Adipic Acid Dihydrazide – A Unique Crosslinking Agent and Curative

Adipic acid dihydrazide (ADH) is an effective crosslinking agent, curative and hardener.  It is the most common dihydrazide crosslinking agent within a series of dihydrazides such as sebacic dihydrazide (SDH) and isophthalic dihydrazide (IDH).  ADH’s has a melting point of 180 °C and a molecular weight of 174; both are lower than the alternative dihydrazides SDH and IDH.

Water-Based Acrylic Resins & Binders

Water-based acrylic binders meet environmental requirements for the absence of VOCs, in addition to low toxicity and odor.  The diversity of acrylic systems available can be designed to meet binder applications across the spectrum of substrates and printing technologies.  Binders should form films smoothly and easily at ambient temperatures.  Binders can be readily designed that have a range of Tgs and surface hardness, from low Tgs for flexible surfaces to high Tgs for rigid substrates.  The diversity of acrylic monomers and vinyl monomers allow this to be accomplished while meeting other requirements for fast-drying properties, adhesion, water and abrasion resistance, and gloss.  The addition of low levels of isopropanol in ink formulations reduces the surface energy of the system, improving ink leveling, thickness, and density control on plastics.

PET Crystallinity Modification

Polyethylene Terephthalate (PET) is produced from esterification of mono ethylene glycol (MEG) with terephthalic acid (TPA), or from transesterification of mono ethylene glycol (MEG) with dimethyl terephthalate (DMT). But, what would happen if you substituted 2-methyl-1,3-propanediol (MPO) for mono ethylene glycol (MEG) in the PET polymerization process?
