EPOXY RESINS USES OF ADIPIC ACID DIHYDRAZIDE (ADH):
A notable fact with regard to Adipic Acid Dihydrazide (ADH) in epoxy formulations is that each of the primary amine end groups has a functionality of two, so the ADH molecule has an equivalency of four per epoxy moiety.
Accordingly, the active hydrogen equivalent weight of Adipic Acid Dihydrazide (ADH) is 43.5.

When formulated with epoxy resins, the Adipic Acid Dihydrazide (ADH) index can range between 0.85-1.15 of stoichiometric proportions, without a significant effect on mechanical properties.
The cure temperature for epoxy resins (glycidyl types) formulated with Adipic Acid Dihydrazide (ADH) is influenced by the melt-out temperature of the ADH, which allows an extended pot life at low temperatures.

Storage stability can be up to six-months at room temperature, with cure times of about one-hour at 130 °C.
Cure rates can be accelerated using tin or titanate catalysts, or imidazoles.
One-component Adipic Acid Dihydrazide (ADH) epoxy systems can be partially cured or “B-staged”, and later fully cured.

B-staging provides handling, processing, and fabrication advantages.
One component epoxy resins are used in coatings such as powder coatings, adhesives including hot melt adhesives, molding compounds and in fiber reinforced composites.

Glass and carbon fiber prepreg obtained by a hot melt impregnation method are used in the fabrication of sporting goods, wind turbine blades and aircraft/aerospace components.
With Adipic Acid Dihydrazide (ADH) cure, epoxy resins exhibit excellent toughness, flexibility, and adhesive properties.

Tg’s of 140-160 °C are achievable using a standard liquid bisphenol A epoxy resin (DGEBA) with Adipic Acid Dihydrazide (ADH) as the hardener.
Rigid and flexible epoxy adhesives have been formulated as one component systems that can be stored at room temperature using Adipic Acid Dihydrazide (ADH) as a latent curing agent.

Rigid epoxy adhesives are based on bisphenol A and novolac epoxides.
These rigid adhesives exhibit excellent cohesive and adhesive properties to a wide variety of surfaces.
Flexible epoxy adhesives produce more pliable bonds which better accommodate bond line stresses or differential substrate expansion rates.

Flexible epoxy resins include aliphatic di- and tri-epoxy resins such as hexanediol diglycidyl ether and poly(oxypropylene) diglycidyl ethers.
Semi-rigid epoxy-based adhesives utilize mixtures of both classes of epoxy resins or rigid formulations using flexibilizers.

POLYURETHANE DISPERSIONS (PUDs) USES OF ADIPIC ACID DIHYDRAZIDE (ADH):
Adipic Acid Dihydrazide (ADH) is an effective room temperature curative for aqueous PUDs and solution polyurethanes.
In this capacity, Adipic Acid Dihydrazide (ADH) provides polyurea coatings with higher hardness, toughness and adhesion properties, excellent mechanical properties, abrasion and chemical resistance.

Adipic Acid Dihydrazide (ADH) cured polyurethane coatings exhibit good color stability and weathering properties, which is not observed with standard amine curatives.
ADH is added to the water phase in a PUD.

Crosslinking occurs during the drying and film coalescence process which is ideal for maximizing the film properties including gloss, scrub, stain and wear resistance and durability.
Other crosslinking methods where crosslinking occurs prior to film coalescence exhibit reduced performance properties including poor flow and leveling.

The full reactivity characteristics of ADH are ideal for PUR systems.
Alternative curatives which show incomplete crosslinking due to slow reactivity and the lack of curative mobility in a dry film will also compromise performance.

ACRYLIC RESINS USES OF ADIPIC ACID DIHYDRAZIDE (ADH):
A large swath of our portfolio of customers at Gantrade produces acrylic resins to create high-performance products across a variety of industries worldwide.

The leading crosslinking technology for acrylic emulsion polymers is ambient temperature crosslinking chemistry based on diacetone acrylamide (DAAM) or acetoacetoxyethyl methacrylate (AAEM) and Adipic Acid Dihydrazide (ADH) monomers.

This technology, known as “keto-hydrazide crosslinking,” involves the direct reaction of the pendant ketone moiety on the DAAM-acrylic or AAEM acrylic polymer segment and the hydrazide moiety of the Adipic Acid Dihydrazide (ADH), with the evaporation of water in the film-forming process.

This self-crosslinking technology has been adopted in high-durability paints and coatings for architecture, wood, and concrete surfaces, and more.
