Process for removal of paint from plastic substrates

1. A method of removing paint from a plastic substrate at east partially coated with a paint coating comprising the steps of:

providing at least one plastic substrate at least partially coated with a paint coating;

providing a kit for a user to utilize to remove paint from the plastic substrate, which is at least partially coated with a paint coating, wherein the kit comprises:

a first mix of components comprising: at least one aromatic alcohol; an alpha-hydroxy acid; an anionic surfactant; 2-mercaptobenzothiazole or salts thereof; and a xylene; and

instructions instructing an end user to remove paint from the plastic substrate using the first mix of components; wherein the first mix of components is packaged together with the instructions within the kit;

immersing the at least partially coated plastic substrate into a first immersion bath comprising the first mix of components and water; and

rinsing the plastic substrate with water; and

wherein the immersing and rinsing steps remove at least a portion of the paint coating from the plastic substrate.

2. The method of claim 1 , wherein the components of the first mix are concentrated and the process further comprises the step of adding water to the concentrated first mix to form the first immersion bath prior to immersing the at least partially coated plastic substrate into the first immersion bath.

3. The method of claim 1 , wherein the at least one aromatic alcohol comprises benzyl alcohol and the at least one aromatic alcohol comprises from about 50% to about 55% by weight; wherein the anionic surfactant comprises sodium lauryl sulphate and the anionic surfactant comprises from about 0.5% to 1.5% by weight; wherein 2-mercaptobenzothiazole or salts thereof comprises from about 0.5% to about 1% by weight; wherein the water comprises from about 30% to about 40% by weight; wherein the xylene comprises from about 0.1% to about 1% by weight; and wherein the alpha-hydroxy acid comprises glycolic acid and the alpha-hydroxy acid comprises from about 5% to about 10% by weight; and wherein the first immersion bath is at a temperature of about 140° F. to about 180° F.

4. The process of claim 1 further comprising the step of reducing the size of the plastic substrate to form a plurality of plastic substrates.

5. The process of claim 1 further comprising the steps of immersing the at least partially coated plastic substrate into a second immersion bath comprising a second mix after immersing the at least partially coated plastic substrate in the first immersion bath wherein the second mix comprises dipropylene glycol, dimethyl ether, dimethyl succinate, dimethyl glutarate, and dimethyl adipate.

6. The method of claim 1 , wherein the kit further comprises a second mix of components and the method further comprises the steps of immersing the at least partially coated plastic substrate in the second mix of components and rinsing the at least partially coated plastic substrate after immersing the at least partially coated plastic substrate in the second mix of components.

7. The method of claim 2 , wherein the plastic substrate comprises a plastic substrate selected from the group consisting of: nylon, polypropylene, polyphenylene oxide (PPO), polyethylene, polycarbonate, thermoplastic polyolefins, polyamide (PA), polyphenylene ether (PPE), thermoplastic urethanes, blended nylon, polyvinyl chloride, polystyrenes, and mixtures thereof.

8. The process of claim 3 further comprising the steps of collecting the plastic substrate and forming a new plastic substrate using the collected plastic substrate.

9. The process of claim 4 , wherein the step of reducing the size of the plastic substrate to form a plurality of plastic substrates is before the step of immersing the at least partially coated substrate into the first immersion bath.

10. The method of claim 6 , wherein the second mix of components comprises: dipropylene glycol, dimethyl ether, dimethyl succinate, dimethyl glutarate, and dimethyl adipate.

11. The method of claim 6 , wherein the second mix of components is a second concentrated mix of components.

12. The method of claim 11 , wherein the instructions instruct a user to add water to the second concentrated mix of components and the method further comprises the step of adding water to the second concentrated mix of components to form a second immersion bath prior to immersing the at least partially coated plastic substrate in the second immersion bath.

13. A method of removing paint from a plastic substrate at least partially coated with a paint coating comprising the steps of:

providing at least one plastic substrate at least partially coated with a paint coating;

providing a kit for a user to utilize to remove paint from the plastic substrate, which is at least partially coated with a paint coating, wherein the kit comprises:

a first set of chemicals comprising: at least one aromatic alcohol; an alpha-hydroxy acid; an anionic surfactant; 2-mercaptobenzothiazole or salts thereof; and a xylene; and

instructing an end user to remove paint from the plastic substrate using the first set of chemicals;

wherein the first set of chemicals is packaged together with the instructions within the kit;

immersing the at least partially coated plastic substrate into a first immersion bath comprising the first set of chemicals wherein the first immersion bath further comprises water; and

rinsing the plastic substrate with water; and

wherein the immersing and rinsing steps remove at least a portion of the paint coating from the plastic substrate.

14. The method of claim 13 , wherein the first immersion bath comprises water in a user determined amount.

15. The method of claim 13 , wherein the first set of chemicals are concentrated and the process further comprises the step of adding water to the concentrated first set of chemicals prior to immersing the at least partially coated plastic substrate into the first immersion bath.

16. The method of claim 15 , wherein the plastic substrate comprises a plastic substrate selected from the group consisting of: nylon, polypropylene, polyphenylene oxide (PPO), polyethylene, polycarbonate, thermoplastic polyolefins, polyamide (PA), polyphenylene ether (PPE), thermoplastic urethanes, blended nylon, polyvinyl chloride, polystyrenes, and mixtures thereof.
