PolyAziridine Global PZP-1000

PolyAziridine Global PZP-1000 is a propylene imine tri-functional polyaziridine that is used as a cross linker for both aqueous and non-aqueous coatings, inks, and adhesives to promote both physical and chemical properties. The aziridine end groups can react with active hydrogen as found on carboxyl groups of acrylic emulsions or polyurethane dispersions. PZP-1000 is added at levels of 1% to 3% to finished formulated coatings, inks, or adhesives. It is added slowly and under good agitation. After mixing, an aqueous system with a pH of 9.0-9.5 will typically have a pot life of 18-36 hours. This time will be reduced when the pH is lower.
