Klebstoffübertragung

Klebstoffübertragung, often referred to as adhesive transfer, describes the phenomenon where a portion of an adhesive layer separates from its intended substrate and adheres to another surface. This can occur during various stages of application, handling, or assembly processes. The primary cause is a failure of adhesion between the adhesive and the substrate it was initially applied to. This failure can be due to insufficient surface preparation, contamination on the substrate, improper curing of the adhesive, or mechanical forces applied during handling or assembly that exceed the adhesive's bond strength.

The consequences of Klebstoffübertragung can range from cosmetic defects to functional failures. In manufacturing, it can lead to rejection of parts, increased rework, and potential contamination of assembly equipment. For consumers, it might result in products that do not perform as expected or appear aesthetically displeasing. Understanding the factors that contribute to Klebstoffübertragung is crucial for selecting the appropriate adhesive, preparing surfaces correctly, and controlling process parameters to ensure reliable bonding. Different types of adhesives exhibit varying tendencies for transfer, influenced by their chemical composition, viscosity, and curing characteristics.
