DMTDA (equivalent to Ethacure 300) is a high-performance liquid polyurethane curative and crosslinking agent. It is typically in a ratio of 77–80/17–20. In contrast to the industry‑standard MOCA, DMTDA remains a low‑viscosity liquid at room temperature, making it ideal for low‑temperature processing and construction applications.
