| Rubber | No |
| Nylon | No |
| Expanded Vinyl or StyrofoamTM | No |
| Porous surfaces (e.g. stone) | No |
| Painted surfaces (e.g. drywall) | No |
Gorilla Glue’s formulation and bonding properties make it incompatible with these materials and surfaces. Plastics, rubber, nylon, and expanded vinyl do not provide a suitable surface for Gorilla Glue to bond with. Additionally, porous surfaces like stone or painted surfaces like drywall can absorb the adhesive and result in a weaker bond.
It’s important to note that although Gorilla Glue remains flexible after drying, it is not waterproof and cannot fill cracks or holes. It also cannot be applied over paint as it will remove the paint. However, it can bond with a wide range of other materials such as wood, metal, ceramics, concrete, glass, leather, paper, cloth, foam, and vinyl.
Non-Porous Surfaces
Gorilla Glue is a popular adhesive known for its ability to bond with various materials. However, it cannot stick to non-porous surfaces. This is because non-porous surfaces lack microscopic gaps for the glue to seep into and form a strong bond. Instead, the glue will simply sit on the surface and eventually dry, resulting in a weak bond.
Polyurethane is one of the key components of Gorilla Glue, responsible for creating a durable bond. However, this ingredient requires moisture to cure and form a strong bond. Non-porous surfaces do not provide enough moisture, making it difficult for the glue to work effectively.
Moreover, Gorilla Glue is not compatible with materials like plastic, rubber, nylon, or Teflon-coated surfaces. It also does not work well on porous surfaces such as stone or drywall. This is because these materials may contain additives that prevent the glue from creating a strong bond.
In addition, Gorilla Glue is not waterproof and should not be used to repair cracks or holes. It will also remove any paint it comes into contact with. These limitations make it unsuitable for use on non-porous surfaces.
Polyethylene and Polypropylene Plastics
Surprisingly, yes. These types of plastics have a low surface energy, making them notoriously difficult to bond with adhesives. However, gorilla glue is uniquely suited for these materials due to its expanding properties when drying and its high bond strength. But before you start bonding your plastic pieces, there are some important factors to consider.
Surface Preparation:
Preparing the surface is key when using gorilla glue on polyethylene and polypropylene plastics. The low surface energy of these plastics makes it challenging for the glue to create a strong bond.
To increase the surface energy, it is recommended to roughen the plastic using sandpaper or a file. This creates tiny gaps on the surface, allowing the glue to adhere better.
Amount of Glue:
Since gorilla glue expands when drying, it’s crucial to use a smaller amount compared to other adhesives.
Using too much can cause overflow and create a messy bond. Instead, use a small amount and spread it evenly across the surface.
Drying Time:
Gorilla glue sets in just 10-45 seconds, but it takes 24 hours to reach its full strength. To ensure a strong bond, hold the pieces together for at least 2 hours before releasing them. For optimal results, allow the glued item to sit undisturbed for 24 hours.
Types of Gorilla Glue:
There are multiple types of gorilla glue available, including original, super glue, and wood glue.
For bonding with plastics, original gorilla glue is best as it has an impressive bond strength of 4250 PSI and can withstand harsh environments.
Alternatives:
While gorilla glue is effective for bonding with polyethylene and polypropylene plastics, there are other options available as well.
Super glue or cyanoacrylate can also bond with plastics, but they may damage the surface when removed. It’s important to consider the durability and potential damage of the adhesive before using it on plastic.
Flexible Materials
When it comes to glue, Gorilla Glue is a top choice for its strong adhesive properties. However, not all materials are compatible with this powerful glue. In fact, there are several types of flexible materials that do not bond well with Gorilla Glue. These include polyethylene and polypropylene plastics, silicone rubber, Styrofoam™, expanded polystyrene, and any foam with high oil content.
Polyethylene and polypropylene plastics are commonly found in everyday products like plastic bags, food containers, and bottles. But due to their low surface energy, Gorilla Glue struggles to bond with these materials. This is because the molecules in these plastics do not easily attract or bond with other materials.
Another material that poses a challenge for Gorilla Glue is silicone rubber. This non-porous material has a low surface energy, making it difficult for the glue to adhere to it. Similarly, both Styrofoam™ and expanded polystyrene are porous materials that do not bond well with Gorilla Glue.
Additionally, any foam with high oil content can also be problematic for Gorilla Glue. The oil in the foam creates a barrier that prevents the glue from properly bonding with the surface, resulting in a weak bond.
There are alternatives to Gorilla Glue for these materials. Some options include 3M Super 77 Multipurpose Adhesive, Dow Corning High Strength Silicone Adhesive, Loctite PL 300 Foam Board Adhesive, Bostik Foamtac Plus Adhesive, and 3M 90 Spray Adhesive.
