RHOPLEX™ 78 Acrylic Emulsion

An acrylic emulsion is designed as a binder for elastomeric wall coatings. The emulsion produces durable coatings with the excellent elongation and recovery characteristics necessary to bridge dimensionally unstable cracks. This product employs a chemistry that imparts excellent dirt pickup resistance. In addition to elasticity and durability, coatings based on the product are permeable to water vapor, which permits moisture in the masonry substrate to escape without causing blisters.
