Adhesives play increasing role for car makers

Increasing quantities of adhesives are used in the manufacture of motor vehicles up to 15kg per car.
How much would you trust an adhesive? Most of us will probably answer "not much".
Yet we are probably unaware of the major role that adhesives already play in the cars we drive.
Increasing quantities of adhesives are used in the manufacture of motor vehicles up to 15kg per car.
The growing requirements concerning stability, reliability and processing drive the adhesive manufacturers to continuously develop more efficient high tech products.
Approximately 0.02g of adhesive are necessary to seal a microswitch, and 0.1g for sealing airbag sensors.
These are minute amounts, which have to provide maximum performance to ensure the safety of the electronic vehicle control: permanent temperatures of up to 150C in the engine compartment, contact with chemicals such as motor oils, fuel, coolants and brake fluid.
High vibrations and extreme changes in condition must not influence the properties of the adhesive.
On top of that various materials have to be permanently joined.
This is a true challenge for any adhesive engineer and approximately 25% of R and D time at Delo is dedicated to developing automotive adhesives.
New automotive concepts and ideas are usually developed in the heads of design engineers, but the most forward thinking and successful ones are developed in continuous dialogue with area specialists.
Delo's most innovative adhesives originate from working together as partners with automobile manufacturers and electronic component suppliers, creating specific adhesives for these applications.
For instance, while a new electronic housing for an under-bonnet application is under development, it is worth co-ordinating the following areas at the earliest possible stage of development: selection of materials used, design of components, review of quality requirements, integration into existing production process.
It is during such discussions that developments evolve into some of the very clever design ideas that we use today and some even cleverer ideas we will be using tomorrow.
