Polyaziridine crosslinker KL-1500/E CAS 7417-99-4

As resin insolubilizer and fixing aid in printing process carried out at low temperature, in order to

improve durability to abrasion and washing of the designs in the treated textiles. Unlike primary

condensates of melamine or urea resins, it does not generate formaldehyde during heat treatment.

Also it does not generate CO2, as would do standard isocyanates.

It can be used with various functional groups like carboxyl moieties, hydroxyl, chlorosulfonic, amines

and even esters under appropriate conditions. These conditions range from room temperature for the

carboxylic groups to 150degree for the hydroxyl pending groups. Most standard conditions range from

80 to 120 degree in order to speed and complete cross linking process. Normal dosing varies depending

on application process and results, but 1% to 3% of the dispersion over total formulation may be a good starting point.
