<p>Chemical activation of a surface of a base material of a polymer comprising a ketone function, comprises applying a gel formulation on the surface of material. The gel formulation comprises a reactive agent having ketone functions. Independent claims are included for: (1) the gel formulation comprising a low volatility organic solvent, a reducing agent consisting of metal hydrides, and a viscosity agent and/or a pro-viscosity agent consisting of low volatile ester, where the pro-viscosity agent is capable of reacting with reducing agent for forming partially-solvated solid species having a viscosifying effect; (2) preparing the gel formation comprising heating a mixture comprising the low volatile organic solvent, the reducing agent consisting of metal hydride, the viscosity agent and/or pro-viscosity agent, and cooling the obtained mixture; and (3) bonding two materials of which one is based on a polymer comprising ketone function, comprising activating the surface to be bonded to the material based on polymer, applying an adhesive layer on two surfaces to be bonded, and contacting the surfaces to be bonded.</p> |
