Used primarily as a curing agent or hardening accelerator in epoxy resin systems, especially in industrial coatings and adhesives. Its reactivity with epoxy groups ensures rapid crosslinking, resulting in strong, durable, and chemically resistant bonds. Commonly applied in marine coatings, pipeline protection, and electrical encapsulation due to its ability to form stable, moisture-resistant networks. Also utilized in specialty chemical synthesis where a protected diamine is required, allowing controlled release of the amine functionality under specific conditions.
