Tenax Polyester Hardener Only - 180ML Tube

This is the Tenax Polyester Hardener for Tenax Polyester resins. The Polyester resin you purchase does come with hardener, but since the mix ratio is 3% hardener to resin some of our cusomers request extra hardener, because mixing that type of ratio is an inexact science. This 180-ml tube will harden 4 - 5 liters of polyester resin. This is only the Tenax Polyester Hardener - Polyester resin is NOT included! This is a HazMat (hazardous material).
