Modified silanes adhesives were developed and launched in Japan during the 80’s, due to the great advantage of these elastic adhesive compared to polyurethane adhesives, its use is highly increase both Europe and America markets.
Modified silanes are one component adhesives which react and cure under the action of moisture, during its curing process by polycondensation this type of adhesives emit methanol and once cured acquire elastic properties and typical strength of an elastomeric material.
Most widely used organosilanes have one organic substituent and three hydrolyzable substituents. In most surface treatment applications, the alkoxy groups of trialkoxysilane are hydrolyzed to form silanol-containing materials. The reaction of these silanes involves four steps. Initially, three unstable groups were hydrolyzed. Condensation to oligomers. Then, the oligomer is hydrogen bonded to the 0H group of the substrate. Finally, during drying or curing, a covalent bond is formed with the substrate while losing water. Although described in sequence, these reactions can occur simultaneously after the initial hydrolysis step. At the interface, there is usually only one bond from each silicon of the organosilane to the substrate surface.
