The use of solvents as application aids for adhesives is the classic method in formulation technology, whereby a polymer is dissolved in a suitable solvent to give a more or less effective adhesive in the form of a polymer solution. In principle all thermoplastics are suitable as polymers for this purpose.

Solution viscosities are of particular relevance for processing and applying polymer solutions as adhesives. In practice, polymers may take very long to dissolve, even in appropriate solvents or solvent mixtures. Resins (up to 50 percent) serve to increase tack and to improve adhesion and sometimes thermal stability. Additives (< 5 percent) and fillers are also used.


  • Short fixing times

  • Instantaneous high initial bonding

  • Application of adhesive and bonding of the substrates can be performed independently, at different times (solvent reactivation)

  • No solvent is involved in the actual bonding process (heat reactivation)

  • Good adhesion to a variety of substrates, particularly plastics

  • Composition can be varied, thanks to a large variety of different raw materials


  • Used in many adhesive applications in major industries (heat reactivation)

  • Adhesion of porous substrates (wet bonding)

  • Automotive industry (almost the entire interior of a car consists of laminated materials)

  • Shoe industry (bonding of sole and upper)

  • Wood and furniture industry / packaging industry (decorative or functional laminates with an extremely wide range of material pairs)

  • Construction sector (PVC pipes, PVC sheeting)

  • DIY sector (as a universal adhesive)
