How Pressure Sensitive Adhesive Tape Works

Pressure sensitive adhesive (PSA) tape offers manufacturers in many markets a range of benefits. These include:

  • Improved product durability
  • Reduced product weight
  • Lower production costs
  • Enhanced product aesthetics
  • Increased productivity

As a result, it’s understandable why PSA tape is becoming a popular choice for markets ranging from automotive to construction. Yet it’s important for these manufacturers to know how PSA tape works on different surfaces to fully anticipate its performance expectations. The Pressure Sensitive Tape Council helps explain it:

  1. If There are Contaminants

PSA tape will form an initial bond to anything that is on the surface of a given substrate.

Therefore, if there are contaminants on a surface, such as dirt, oil, rust, etc., the PSA tape will form an initial bond with those materials and not the surface underneath. This will cause the bond with the surface to not be as strong and possibly result in failure.

  1. If the Surface is Textured

When bonding to a textured surface, such as wood and textiles, the PSA tape’s adhesive contact will be strongest at only the surface’s high points.

With time and pressure, the adhesive will seep into the surface’s lower points. However, it’s important the PSA tape is thick enough to fully fill these depths.

  1. If the Surface is Curved

Curved surfaces can cause stress to the edges or bending point of the PSA tape. This can cause a de-bonding peel force, meaning the PSA tape will not properly adhere to the surface.

Understanding this characteristic will help ensure a PSA tape is chosen that can overcome these forces.
