The adhesive surface is a critical factor in adhesive application and can affect the strength and durability of the bond. An optimum adhesive surface is clean, dry, free from oils and greases and rough or porous areas. Too small an adhesive area can result in insufficient adhesion, while too large an area will result in unnecessary adhesive application.
It is also important to note that the type of adhesive surface can affect the behaviour of the adhesive. For example, porous or uneven surfaces can soak up the adhesive and affect the strength of the bond. A smooth, flat surface, on the other hand, provides the adhesive with a larger contact area and better adhesion.
When choosing the right adhesive for a particular application, it is important to consider the type of materials to be bonded and the properties of the adhesive surface. Some adhesives are better suited for use on smooth, flat surfaces, while others are designed for use on porous or uneven surfaces.
Overall, the adhesive surface is an important factor in adhesive application that is often overlooked. Careful preparation of the surface and selection of the right adhesive for the specific materials and requirements can help ensure a strong, durable bond.
