Product Features

When combined with a suitable Araldite® resin, such as GY 6010, PY 313, or GY 9513, the system offers:

  • A relatively high degree of flexibility
  • Good adhesion to dry concrete and sand-blasted steel
  • Suitable for formulating solvent free, benzyl alcohol free, and nonyl phenol free binder systems
  • The low viscosity makes it easy to handle
  • Formulated polyetherpolyamine giving high level of flexibility. Elongation 110% at 23°C and up to 50% down to -10°C.
  • Enables VOC free formulations
  • High elongation at break
  • Safer formulations with SVHC Free hardeners

Application Information

Flexible flooring and coating systems

  • Crack-covering membranes
  • To improve elongation and flexibility of brittle systems
  • Flexible adhesive systems
  • Solvent-free, benzyl alcohol free, and nonyl phenol free binder systems
  • Nonylphenol-free. Highly flexible, even down to -10 °C. Distinctly lower viscosity than ARADUR® 75 hardener and even than ARADUR® 76 hardener. For the production of nonylphenol-free viscoplastic binder systems, impact-elastic coatings, crack-covering membranes and liquid foils for sealing purposes.
