SR 5550 has been especially formulated for building marine composites: bonding, laminating and wood protection. It has an excellent adhesion to all type of wood. This system is handy with multiple hardeners available. It has a low viscosity and is crystallisation free.
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
