Definitions

  • the invention relates to the use of vinyl chloride-ethylene copolymers for imparting water repellency to construction materials, especially for surface-coating materials such as skim coats, monocouche coatings and joint fillers.
  • Polymers based on vinyl ester, vinyl chloride, (meth)acrylate monomers, styrene, butadiene and ethylene are employed in particular in the form of their aqueous dispersions or water-redispersible polymer powders in numerous applications, for example as coating materials or adhesives for any of a very wide variety of substrates. These polymers are stabilized using protective colloids or surface-active compounds of low molecular mass.
