Polyurethane system SPU “Korund 1010“

TU 2254-007-02748978-2004

Two-component PU system based on Korundinol 1010 (Component “A”) andKorundinat PM” (Component “B”) is designed for production of rigid filling waterproofing polyurethane, water- and acid-resistant, which is applied in damp-proofing of outer surfaces of constructions, for creation of protective force covering on polyurethane foam surfaces, for heat insulation of floors in refrigeration chambers, etc.

Characteristics of Components

à) “Korundinol 1010” (Component “A”)




Liquid coloured from yellow to light-brown without visible contaminating impurities

Hydroxyl number, mg KOH/g, in the range

320 - 420

Mass part of water, %, max.



b) Korundinat PM (Component “B”)

According to TU 2472-002-72311668-2004.

Processing Technique

Ratio of mixture À : B = 100 : 100 (by weight).

The compound is applied to the surface by pouring (after mechanical hand mixing in a reservoir) or by evaporation technique using high- or low-pressure machines at ambient temperature 18 - 25îÑ on a dry degreased surface.
