Adipic acid dihydrazide [ADH]
ADH is a crosslinker of waterborne acryl emulsions. It is also useful as an epoxy resin hardener and a formaldehyde scavenger.

Features
ADH reacts very rapidly with ketone groups.
For example, it reacts easily with ketone groups of diacetone acrylamide or aldehyde groups of formaldehyde.
In addition, ADH also reacts with the epoxy group like an amino compound.
Applications
Room temperature crosslinkable waterborne coatings
Acryl emulsion comprising acryl monomers and diacetone acrylamide crosslinks with amino groups of ADH very rapidly.
The coating has excellent water resistance.
Formaldehyde scavenger
ADH reacts with formaldehyde and prevents volatilizing of formaldehyde in the air.
Epoxy resin hardener
ADH reacts with epoxy resin at high temperature and is useful for powder coating.
