Haftklebstoffen
Haftklebstoffe, often translated as pressure-sensitive adhesives (PSAs), are materials that form a bond when light pressure is applied. They remain permanently tacky at room temperature and do not require activation by water, solvent evaporation, or heat. The adhesive properties are a result of a balance between cohesion, the internal strength of the adhesive, and adhesion, the ability of the adhesive to bond to a surface. PSAs are typically formulated as liquids or solids that are then applied to a backing material.
The key characteristic of a Haftklebstoff is its ability to adhere immediately to a surface upon contact
