White Spots on the Back of Edge Banding: Causes and Solutions100

As a leading manufacturer of edge banding in China, we understand the importance of providing high-quality products to our customers. However, we have recently received inquiries regarding the appearance of white spots on the back of our edge banding. This issue can be frustrating, but we want to assure our customers that we are committed to finding solutions.

Through extensive research and testing, we have identified several potential causes for the white spots on the back of edge banding:

1. Moisture Absorption:

* Edge banding can absorb moisture during storage or transportation, which can lead to the formation of white spots.
* Ensure that edge banding is stored in a dry and well-ventilated area.
* Use moisture-resistant coatings to prevent moisture absorption.

2. Glue Migration:

* The adhesive used to bond edge banding to substrates can sometimes migrate to the back of the banding, forming white spots.
* Select high-quality adhesives with low migration potential.
* Apply the adhesive evenly to the edge banding to minimize migration.

3. Contaminants in Raw Materials:

* Impurities or contaminants in the raw materials used to manufacture edge banding can cause white spots.
* Source raw materials from reputable suppliers.
* Employ quality control measures to inspect raw materials before production.

4. Production Process Errors:

* Variations in temperature, pressure, or curing time during the production process can lead to white spots.
* Optimize production parameters and ensure consistency throughout the process.
* Calibrate and maintain equipment regularly.

To address these causes, we have implemented several measures:* We have upgraded our storage facilities to maintain optimal humidity levels.
* We have sourced high-quality adhesives with low migration properties.
