NORDPUR ESTERNI

Outdoor solvent based coating

Description

NORDPUR ESTERNI is a bicomponent product made up of :

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

The two components, once mixed together, produce a  flexible and highly adhering material. When applied to various surfaces, this provides a smooth covering with weather and abrasion resistance properties.

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

Usage field

NORDPUR ESTERNI is used as a protective layer for outdoor surfaces, especially concrete.

It can also be used on metal surfaces and ceramic tiles. The product is particularly indicated for stadium terraces.

Packaging

Available in 9 kg packs.
