K-PURE CDR-3320 is a unique oligomeric ester that has an affinity for metal surfaces. As a result, CDR-3320 creates a barrier layer at metal surfaces that passivates the potential for corrosion caused by corrosive ions. Due to its unique chemistry, CDR-3320 may also react with amino based systems. This reactivity plus the affinity for metal surfaces will also promote adhesion of organic coatings to metal substrates.



ADVANTAGES:
Effective for various metals; copper, iron, steel, brass, aluminum.
May reduced induction (or setting) time in 2K Epoxy Formulations
Wet adhesion promotion
