Different Types of Materials That Require Stronger Adhesive Bonds

Adhesive bonding is a common method of joining materials together. However, not all materials are created equal and some require stronger adhesive bonds than others. In this article, we will explore the different types of materials that require stronger adhesive bonds than super glue.


Metal surfaces can be smooth and non-porous, making it difficult for traditional adhesives to form a strong bond. In these cases, epoxy or cyanoacrylate (super glue) may be used as they can provide a strong and durable bond. However, for heavier-duty applications or metals with oily surfaces, a stronger adhesive like epoxy is necessary. Epoxy is commonly used in the automotive and aerospace industries for bonding metal parts together.


Plastic materials can be challenging to bond because they come in different compositions and surface energies. While super glue may work for small plastic pieces, larger or heavier ones may require a more robust adhesive like cyanoacrylate. For example, in the electronics industry, cyanoacrylate is often used to bond plastic components together.


Wood is a porous material that can absorb some adhesives, leading to weaker bonds. Additionally, wood expands and contracts with changes in temperature and humidity, which can cause the bond to weaken over time. That’s why woodworkers often choose stronger adhesives like polyurethane glue or epoxy for their projects. Polyurethane glue is particularly useful for outdoor furniture as it is waterproof and resistant to temperature changes.


Due to its smooth surface and non-porous nature, traditional adhesives may not be effective in forming a strong bond with glass. Super glue is not recommended for bonding glass as it can create a brittle bond that may break easily. In these cases, specialized glass adhesives such as UV-curing adhesive or silicone adhesive are often used to ensure a strong and durable bond.


Ceramics are notoriously difficult to bond due to their high surface energy and low porosity. Super glue is not recommended for ceramic bonding applications as it may not provide a strong enough bond. Instead, ceramic adhesives like epoxy or cyanoacrylate with added ceramic fillers are often used. These fillers enhance the adhesive’s ability to bond with ceramic surfaces.
