Epoxy Resin Hardeners (HN-2200, MHAC-P)
About the product
These alicyclic acid anhydride type have less toxicity, longer pot life and lower exothermic characteristics in comparison with amine type hardeners. Applications of these epoxy resin hardeners extend over to casting, impregnation, lamination and many others.
Features
- These liquid hardeners are easy to mix with epoxy resin.
- These hardeners have less toxicity than amine hardeners.
- The epoxy compounds mixed with these liquid hardeners have longer pot life.
- MHAC contributes excellent heat resistance to the cured epoxy resin compounds.
