Why is it important and how to do it

As it is known, surfaces are very critical for adhesion performance. The condition of the surface can be improved by preparing the surface, increasing the performance.

According to the Adhesive products preparation and repair regulation issued by the US Department of Transportation and the National Aviation Authority:

"Surface preparation before adhesion is the most important factor in the structural integrity to be formed with the tape."

An adhesive tape may fail even if the surfaces are suitable for application when adequate surface preparation is ignored. The most basic surface preparation is to clean the surfaces where adhesive tapes will be used before application. Dirt, residues, dust and other particles move by forming an unstable layer on the surfaces. These should be removed from the environment and cleaned to ensure adequate surface contact.

The most commonly used cleaning product is a 1 to 1 mixture of isopropyl alcohol (IPA) and water. Situations that may require additional surface preparation are as follows;

Heavy Oils

Heavy oil or grease should be removed with a degreaser or solvent-based cleaner, followed by IPA / water cleaning.

Wear, wear, rust

Following the sanding of the surface, cleaning with IPA / water can increase adhesion by removing wear, heavy dirt or oxidation.

Porous Materials

Porous and fibrous materials such as wood, chip or concrete should be smoothed, sealed to provide a smooth surface.

Special Materials

Special surface preparations may be required for glass and glass-like materials, copper and copper-containing metals, and plastic surfaces containing plastic or rubber compounds.
