What is BS EN 17408 about?
BS EN 17408 specifies a measuring method for the characterization of rheological properties of structural adhesives using oscillatory rheometry. Moreover, the testing procedure can be applied to the reactive mixture of several components or the components of a reactive bonding paste material.
The method described is particularly suitable for filled and paste-like adhesives. These are frequently processed using automated pump and application systems in industrial applications and will be set precisely considering their rheological properties. As the rheological behaviour of uncured adhesives is mostly independent of their properties in the cured state, BS EN 17408 can also serve for the examination of non-structural adhesives.
Who is BS EN 17408 for?
BS EN 17408 on the determination of the flowability and application behaviour of viscoelastic adhesives using the oscillatory rheometry is useful for:
- Construction of buildings
- Automobile manufacturers
- Computer hardware manufacturers
- Helmets manufacturers
- Theatres and auditoriums
- Viscoelastic adhesives manufacturers
Why should you use BS EN 17408?
Viscoelastic adhesives are polymeric polymers that have viscoelastic properties. When a polymer is stressed, a portion of the energy is lost by chain movement. These viscous losses are temperature and time dependant.
BS EN 17408 will help you in displaying good flowability under pressure and ensure the stability of pasty adhesives. A short stringing is useful in the process as it prevents the contamination of the components. The oscillatory rheometer is useful in recording the linear-viscoelastic range, small deformations and low torques.
BS EN 17408 ensures good reproducibility by working in a uniform way, this is achieved by using sampling and sample preparation. This BS EN 17408 helps in measuring the gaps which result in filling these gaps in viscoelastic adhesives by using oscillatory rheometry.
BS EN 17408 is useful for you as it combines viscous and elastic properties by measuring the rotational viscometry. BS EN 17408 helps in determining the behavioural flow of material that results in a better understanding of their processing properties.
