Aziridine cross-linker is a solvent-free、Aziridine cross-linking agent with solid content greater than 99%，Widely used in leather、textile、ink、coating、pressure sensitive adhesive、Adhesive、Curing agents and other fields，Washing resistance of its cross-linked film-forming products、wipe、Chemicals、and adhesion on the substrate are significantly improved.；
This cross-linking agent is an environmentally friendly cross-linking agent，No harmful substances such as formaldehyde are released after cross-linking，And the finished product is non-toxic after cross-linking、Tasteless；
The amount of increase is generally 1-3% of the solid content of the emulsion，It is better to add a lotion with a pH value of 8-9，Do not store in acidic media (PH<7) used in；
The aziridine cross-linking agent mainly reacts with the carboxyl groups in the emulsion.，It can also be combined with amine groups under strong acid catalysis、Hydroxyl produces cross-linking reaction，Therefore, aprotic organic bases should be used as much as possible when adjusting the pH value of the system.；
The aziridine cross-linking agent can produce cross-linking reactions at room temperature，But the baking effect is better at 60-80 degrees；
This cross-linking agent is a two-component cross-linking agent，Once you join the system, you should use it within two days.，Otherwise, partial gelation will form；
The cross-linking agent is miscible with water and common solvents，therefore，Generally, it can be mixed directly into the system under vigorous stirring.，It can also be dissolved in water and solvent first and then added to the system.；
The cross-linking agent is at room temperature、Storage period 24 months under sealed conditions；non-flammable、Explosives，But it is corrosive to a certain extent，Classified as dangerous goods。
