Phenalkamine Epoxy Hardeners

Ark Golden has gained an expertise in the production of Phenalkamine Hardeners. The distinctive qualities of these hardeners have complemented the technical abilities of the company and its management in achieving rapid growth in the industry. Phenalkamine Hardeners are unique hardeners with inherent property to cure epoxy resins at low temperatures down to 0°C under high humidity with surface tolerance and adequate flexibility. As a result, Phenalkamine Hardeners have an edge over both polyamides and polyamines in the field of mainly Marine & Protective Epoxy Coatings.

• Reactivity Pattern: Ark 147 > Ark 146 > AG 140 > AG 1400 > Ark 351 > AG 141 > AG 1411
• Chemical Resistance: Ark 147 > Ark 146 > AG 140 > AG 1400 > Ark 351 > AG 141 > AG 1411
• Flexibility: AG 1411 > AG 141 > Ark 351 > AG 1400 > AG 140 > Ark 146 > AG 147


• Ark 146 is comparatively flexible and improved pot life but slow than Ark 147
• Ark 147 is a new and rapid curing phenalkamine with better chemical resistance
• AG 1400 is ideal for coal tar based epoxy system
