XC-103 trifunctional aziridine is utilized as a crosslinking agent and adhesion promoter; When used as a cross-linker, XC-103 dramatically improves the final properties of adhesives, coatings and printing inks. It imparts strength and flexibility, improves solvent, alcohol and water resistance, and improves adhesion to difficult substrates;
XC-103 high molecular tri-functional aziridine reacts with carboxyl groups of acrylic emulsions and polyurethane dispersions forming cross-link network;
XC-103 is added to finish formulated coating systems just prior to use. It is added slowly with agitation, directly to the formulated coating systems. It can be added neat or in solution. If added in solution, a solvent without active hydrogen should be used.
Dosage: The addition level of XC-103 is 1% to 3% based on resin solid in most applications. Higher level, such as 5%, may yield higher solvent resistance and adhesion properties;
PH: An aqueous system with pH of 9.0-9.5, at the time addition, produces most often the optimum results. A lower pH may cause the aziridine to react prematurely in the pot |
