I found some glues that seem to work really well (and are really strong) for gluing PETG to other materials and PETG to itself. I have been gluing PETG to steel.

For a thin liquid crazy-glue-fast setting:

Loctite SF770 activator-You need to use this for PETG because it is a low-energy plastic.



For epoxy fans, I use JB Weld Plastic Bonder. You have to hold the parts together for about 30 minutes before it sets up. I get it at Home Depot. To mix the epoxy, I use a Q-tip with one end cut off and use an old piece of scrap paper to mix it on. Q-tips are cheap, especially at the big box stores.

There are a few glues that work well for gluing PETG to metal. These include:

• Super glue: Super glue is a fast-acting adhesive that can be used to bond a variety of materials, including PETG and metal. However, it is not as strong as some other glues, and it may not be suitable for applications where the bond needs to be very strong.
• Polyurethane glue: Polyurethane glue is a more durable adhesive that is better suited for applications where the bond needs to be strong. It is also waterproof and heat-resistant, making it a good choice for outdoor applications or applications where the bond will be exposed to moisture or heat.
• Epoxy: Epoxy is a very strong adhesive that is also waterproof and heat-resistant. It is a good choice for applications where the bond needs to be very strong and durable. However, it is also the slowest-drying glue on this list.
• JB Weld: JB Weld is a high-strength epoxy that is specifically designed for bonding metal. It is very strong and durable, and it can be used to repair or create strong bonds in a variety of applications.

When choosing a glue for PETG to metal, it is important to consider the following factors:

• The strength of the bond: The glue should be strong enough to hold the PETG and metal together under the expected stresses.
• The durability of the bond: The glue should be durable enough to withstand the elements and other environmental factors.
• The speed of the bond: The glue should dry quickly enough to allow the parts to be assembled without the glue dripping or running.
• The cost of the glue: The glue should be affordable and available at a local hardware store or online retailer.

Based on these factors, the best glue for PETG to metal is polyurethane glue. It is strong, durable, and dries quickly. It is also relatively affordable and easy to find.

No matter which glue you choose, be sure to follow the instructions carefully to ensure a strong and durable bond.

The main difference in superglue formulations is the type of cyanoacrylate used. The most common types are:

• Ethyl cyanoacrylate: This is the standard type of superglue and is the most versatile. It is strong and bonds to a variety of materials, including wood, plastic, metal, and glass.

• Methyl cyanoacrylate: This type of superglue is stronger than ethyl cyanoacrylate and is better suited for bonding metal and other tough materials. However, it is not as versatile and can be more difficult to work with.

• Butyl cyanoacrylate: This type of superglue is the strongest type of superglue and is used for medical applications. It is not as versatile as ethyl cyanoacrylate and can be difficult to work with.

Other factors that can affect the formulation of superglue include:

• Viscosity: The viscosity of the glue determines how thick or thin it is. Low-viscosity glues are easier to apply to vertical surfaces and porous materials, while high-viscosity glues are stronger and better suited for bonding large areas.
• Curing time: The curing time is the amount of time it takes for the glue to dry and become fully bonded. Fast-curing glues are convenient for quick repairs, while slow-curing glues give you more time to work with the bond.
• Temperature resistance: Some superglues are more resistant to heat and cold than others. This is important to consider if you are using the glue in an environment with extreme temperatures.
• Other additives: Some superglues may contain other additives, such as UV inhibitors or anti-blooming agents. UV inhibitors protect the glue from sunlight, while anti-blooming agents prevent the glue from forming a white film on the surface.

When choosing a superglue, it is important to consider the specific application and the materials you are bonding. The best way to do this is to read the product label carefully and follow the instructions.

Here are some additional tips for choosing a superglue:

• If you are bonding two smooth surfaces, such as glass or metal, you can use a low-viscosity glue.
• If you are bonding two porous surfaces, such as wood or fabric, you can use a high-viscosity glue.
• If you need a quick-drying glue, choose a fast-curing formula.
• If you are working in an environment with extreme temperatures, choose a glue that is temperature-resistant.
• If you are concerned about the glue dripping or running, choose a glue with a slow-curing formula.
