Properties Related to the Method of Use

In this section, we will study only the bonding properties of adhesives. For sealants, the methods of use are different because they are not supposed to give a strong assembly but instead to fill a gap and seal against humidity, water, etc., so that their technical characteristics are different. We will study their specific properties in the various chapters devoted to sealants in this Handbook, in Volumes 3, 5 and 6 (refer to list of contents). 

Every bonding process involves 8 or 9 different steps (Fig. 13)  

surface preparation cleaning of substrates, surface preparation by mechanical, physical or chemical techniques, 

preparation of the adhesive mixing the 2 components, diluting, melting the hot melts, 

application with various systems hand tools, rollers, spray gun, extrusion, etc.
