Applications:

Epoxy Systems:

D2000 acts as a curing agent in epoxy systems, contributing to increased toughness and impact resistance in the cured formulation. It's also used as a co-reactant in epoxy systems where increased flexibility and toughness are desired

Polyurea and Polyurethane:
D2000 is a key ingredient in polyurea and RIM (Reaction Injection Molding) formulations. Its fast reaction rate with isocyanates makes it suitable for these applications

Adhesives, Coatings, and Composites:
D2000's properties, such as increased peel strength and toughness, make it valuable in adhesives and coatings. It's also used in composite materials
