Fine-tune cure speed while preserving formulation flexibility
When used with conventional hardeners such as polyamides, polyamidoamines, aliphatic amines, and cycloaliphatic amines, TERAMINE® 654 functions as a highly effective catalyst, accelerating cure across a broad range of epoxy applications, including adhesives, electrical casting, impregnation, and high-performance composites. It is particularly valuable in applications that require precise, predictable cure behavior, even when fluctuating temperatures could otherwise compromise the coating’s properties during application.
Beyond its role as a co-hardener, TERAMINE® 654 can also be used in homopolymerization of epoxy resins, expanding its utility in composite and specialty epoxy formulations where enhanced structural performance is critical.
“TERAMINE® 654 gives formulators the ability to fine-tune cure speed while preserving formulation flexibility. It delivers consistent, dependable curing performance and greater processing latitude for epoxy systems that need to perform across a wide range of conditions,” commented Brian Taubler, vice president, Global Sales and Business Development at Pflaumer.
Key features of TERAMINE® 654
- Highly efficient epoxy cure accelerator
