"Bonding PETG Plastic Strips to a Surface: A Step-by-Step Guide"

PETG (polyethylene terephthalate glycol) is a popular material used in a wide range of applications, from industrial plastics to 3D printing. When it comes to attaching PETG plastic strips to a surface, a strong and durable bond is essential to ensure the integrity and longevity of the final product. In this article, we’ll explore the best methods and materials to glue PETG plastic strips to a surface, ensuring a successful and long-lasting bond.

Preparation is Key

Before applying the adhesive, make sure the surface is clean, dry, and free of dirt, oil, or other substances that might interfere with the bonding process. If necessary, lightly sand the surface to create a rough texture that will help the adhesive adhere better.

Choosing the Right Adhesive

When selecting an adhesive, consider the type of PETG plastic strip, the surface it will be bonded to, and the environmental conditions it will be exposed to. Here are some common adhesives that work well with PETG:

  1. Acrylic adhesives: These are a popular choice for bonding PETG to various surfaces, including glass, metal, and other plastics.
  2. Epoxy adhesives: Epoxy adhesives are ideal for bonding PETG to surfaces that require high strength and resistance to heat, chemicals, or UV light.
  3. Silicone adhesives: These are suitable for bonding PETG to surfaces that require flexibility and resistance to high temperatures, such as in automotive applications.

Applying the Adhesive

Choose your preferred adhesive and follow the manufacturer’s instructions for application. Apply a small amount of adhesive to one surface, followed by the PETG plastic strip. Ensure the strip is centered and smooth out any air bubbles or excess adhesive.

Tips for Optimal Bonding

To achieve a strong and durable bond, keep the following tips in mind:

  1. Surfaces must be in good condition: Make sure the surfaces are clean, dry, and free of contaminants.
  2. Apply even pressure: Use a clamp or flat surface to apply even pressure to the PETG strip while the adhesive sets.
  3. Avoid twisting or flexing: Minimize movement or twisting of the PETG strip during the bonding process to prevent adhesive failure.
  4. Allow the adhesive to set: Let the adhesive dry according to the manufacturer’s instructions, typically 15-30 minutes, depending on the adhesive type.

Common Issues and Troubleshooting

If the bond doesn’t seem to be sticking, check for one or more of the following:

  1. Inadequate preparation: Make sure the surfaces are clean, dry, and free of contaminants.
  2. Insufficient pressure: Check if the pressure applied during the bonding process was sufficient.
  3. Incorrect adhesive: Choose a different adhesive that is suitable for the PETG plastic strip and the surface it will be bonded to.

By following these guidelines, you’ll be well on your way to successfully gluing PETG plastic strips to various surfaces. Remember to select the right adhesive for the job, prepare the surfaces properly, and apply even pressure to ensure a strong and durable bond.

It's a steel surface that has been corroded with acid then "sealed" with boiled linseed oil.

The strip I need to glue onto it are led strip channels, the material is PETG, it goes on the backside of this sign

I have pretty much no tools on site. Degreaser and sand paper are an option. But I am worried about using a degreaser not to "damage" the front side of the sign. It's also in a hot ocean side climate.

I was think acrylic adhesive or two component epoxy but I am very much out of my knowledge range here

Thank for any advise!
