Tape leakage or crawling is a common issue encountered during adhesive tape application, and it can be caused by several factors. Understanding these causes and how to prevent them is essential for ensuring optimal performance.

Tape Crawling from Over-Compression of Tape

The most common reason we see tape crawling or leakage is from the over-compression of the tape during application. When too much pressure is applied, it can force the adhesive out of the tape, leading to unwanted movement or seepage.

To avoid this, it’s crucial to adhere to the recommended application pressure guidelines provided by the tape manufacturer. Applying the right amount of pressure ensures a secure bond without causing the adhesive to leak or crawl. Capital tape provides specific pressure guidelines for all of its tape products, however, if you are unsure how much compression should be applied to any specific adhesive, contact us before applying your tape.

Tape Crawling Due to Poor Quality or Expired Adhesive

A poor quality tape can frequently result in poor performance of the adhesive. The most common complaint of adhesives of poor quality is inadequate bonding within the application. Inadequate bonding can also lead to issues such as tape leakage or crawling out of the application.

Another possible cause of tape crawling is an expired adhesive. Even the highest quality tapes have a shelf-life, which can be impacted by storage environment, temperature, and moisture. If an adhesive is beyond its shelf life, it should be discarded or exchanged. Using an expired adhesive will also result in poor and inadequate bonding, which can lead to gaps or cause the adhesive to leak and crawl out of its application.

It is important to ensure that the adhesive is both suitable for the specific application and within its specified shelf life. This helps maintain the integrity of the bond and prevents any issues related to tape movement.

Incorrect Adhesive for the Application Can Cause Tape Crawling

Selecting the right adhesive for the specific application is critical. There is a reason that specific tapes are manufactured for specific industries and uses and in many cases, must meet certain minimal certifications. Using an adhesive that is not designed for the particular substrate or environment can cause tape leakage, crawling, and seal failure. To prevent this, it’s important to match the adhesive properties with the surface requirements. Ensuring compatibility between the adhesive and the substrate will result in a more stable and reliable bond, preventing any unintended movement of the tape.

Avoiding over-compression, ensuring the use of only fresh adhesives, and using the correct adhesive type for the application will prevent tape leakage and crawling. By following these guidelines, you can achieve a more effective and durable tape application.
