Dicyanex 325 Air Products Crosslinking / Coupling / Curing Agents >> Amines /Amides >> dicyandiamide Epoxy (EP) Dicyanex 325 is a pulverized grade of dicyandiamide containing 3% of an inert flow control additive to inhibit clumping and improve handling. It is designed for use as a latent curing agent for epoxy resins. Enhanced solubility in polar solvents, such as acetone and DMF, due to reduced particle size High level of inert flow control additive prevents clumping and facilitates dispersion into liquid resins Enhanced reactivity versus nonpulverized grades in solvent-free systems Shelf stability of up to 6 months @ 77 °F (25 °C) in properly formulated systems Activation temperature can be varied easily from 356 °F - 203 °F (180 °C - 95 °C) with appropriate accelerator selection Application: One-component adhesives Dicyandiamide latent curing agent used for epoxy resins in one-component adhesives. Pulverized grade. Enhanced solubility in polar solvents (acetone, DMF). Provides clumping and dispersion into liquid resins, enhanced reactivity versus nonpulverized grades in solvent-free systems, shelf stability of up to 6 months at 25 °C in properly formulated systems.Activation temperature can be varied easily from 180 °C - 95 °C with appropriate accelerator selection. Typical cure schedule: 1-2 hr at 180 °C; 45 min at 120 °C with 0.5 parts of curing agent. Recommended Use Level (phr, EEW=190): 4-15.
