Primers

Example of a plaster with the primer underneath.

Primers are essential to ensure long-term stability of layered building systems. VINNAPAS® polymer dispersions provide excellent adhesion to a variety of substrates and act as excellent bonding agents.

VINNAPAS® | Construction Dispersions | An Overview PDF, 14.2 MB | English

In primers and bonding agents, VINNAPAS® dispersions contribute to the long-term stability of layered building systems. VINNAPAS® dispersions display excellent adhesion to a variety of substrates and good penetration into the surface. The result: The substrates are consolidated and the absorbency is controlled.

For open-pore substrates such as concrete, cement and gypsum plasterboards, VINNAPAS® dispersions with small particle sizes are available. For outdoor applications, hydrophobic VINNAPAS® dispersions are recommended, as they provide high water repellency and good barrier properties. In general, VINNAPAS® dispersions are suitable for formulating bonding agents with or without the use of aggregates / mineral fillers or co-binders such as cement.

Benefits:

  • Good consolidation of construction surfaces
  • Good to excellent penetration
  • Excellent adhesion to a variety of substrates and under all conditions
  • Improved abrasion resistance
  • Easy application

Applications:

  • Interior and exterior applications
  • Adhesion-promoting layer between subsequent layers
  • Construction surface consolidation
  • Barrier layer for migration protection
  • Impregnation of porous surfaces for protection and stain reduction

VINNAPAS® dispersions improve the properties of primers. Their excellent adhesion to a variety of substrates ensures optimal performance of the subsequent layers. Thanks to their excellent adhesive and cohesive properties, they also act as adhesion promoters.

For open-pore substrates such as concrete, cement and gypsum plasterboards, grades with small particle sizes are available. They ensure good surface penetration, which consolidates the substrate and controls the absorbency. In outdoor applications, hydrophobic VINNAPAS® dispersions provide high water repellency and good barrier properties.

Benefits:

  • Good impregnation due to deep penetration into the pores
  • Excellent barrier properties
  • Low and even absorbency
  • Good adhesion, also on critical substrates
  • Bridging of small cracks
  • Long open time

Applications:

  • Adhesion-promoting layer
  • Barrier layer for migration protection
