NORDPUR ESTERNI ADS

Textured polyurethane coating

Description

NORDPUR ESTERNI ADS is a three component product:

  • component A:      a mix of functionalized  prepolymers, pigments and additives;
  • component B:      prepolyisocyanate;
  • component C: fillers mix.

Once mixed, the three components produce a  flexible and highly adhering material that, applied to various surfaces, will provide a textured coating with very good abrasion resistance.

The product is available in three standard colours, white, red and grey (plus others on request) that do not significantly alter in time.

 

Range of use

NORDPUR ESTERNI ADS is used as a protective layer for outdoor surfaces, especially concrete. It can also be used on metal surfaces and ceramic tiles. 

Packaging

NORDPUR ESTERNI ADS is available in 9.7 kg packs.
