Two-component PU system based on Korundinol 1010 (Component
“A”) and “Korundinat
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.

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.
