1 ADH is a crosslinker of waterborne acryl emulsions.
2 It is also useful as an epoxy resin hardener and a formaldehyde scavenger.
3 ADH reacts very rapidly with ketone groups. For example, it reacts easily with ketone groups of diacetone acrylamide or aldehyde groups of formaldehyde.
4 ADH also reacts with the epoxy group like an amino compound.
---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.
---Epoxy resin hardener ADH reacts with epoxy resin at high temperature and is useful for powder coating.
---Reforming of plastic Fiber processing;
Thanks to environmental regulations limiting volatile organic compounds (VOCs) and major improvements in the performance characteristics of the emulsion-based products, aqueous acrylic polymer emulsions are replacing solvent-based polymer systems.
