Technical collage 4 : conclusion

The important progress made in the field of the adhesives (generic term of the adhesives, cements and coating) allows the assembly of the near total of materials. The technical and economic consequences make that they are used more and more in sectors as various as mechanics, the textile, wood, transport, the building.

It is in the assembly that the evolution is most spectacular because sometimes, if joining replaces the means traditionally employed, it has the advantage of widening in an important way the framework of the applications. So it is often preferred for one or more of the following reasons:

Uniform distribution of the efforts on the whole of film of adhesive

Price with the m ² often less low Invisible means of assembly (decoration)

Sealing and protection counter corrosion carried out at the same time as the Suppression assembly of the resumption of parts (fettling, sandpapering, cementing.)

Very different material assembly

But all these qualities should not make forget that joining is technique of a modern and rather complex assembly to implement. It is necessary to have good knowledge in the theory of the adhesive to be able to apply this method under satisfactory conditions.

Collage should not be a palliative or a spare wheel. It is necessary to think of joining as of the design of the product. The conditions of success are all the more large as one controls the theory of the adhesives and that one has good notions of the adhesives available on the market.
