How Bevelled Edges Can Cause Debonding Issues for Edge Banding159

As a reputable edge banding strip manufacturer in China, we would like to address a common issue that can arise when using edge banding: debonding caused by bevelled edges. Debonding occurs when the edge banding separates from the substrate, resulting in a compromised finish and reduced durability of the furniture.

When an edge with a bevelled angle is covered with edge banding, it creates a gap between the substrate and the edge banding. This gap can become a weak point, especially when subjected to stress or moisture. As the furniture piece is handled or experiences environmental changes, the edge banding can gradually lift away from the substrate, leading to debonding.

There are several factors that can contribute to debonding caused by bevelled edges:
Type of adhesive: Some adhesives are less effective on bevelled surfaces due to the reduced contact area between the adhesive and the substrate.
Edge banding thickness: Thicker edge banding can provide more stability and reduce the likelihood of debonding. However, it is important to ensure that the edge banding is not too thick, as it can create excessive tension.
Substrate material: Substrates with a rough or uneven surface can make it difficult to achieve a strong bond with edge banding, especially on bevelled edges.

To minimize the risk of debonding due to bevelled edges, we recommend the following measures:
Choose a suitable adhesive: Select an adhesive that is specifically designed for use on bevelled surfaces and that is compatible with the substrate material.
Use thicker edge banding: Consider using edge banding that is at least 1.5 mm thick to provide additional stability.
Prepare the surface properly: Ensure that the substrate surface is clean, dry, and free of any contaminants before applying the edge banding.
Apply pressure: Apply sufficient pressure to the edge banding during the bonding process to ensure a strong bond. This can be done using a press or vacuum system.

By following these recommendations, you can reduce the likelihood of debonding caused by bevelled edges and ensure the durability of your furniture pieces. If you encounter any issues with debonding, do not hesitate to contact our experienced team for assistance.
