Adhesive Application and Methods

Proper application of adhesive is crucial to ensure strong and long-lasting bonding. The surfaces to be glued must be clean, grease-free, and smooth to allow better penetration of the adhesive. Emulsion-based adhesives contain tiny particles that help create a strong bond between surfaces. These adhesives are commonly used in furniture assembly, particleboard lamination, and MDF bonding. In some lamination processes, the adhesive may need to be diluted. However, the dilution process should be done carefully to maintain the adhesive’s bonding strength.

How to Apply Adhesive?

Before applying the adhesive, surface cleanliness is essential. Dust, grease, or dirt can weaken the adhesive's grip, reducing the expected durability. During application, applying the adhesive to only one surface is usually sufficient. A brush is the most practical tool for application, but it can also be applied using a steel spatula, similar tools, or even by hand.

For porous surfaces, adhesive application may take longer. In such cases, the parts should be joined quickly after applying the adhesive. The bonded parts must be kept in place until the adhesive fully sets, and ideal temperature conditions should be ensured. Maintaining an ambient temperature 10-15 degrees above room temperature helps the adhesive cure more effectively. At room temperature, full curing can take up to 20 hours.

The viscosity and consistency of the adhesive should be adjusted according to the intended use. Dilution is not recommended for thick surfaces, as reducing the viscosity may weaken the bonding strength. If dilution is necessary, the ratio should not exceed 30%.

By using the correct application techniques, it is possible to maximize the strong bonding properties of the adhesive. Choosing the appropriate method for the material being bonded ensures a long-lasting and durable result.
