PPA - 7562 PHENALKAMINE EPOXY HARDENER
Download (Size : 526 KB)

Phenalkamine PPA - 7562 is Mannich base. It is an epoxy adduct of Phenalkamine in a solution form. Phenalkamine systems based on distilled CNSL show intense yellowing during exterior exposure. They also, have colour value very high on Gardner scale. PPA - 7562 is Phenalkamine developed to improve yellowing factor, as well as to assist formulator to develop light shades, in epoxy Phenalkamine systems.
