is water-based, non-toxic, non flammable, and easy to use. When sprayed on the surface of concrete or mortar, this curing agent can quickly form a colorless, impermeable film when the water evaporates to a certain extent, which can prevent the evaporation of water in concrete or mortar, reduce concrete shrinkage and cracking. One ton of curing agent can save 2000 tons of water.
