Tenax Polyester Hardener

Tenax Polyester Hardener is 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 inexat 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! Stock up on the Tenax Polyester Hardener so you don't run out.

This is a HazMat (hazardous material). There will be additional HazMat fees if this is for delivery outside of the continental USA or if you request the order to be shipped by other means than UPS ground delivery. If any additional fees apply to this order you will be contacted prior to us shipping the order for your approval.
