Alias: Malonic Dihydrazide Used as latent hardener for epoxy resin powder coating, reference dosage is 7-8 parts, probation period is more than 3 months.Curing conditions 150℃/20-30min. Lower curing temperature than dicyandiamide, curing time end, good water resistance, high bonding strength, 150℃/30min. The shear strength of curing is 24.4MPa.The thermal deformation temperature of the cured material is 160-165℃.It is also used as a quick curing crosslinking agent for modified polyvinyl acetate emulsion to improve the initial and final bonding strength and water resistance.
