Do Edge Bands Easily Degum After Sealing?154

Edge banding is a crucial part of furniture manufacturing and finishing. It provides a clean, finished look to the edges of panels and helps to protect them from moisture and damage. However, one common concern about edge banding is whether or not it is prone to degumming, or separating from the panel. In this article, we will explore the factors that can contribute to edge band degumming and provide tips to help prevent it.

Understanding Edge Band Adhesion

Edge band adhesion is the key to preventing degumming. Adhesives are used to bond the edge band to the panel, and the strength of this bond will determine how well the edge band stays in place. The type of adhesive used, as well as the surface preparation of the panel and edge band, can all affect adhesion.

Common Causes of Edge Band Degumming

There are several common factors that can contribute to edge band degumming:
Inadequate surface preparation: If the panel and edge band are not properly cleaned and prepared before applying the adhesive, it can lead to poor adhesion and degumming.
Incorrect adhesive selection: Different types of adhesives are designed for different applications. Using the wrong adhesive for the type of panel and edge band can result in insufficient adhesion.
Improper adhesive application: The adhesive must be applied evenly and in the correct amount. Too little adhesive can lead to poor adhesion, while too much adhesive can cause the edge band to wrinkle or buckle.
Excessive moisture: Exposure to excessive moisture, such as from spills or high humidity, can weaken the adhesive bond and cause degumming.
Incorrect storage or handling: Improper storage or handling of edge banded panels can put stress on the adhesive bond, leading to degumming.

Tips to Prevent Edge Band Degumming

To prevent edge band degumming, you should follow these tips:
Proper surface preparation: Clean and de-grease the panel and edge band surfaces before applying the adhesive.
Choose the right adhesive: Select an adhesive that is specifically designed for the type of panel and edge band you are using.
Apply the adhesive correctly: Apply the adhesive evenly and in the correct amount.
Maintain proper environmental conditions: Avoid exposing edge banded panels to excessive moisture or temperature fluctuations.
Handle and store edge banded panels carefully: Avoid putting undue stress on the adhesive bond during handling or storage.

Conclusion

Edge band degumming is a common problem that can be caused by a variety of factors. By understanding the causes of degumming and following the tips outlined in this article, you can help to prevent this problem and ensure that your edge banded furniture looks its best for years to come.
