Adhesive bonding is one of the main methods used to join
1. a material and a coating such as inks and paints for the most common
2. parts processed in two steps, for example injected tail lights in two or three colours
3. several parts to produce a single device, for example bodies of trucks or buses
Bonding can be achieved:
4. Directly during processing, the most economical method
5. After processing by an indirect route by gluing, the most versatile way.
The involved materials are very diversified as we can see on the following figure 'Involved- Materials-in-Adhesive-Joining' possibly including paper, metal, glass, natural or synthetic textiles, wood, cements etc.
The main goals of adhesive bonding are generally:
1. To save costs by using standard parts joined by a simple process
2. To avoid mechanical damaging by drilling
3. To avoid thermal damaging by welding
4. To realise structural bonding
5. To add the properties of several materials in a single one such as multilayer films.
6. To reinforce polymers with textile.
