Why should polymer mortar be used for exterior wall insulation of integrated board?

Polymer mortar refers to polymer cementitious materials. Polymer cement mortar is obtained by uniformly mixing polymer into cement mortar. It is a new type of concrete surface repair and reinforcement material. It has the characteristics of high bonding strength, small shrinkage deformation, low compression modulus and strong corrosion resistance of chloride ions and sulfate ions, which can significantly improve the corrosion resistance of steel bars and has certain shrinkage compensation performance, and the price is lower than that of similar products.
