ZX-Ⅱrelease agent is a new type of concrete demoulding agent consists of organic polymer and chemical auxiliary agents and other materials. The product is of great convenience in construction and is easy to dissolve in water. A layer of smooth isolating membrane will be formed after painting the product dissolved in water to the template. The membrane may prevent the concrete from contacting the template directly and completely, which also apply to the bubbles. The bubbles at the contact area between concrete and template overflow rapidly in case of concrete pouring, so that the surface of concrete after demoulding is smooth and beautiful and free from pore.
