ARA® XTREME

ARA® XTREME PY 2100 US is a very low-viscosity, high-functionality amine-based, high-purity resin with relatively good storage stability. It cures very rapidly to produce products with exceptionally high heat deflection temperatures. ARA® XTREME PY 2100 US is particularly effective in a wide variety of formulating applications, including adhesives, laminating systems, and more. It can be used as a viscosity modifier and, in combination with slow-reactivity resins, can boost their cure rate. However, caution must be exercised in the selection of hardeners and cure conditions due to its rapid curing characteristics. Even moderate amounts, when cured with aliphatic amines, can develop sufficient exotherm to cause charring and smoke evolution. This can also occur if aromatic amine-hardened systems are gelled at excessively high temperatures or if catalysts, such as boron trifluoride monoethylamine, are used alone or in conjunction with aromatic hardeners.

ARA® XTREME PY 2300 is a single-ingredient material from the epoxy and epoxy derivatives family, designed for high-performance applications requiring robust structural properties.
