ARADUR® 956-2 Hardener is a versatile hardener that can be used for many applications, particularly adhesives, castings, encapsulation and potting compounds where its low viscosity and low shrinkage are advantageous. It is based on triethylene tetramine (TETA) and is chemically modified to facilitate the formulation of systems made with ARALDITE® liquid epoxy resins, fillers and other modifiers for curing at ambient or elevated temperature.
