VINNAPAS CEF 52 can be used as a binder for coating systems containing an opacifying pigment, such as polymer-modified plasters. The special composition and manufacturing technology mean that VINNAPAS CEF 52 can be used to formulate very hydrophobic products. VINNAPAS CEF 52 has only a slight intrinsic odor. It forms a film that is characterized by very low water uptake and good saponification resistance. To achieve optimum weatherability in pasty plasters and facade coatings, only use opacifying pigments in adequate quantities. VINNAPAS CEF 52 is highly suited for use as sole binder. The dispersion, however, can also be used to modify inorganic binders, such as cement and lime, improving their tensile adhesive strength, flexural strength, deformability, abrasion resistance and processability.
