Proposed use
1. Suitable for acrylic resin containing carboxyl, polyurethane resin, etc.;
2. Widely used in water-based ink, paint, heterocyclic block, pharmaceutical raw materials and intermediates.
Method of application
It can be added directly or after dilution with a solvent or water which does not contain active hydrogen. The addition amount depend on that performance requirements of the coat and is generally 1- 3 % of the resin solid content, and 5 % can be added. And a coating with higher solvent resistance is formed after curing. The pH value had a greater effect on the crosslinking rate. When the pH value of the emulsion was controlled within 9.0–9.5, the optimum effect could be obtained by adding multi-aziridine crosslinker. Aziridine compounds are sensitive to active hydrogen groups and cannot be contacted with acidic substances and strong oxidizing agents.
