Abstract

Methods of applying and combining cleaning solvent with titanate adhesion promoter to a polymeric substrate are disclosed. In one embodiment, method of applying the solvent mixture includes providing a polymeric substrate to be treated. The polymeric substrate is treated with the reactivation solution comprising a cleaning agent and a titanate adhesion promoter. The reactivation solution is applied to the polymeric substrate and allowed to treat the polymeric substrate by simultaneously cleaning and promoting adhesion, reactivating the surface in preparation for adhesion between the substrate and another material. Finally, another material is applied to the treated polymeric substrate and the method is repeated, if desired. Embodiments of the invention provide the desired production and labor efficiency, while further addressing the risk to personnel in treating a variety of polymeric substrates.

Claims

1. A method of treating a polymeric substrate surface, comprising:

combining a cleaning agent with an adhesion promoter to form a reactivation solution, the adhesion promoter including a titanate compound; and

simultaneously cleaning and reactivating the polymeric substrate for adhesion to another material by applying the reactivation solution.

2. The method of claim 1, wherein cleaning and reactivating is performed concurrently by applying a chemical mixture comprising a cleaning agent and an adhesion promoter to the polymeric substrate.

3. The method of claim 1, wherein cleaning the polymeric substrate includes removing loose components and contaminants.

4. The method of claim 1, wherein the cleaning agent comprises a volatile organic compound solvent mixture, said mixture comprising at least one of Methyl Ethyl Ketone (MEK), Toluene, Isopropyl Alcohol (IPA), and Methyl Isobutyl Ketone (MIBK).

5. The method of claim 4, wherein the volatile organic compound solvent mixture includes MEK and Toluene in a greatest volume fraction.

6. The method of claim 4, wherein the cleaning agent comprises at least one of additional ingredients, solvents and surfactants to assist in solubility of the adhesion promoter, including Oxol.

7. A method of forming a reactivation solution, comprising:

combining a cleaning agent with an adhesion promoter, the adhesion promoter including a titanate compound; and

simultaneously cleaning and reactivating the polymeric substrate for adhesion to another material by applying the reactivation solution.
