What Surfaces Does E6000 Not Stick To?

E6000, a popular adhesive known for its versatility and strong bonding capabilities, does have a few limitations when it comes to certain surfaces. Understanding these limitations can help users determine when it is appropriate to use E6000 and when alternative options may be necessary.

One of the surfaces that E6000 may struggle to adhere to is silicone. Silicone is a rubber-like material that is resistant to many types of adhesives. While E6000 may initially bond to silicone, over time, the bond can weaken and fail. So it’s better to avoid using E6000 on silicone surfaces if you want a long-lasting bond.

Similarly, E6000 may not stick well to polyethylene and polypropylene plastics. These plastics have low surface energy, making it difficult for adhesives to form strong bonds. If you need to bond polyethylene or polypropylene, it is best to choose an adhesive specifically designed for these materials.

Another surface that E6000 may not adhere to effectively is Teflon. Teflon is a nonstick material commonly used in cookware and other applications where low friction is desired. The nonstick properties of Teflon make it challenging for adhesives like E6000 to form a secure bond. It’s recommended to explore alternative adhesives when working with Teflon surfaces.

E6000 may also struggle to stick to certain types of metals that have high levels of oil or grease on their surfaces. Before applying E6000 to metal surfaces, it’s important to ensure that the area is clean and free from any contaminants that could interfere with the adhesive’s bonding ability.

Additionally, E6000 may not be suitable for bonding certain fabrics or materials with high levels of flexibility or stretchiness. The adhesive may not provide the necessary flexibility and durability required for these applications. It’s advisable to test the adhesive on a small, inconspicuous area of the fabric or material before committing to a larger project.


Polyethylene is a versatile and widely used thermoplastic polymer that has numerous applications in various industries. It is known for its low cost, durability, and chemical resistance, making it a preferred choice for packaging, containers, pipes, and toys.

However, when it comes to adhesive bonding, polyethylene presents a challenge. This is due to its unique molecular structure and surface properties. Polyethylene consists of long chains of carbon atoms with hydrogen atoms bonded to them. These chains are highly non-reactive and have a low surface energy, which means they do not readily form bonds with other substances.

In addition to its low surface energy, polyethylene also has a smooth and slippery surface. This lack of surface irregularities or roughness reduces the contact area between the adhesive and the polyethylene surface, making it harder for the adhesive to adhere effectively.

One of the main challenges is silicone’s low surface energy. This means that silicone has a weak attraction to other materials, making it difficult for adhesives to form a strong bond. The low surface energy prevents the adhesive from spreading evenly across the surface and achieving good wetting, resulting in a weaker bond.

Another challenge is silicone’s lack of chemical reactivity. Silicone is chemically inert, meaning it does not readily react with other substances. This poses a challenge for adhesives trying to create strong chemical bonds with silicone surfaces.

Temperature resistance is another consideration when selecting an adhesive for silicone bonding. Silicone is known for its high temperature resistance, which can make it challenging to find an adhesive that can withstand these conditions. While E6000 is a general-purpose adhesive, its temperature resistance may not be sufficient for bonding silicone surfaces exposed to high temperatures.

In addition to these challenges, the flexibility of silicone can also pose difficulties for adhesives. Silicone is a flexible material that can undergo significant deformation without losing its shape or properties. This flexibility can make it challenging for adhesives to maintain a strong bond over time, especially if the bonded components are subject to frequent movement or stress.

To overcome these challenges, there are some potential solutions available. Properly preparing the silicone surface is crucial for improving bond strength. This includes thorough cleaning of the surface to remove any dirt, dust, or oils that may hinder adhesion. Additionally, using an appropriate primer specifically designed for bonding silicone can significantly enhance the adhesion properties.

Specialized silicone adhesives are also available on the market. These adhesives are formulated to overcome the challenges associated with silicone’s low surface energy and lack of reactivity. They often have enhanced wetting properties and can provide a stronger and more durable bond.

In some cases, using mechanical fasteners such as screws or clips alongside adhesive bonding can help improve the overall strength of the bond. This approach takes advantage of silicone’s flexibility while providing additional support and stability.


Rubber is a remarkable material that offers elasticity, durability, and resistance to heat and chemicals. It can be found in various forms, including natural rubber, synthetic rubber, and different types of elastomers. Used extensively in industries such as automotive, construction, and manufacturing, rubber proves its versatility time and time again. However, when it comes to bonding rubber surfaces, not all adhesives are created equal.

Enter E6000, a popular adhesive known for its strong bonding capabilities. While it excels at bonding many materials, rubber poses a unique challenge. Rubber’s low surface energy means it lacks reactive sites for adhesives to form a robust connection. Unfortunately, this is where E6000 falls short.

The difficulty lies in E6000’s struggle to effectively penetrate the surface of rubber. As a result, adhesion is weakened. To compound matters, rubber surfaces often harbor oils or other substances that act as a barrier between the adhesive and the rubber itself. This less-than-ideal situation makes it challenging to achieve a secure bond.

But fret not. There are strategies to overcome these obstacles. By properly preparing the rubber surface through thorough cleaning and using a primer specifically designed for bonding rubber, the effectiveness of E6000 (or any adhesive of your choice) can be significantly enhanced.

However, if you’re seeking an exceptionally strong bond between rubber and another material, it’s worth exploring specialized adhesives formulated explicitly for bonding rubber. These magical potions possess unique properties that enable them to create stronger bonds with rubber surfaces.

Foam Materials

Foam materials are like the chameleons of the material world – versatile, lightweight, and oh-so-comfortable. But when it comes to sticking them together, things can get a little tricky. These spongy substances have low surface energy and a porous nature that make them challenging to bond. That’s where adhesives like E6000 come in, but even this superhero adhesive has its limits.

Let’s dive into the foamiverse and explore some foam materials that might give E6000 a run for its money:

  • Polyethylene Foam: This closed-cell foam is a go-to for cushioning and insulation. Its smooth surface and non-porous nature make it a tough nut to crack for adhesives. While E6000 can give it a good initial stick, it may not last long or hold up reliably.
  • Expanded Polystyrene Foam (EPS): Lightweight and used in packaging and insulation, EPS foam is as smooth as a baby’s bottom. But that smoothness, combined with its low surface energy, can make it a real challenge for adhesives like E6000 to create a secure bond. Plus, the solvent-based nature of E6000 can actually damage EPS foam, melting it away like an ice cream cone on a hot summer day.
  • Polyurethane Foam: Soft and bouncy, polyurethane foam is the stuff of cushions and upholstery dreams. But its open-cell structure poses a problem for adhesive bonding. It loves to gobble up liquids, making it difficult for E6000 to get a grip. That’s why specialized adhesives formulated specifically for polyurethane foam are the way to go.
  • Silicone Foam: When it comes to heat resistance and flexibility, silicone foams take the cake. But their smooth and non-porous surface makes them just as slippery for adhesives like E6000. To keep silicone foam stuck together, it’s best to explore alternative adhesive options designed specifically for silicone-based materials.
