Adhesives are substances that are used to bind or hold two or more materials together. They can be used in a variety of applications, including construction, manufacturing, packaging, and more. Adhesives are used in place of mechanical fasteners like nails and screws, or welding.

There are several different types of adhesives that can be used for edge banding, including:

• PVA (polyvinyl acetate) glue: This is a common adhesive used for edge banding because it is easy to apply and dries quickly. It forms a strong bond and is resistant to water, making it a good choice for use in humid environments.
• EVA (ethylene-vinyl acetate) glue: This is a more flexible adhesive than PVA and is often used for edge banding on curved or irregular surfaces. It is also resistant to water and heat, making it suitable for use in a wide range of environments.
• PU (polyurethane) glue: This is a more expensive option, but it forms a very strong bond and is highly resistant to water and heat. It is often used for edge banding in high-stress applications, such as in the construction of kitchen cabinets or office furniture.
• Hot melt: This is a thermoplastic adhesive that is applied in a molten state. It forms a strong bond and can be used on a variety of substrates, including wood, metal, and plastic. It is also easy to apply and dries quickly.
• Contact adhesive: This is an adhesive that is applied to both the edge banding material and the substrate, then pressed together to form a bond. It is usually used for edge banding on irregular or non-straight surfaces.

All of these adhesives have their own pros and cons, and the choice of adhesive will depend on the specific requirements of the project and the type of edge banding material being used.

How to use adhesives for edge banding

The process of using adhesives for edge banding will vary depending on the type of adhesive being used and the specific requirements of the project. However, some general steps that can be followed include:

1. Prepare the substrate: Clean and sand the edge of the substrate to ensure that it is free of dust and debris. This will ensure that the adhesive will form a strong bond.
2. Apply the adhesive: Apply the adhesive to the edge of the substrate using a brush or roller. If using a two-part adhesive like epoxy, be sure to mix the two components together before applying.
3. Apply the edge banding: Carefully align the edge banding material with the edge of the substrate and press it into place. Use a roller or other tool to ensure that the edge banding is fully in contact with the adhesive.
4. Allow the adhesive to dry: Follow the manufacturer’s instructions for drying time.
5. Trim the excess edge banding: Using a sharp blade or a specially designed edge banding trimmer, trim the excess edge banding material.
6. Sand the edge: Sand the edge to ensure that it is smooth and flush with the substrate.
7. Finish: Apply a finish to the edge banding, such as a varnish, stain or paint, to match the color of the substrate.

It’s important to note that some adhesives, like contact adhesive, are applied on both the edge banding and substrate, then pressed together to form a bond. Always check the manufacturer’s instructions and safety precautions before using any adhesive.
