EH-101: Fast Epoxy Hardener


 

 
   

Product Description

EH-101 is an aliphatic epoxy hardener that is compatible with both ‘DR’ and ‘ER’ series resin systems.  Hardener has no free-phenols

and has excellent room temperature properties.

Processing

Mix resin and hardener thoroughly at specified ratio.  Resin can be heated slightly to lower viscosity.  Do not expose resin or hardener

to excessive moisture conditions until fully cured.  Post-cure resin to 160oF to achieve maximum cure and composite strength.  In cases

of free standing post-cures, the part should be heated slowly

(20-30oF per 30 minute steps) to prevent warpage.

Applications

• Small hand laminated parts requiring less than 1

   hour working time

• Fairing, bonding and joining composite parts

* Very compatible with two phase ‘DR’ series resins for added adhesion.
