- Product Highlights
Trazidin VN polyfunctional aziridine is utilized as a cross-linking agent and adhesion promoter and modifier. TRAZIDIN VN aziridine contains three aziridine groups in a high molecular weight, low volatile, molecule. Each aziridine group can react with an active H+, as found in the carboxyl groups of acrylic emulsions and polyurethane dispersions. This reaction protonates and opens the aziridine ring, which then reacts with the oxygen of the carboxyl groups forming a cross-link network.
Applications & Uses
- Applications
When used as a cross-linker, Trazidin VN aziridine dramatically improves the final properties of many adhesive, coating, and printing applications. It imparts strength and flexibility, improves solvent resistance, alcohol and water resistance, increases hardness, and upgrades adhesion to difficult substrates.
