PZH-25

SPECIFICATIONS

PZH-25 is a propylene imine bi-functional aliphatic polyaziridine dissolved in dipropylene glycol methyl ether, that is used as a crosslinker 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.

The product is easy to mix with aqueous bases targeted to heat curing 2K processes. 80ºC are usually enough to start the crosslinking reaction.
