What is concrete curing film?

Performances of concrete curing film

 Working principle

Core of the concrete curing film is the new controllable high polymer crystal material which stick on the film. The high polymer can absorb water that is as 200 times as its own weight and will turn into transparent gel after absorbing water. Thus the liquid water turns into solid water. One square meter of curing film can absorb about 0.5KG water, which forms a mini-reservoir on concrete surface. With the effect of capillary, the water will permeate through the concrete surface. Meanwhile, the polymer crystal will also absorb the evaporating water that comes out from the concrete continuously during the process of hydration. The curing film can keep the concrete surface wet during whole curing period.
