NORSOL X-LINKER
FOR USE WITH ALL NORSOL LEATHER TOPCOATS
Crosslinking polyisocyanate for aqueous leather finishes
Improves the wear resistance and adhesion of polyurethane topcoats
Application
Norsol X-Linker is added to the topcoat, immediately before use.
The amount required is between 5 and 20 %, depending on the desired fastness properties.
(10% as standard)
The crosslinking agent should not be diluted before addition.
Apply by spraygun or sponge.
We recommend using within 3 hours once mixed.
The pot life of topcoats activated with Norsol X-Linker is in line with the normal pot life of isocyanatecrosslinking agents. (3 -4 hours)
An increase in viscosity and precipitation indicate that the pot life has been exceeded and that the formulation can no longer be used.
Formulations which have been left to stand for a prolonged period are not necessarily suitable for use, even if the appearance and viscosity are unchanged.
The crosslinking reaction in the finish film is more or less complete after about 2 days.
Do Not use on Nubuck or Suede
