    摘要: Mortar formulations comprising a hydraulic cement and a PVOH stabilized acrylic latex or a spray dried redispersible powder made from the PVOH stabilized acrylic latex are disclosed. These include formulations suitable for use as tile mortars, patching mortars, EIFS base coats and grouts. An acrylic latex that, when formulated with hydraulic cement, has performance advantages over other latex resins in mortar, patch and exterior insulation and finishing systems. The spray dried, redispersible acrylic emulsion polymer that, when formulated with hydraulic cement, has comparable or better performance than a liquid latex in mortars and patches.
