Beschreibung
Adipic dihydrazide (ADH) is the most suitable hydrazide cross-linking agent, and ADH has been widely used in water-based paint emulsions in combination with diacetone acrylamide. ADH is weakly alkaline, and there is a possibility of agglomeration when solid ADH is added directly to the emulsion, so usually ADH should be dissolved in hot water before use.
Chemische Eigenschaften
white to slightly yellow crystalline powder
Verwenden
Adipic dihydrazide is used as a formaldehyde scavenger and reacts with formaldehyde, thereby preventing the volatilizing of formaldehyde in the air. It is also employed as a paint additive and coating additive. It is also used as an intermediate. Further, it is used for cross-linking water-based emulsions and as a hardener for certain epoxy resins, which finds application in powder coating.
Verwenden
Adipic acid dihydrazide is a homobifunctional cross-linking reagent specific for aldehydes resulting in relatively stable hydrazone linkages. Adipic acid dihydrazide is typically, used in the linking of glycoproteins, such as antibodies, in a site specific fashion following periodate oxidation. Oxidation and coupling may conveniently be performed at pH 5.0 due to the low pKa of the hydrazide which avoids competition by primary amines.
Flammability and Explosibility
Non flammable
