Dicyandiamide (DICY)

Specifications

Detail Introduction

Product Name: Dicyandiamide (C₂H₄N₄)

Dicyandiamide, commonly known as dicyandiamide, is a latent curing agent that has been used for a long time, and is widely used in coatings, single-pack adhesives, film adhesives, etc. Dicyandiamide is a white crystal with a melting point of 207~209°C, low toxicity, but insoluble in epoxy resin. According to data reports, dicyandiamide can be dissolved in epoxy resin by solvent, but at present, dicyandiamide is pulverized and mixed with epoxy resin, heated and kneaded on triple rollers, or processed by extruder. Usually the mixture without accelerator is suitable for more than half a year.

The curing mechanism of dicyandiamide is relatively complicated. In addition to four active hydrogens participating in the reaction, the cyano group is also reactive. In addition, dicyandiamide also acts as a catalytic curing agent. For E-51 epoxy resin, the theoretical dosage of dicyandiamide is 11g per 100g resin, while the actual dosage is 4~10g, especially for solid epoxy resin, the general dosage is relatively small.
