Araldite® CW 2243-2 L and Aradur® HY 842 based on the provided technical data sheet:


1. Product Overview

Araldite® CW 2243-2 L is a modified, solvent-free epoxy resin containing inorganic fillers, while Aradur® HY 842 is a low-viscosity polyamidoamine hardener. This optimally filled casting system is designed for processing and curing at slightly elevated temperatures, offering low viscosity, flexible castings, and good thermal shock resistance.

2. Applications

  • Small transformers
  • Suppressor chokes
  • Suitable for casting and vacuum casting
