SUMMARY

This discussion focuses on effective methods for adhering transparent PET sheets using solvent-based adhesives. Users reported that chloroform and dichloromethane resulted in opaque white fog on the PET surfaces. A recommended solution involves using potassium hydroxide (KOH) in a concentration of 20% to 80% to achieve a clear bonding result. Caution is advised due to the harmful nature of KOH, and users are encouraged to explore methods for creating a homogeneous solution with the solvents.

PREREQUISITES
  • Understanding of polymer chemistry, specifically PET properties
  • Familiarity with solvent-based adhesives and their applications
  • Knowledge of handling hazardous materials like potassium hydroxide
  • Experience in creating homogeneous solutions in chemical applications
NEXT STEPS
  • Research the properties and applications of potassium hydroxide in adhesive formulations
  • Explore alternative non-branded solvents for bonding PET sheets
  • Learn about the effects of viscosity on adhesive performance
  • Investigate safety protocols for handling and using hazardous chemicals in adhesive applications
USEFUL FOR

This discussion is beneficial for chemists, materials scientists, and professionals in manufacturing or crafting who are looking to optimize adhesive techniques for PET materials.

Hi all! I am searching for solvent based liquid glue for adhering 2 transparent PET sheets together. I tried chloroform and dichloromethane, the PET sheets were adhered but resulting of opaque white fog on my transparent PET sheets. Could someone please advice me another nonbranded chemical liquid to adhere them? I am looking for a nice clear bonding result.

I used to face the same problem as you are.Of course you can't adhered pet material with chloroform or even dichloromethane without facing the whiten surface cases,You have to combine them with other material which reduce the viscocity to get the best result.I used to use potassium hydroxide by 20 to 80 percentage,and it got the best results.but please careful since this's a harmful substances,hope this helpful for you.
 
potassium hydroxide? You do mean solid KOH flakes,don't you. I am not sure that it will dissolve in either choloroform or dicholoromethane,even with heating. The KOH powder will surely inhibit the solvent property of the choloroform,if applied in the form of such suspension,won't it. Could you please tell me how did you have a homogene solution of the liquid choloroform and the solid KOH? Or did you have a specific way to apply them to get a nice bonding result?
