Excellent for bonding reinforcement materials such as Glass or Carbon onto wood.

Suitable for room temperature applications, gives a high gloss finish, a low surface pollution and is UV stable.

  • This epoxy system has a low toxicity.
  • Production of composite structures by wet lay-up method
  • Infusion, vacuum and low pressure injection.
  • Good behaviour on wood impregnation and bonding.
  • Good mechanical properties
  • Low viscosity
  • Fast and slow hardeners
