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. DAAM is widely used as cross-linker in waterborne acrylic emulsions.

The Superiority of the Diacetone Acrylamide (DAAM) and Adipic Acid Dihydrazide(ADH) Crosslinking System

---DAAM and ADH are easy and safe to use.
---Both intermediates are formaldehyde free.
---DAAM uniformly copolymerizes within acrylic copolymers, creating well-dispersed pendant ketone crosslinking sites.
---Wet acrylic emulsions based on DAAM with ADH in the aqueous phase, are initially non-reactive and afford emulsions with good long-term stability during shipping and storage in retail containers (i.e., “in-can” stability).
---After film coalescence, crosslinking becomes rapid at ambient temperatures, thanks to water evaporation in the drying process and a simultaneous reduction in pH arising from the loss of ammonia.
---Because crosslinking is post-coalescence, the resulting three-dimensional polymer network exhibits enhanced mechanical strength and durability as well as maximum film cohesive properties.
---Crosslinking with the keto-hydrazide chemistry enhances abrasion, scrub, stain, and blocking resistance; moisture and solvent resistance; and substrate adhesion.
