The solid adhesives optimized in this project present the following technical characteristics:
Products of a thermoplastic nature presented in film form
They are only applied to one of the surfaces to be joined
They are heat activated at temperatures that are easily within reach of conventional reactivation methods
The two surfaces are joined and pressed.

The joins produced with these products fulfil all the requirements needed for quality bonding in footwear and leather-goods, furthermore, they do not present any problems of compatibility with the materials usually used for manufacture.

Finally, different procedures have been established for the application of these adhesives which have served as a base for the small scale preparation of prototypes, which will have to be industrially validated and adapted to different production processes.
