DETDA

Lica DETDA is a liquid-type aromatic curing agent and chain extender, predominantly employed in polyurea and polyurethane systems. It is optimally formulated for applications such as Reaction Injection Molding (RIM) and Spray Polyurea Elastomer (SPUA) processes. Lica DETDA ensures rapid curing and thorough surface drying of polyurethane and epoxy resin coatings, effectively sealing and protecting floors, external walls, roofs, and bridges. In terms of use in PU products, Lica DETDA demonstrates superior mechanical performance. Its low viscosity enhances ease of application.
