What is ISO 21194 – Elastic adhesives about?
ISO 21194 specifies a method for evaluating the adhesion of elastic adhesives and sealants (with a minimum elongation at break of 100 % and a modulus of elasticity of maximum 10 MPa1) on various substrates. In this way, the effect of various coatings or the surface pre-treatments of the substrate materials on the adhesion can be compared.
ISO 21194 can also be used to evaluate the influence of pre-treatment substrate and adhesive on the long-term durability of adhesively bonded joints and seals. This test can also be used for process monitoring and quality assurance accompanying production.
Who is ISO 21194 – Elastic adhesives for?
ISO 21194 on adhesives is relevant to:
- Manufacturers of elastic adhesives
- Chemical Engineer
- Any entity responsible for testing and quality of adhesives
Why should you use ISO 21194 – Elastic adhesives?
The elastic adhesives form a tough, flexible rubber-like elastic body after curing. As a highly functional universal adhesive that is resistant to vibration and impact and has excellent stress relaxation characteristics, they can be used with confidence in a wide range of applications.
ISO 21194 provides methods to test the strength of adhesively bonded joints using bead peel test method in elastic adhesives and covers all significant requirements, methods used to test bonded joints.
Overall, ISO 21194 is a comprehensive guide to provide methods for testing adhesively bonded joints, so users will gain deeper understanding of the quality of adhesives to improve the durability and strength of the devices.
