TERAMINE^® 654 is a versatile co-hardener and accelerator that is designed to enhance performance and formulation control in ambient-cure epoxy systems. It is a catalyzing additive engineered to facilitate reactions between epoxy resins and a wide range of hardener chemistries, delivering faster cure times and improved structural properties across demanding applications.

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, the product 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,” said Brian Taubler, vice president, global sales and business development, at Pflaumer. “It delivers consistent, dependable curing performance and greater processing latitude for epoxy systems that need to perform across a wide range of conditions.”

It is a highly efficient epoxy cure accelerator that offers precise control over cure speed. It activates reactions in cold or challenging environments and provides homopolymerization catalysis capability. The product is compliant with FDA Regulation 21 CFR 175.300 for use in direct food-contact articles.

Pflaumer recommends validating TERAMIN® 654 in the intended end-use environment prior to application. The product is intended for industrial use only.
