Polyamide Resin

Polyamide produce from the reaction of dimerised and trimerised fatty acid with polyamines. Polyamides are versatile curing agents for epoxies. They are pleasant to handle, are compatible with many resins, and their mixing ratio with resin are not critical. Fairly long pot life is possible. It yields casting with good impact strength. Excellent adhesion to many different substrates. Sometime polyamides are regarded as flexibilizers as well as curing agent. Polyamide Adducts provide good compatibility and better cure under adverse conditions than standard polyamides without induction time.

General Performance

  • Good flexibility & toughness
  • Long working life before gelation
  • Good water & Corrosion resistance
  • Low toxicity
  • Wide range of compatibility with epoxies
  • Low shrinkage on cure and exceptional dimensional stability
  • Excellent resistance to mechanical impact or shock
  • High flexural, compressive and tensile strength
  • Exceptional resistance to thermal shock
  • Good electrical resistance
  • Excellent adhesion and bonding to a wide variety of materials
  • Good machineability
  • Possibility for a wide range of properties – from hard and strong, to soft and resilient on the other.
