Polymer powders: Crucial Ingredients for Perfect Results

Traditional cement mortars have difficulty coping with the many different demands of modern construction technology.

The simple reason for this is that conventional cement mortars bond by mechanical interlocking with porous substrates.

Today, however, neither the tiles nor the substrate are sufficiently porous for this type of installation. Beginning in the 1950s, liquid polymer binders were added to mortars to improve the bond strength. Unfortunately, these liquid additives proved awkward and difficult for the installer to handle.

In 1953, WACKER developed the first polymer binders in the form of dispersible polymer powders.

These dispersible polymer powders form the ideal complement to mineral binders such as cement. This combination yields a mortar with outstanding synergistic properties and characteristics that a single binder cannot offer on its own.

Moreover, these polymer binders can also be added in precisely metered amounts during factory pre-mixing of the dry-mix mortar. A pre-mixed mortar is then delivered to the building site, and only needs to be mixed with water. These polymers modified, one-component systems decisively improve the handling and reliability of the adhesive mortars.

VINNAPAS® dispersible polymer powder improve properties such as:

  • Adhesion
  • Flexibility (plasticity)
  • Workability
  • Wetting
  • Non-slump
  • Open time
