Kestopur 205/60
2-component solvent-free pu-adhesive

Kestopur 205/60 is a two-component polyurethane adhesive for the gluing of metal, wood and insulation materials, as well as fibre composites in sandwich panel constructions for the transportation industry.

Special features

  • Solvent-free
  • Excellent adhesion to metals
  • Long open time and short pressing time
  • Suitable for both automatic and manual application




Kestopur 205/60 gives a strong, yet elastic bond. A special characteristic of the adhesive is its ductile adhesion on metal surfaces. Suitable for automatic application. Used in conjunction with Kestopur 200/S hardener. Adhesive is compliant with M1 Emission Classification of Building Materials. Suitable for e.g. the gluing of metals, wood, insulation materials and fibre composite. Typically used for the gluing of sandwich panels used in thermo-insulated trucks.

Instructions for use

The surfaces to be bonded must be clean and dry. Remove oxides by sanding, and grease and other dirt with Kiilto Cleaner 303. The properly cleaned surface can be sanded and then primed to improve adhesion. Remove the sanding dust carefully prior to adhesive application. Stir resin before use. Add hardener to resin, and mix until a uniform colour is achieved. Apply the adhesive on one or both sides of the materials to be bonded. Fresh adhesive stains are removed with a dry cloth and surfaces are wiped with Kiilto Cleaner 303 or 2K Cleaner. Hardened adhesive can only be removed by mechanical means. We recommend gluing at room temperature. The open time of the adhesive depends on temperature and air humidity. However, the gluing can be carried out at lower temperatures (even at +10 °C), but then the pressing time will be significantly longer and spreading properties will suffer. A higher pressing temperature will shorten the pressing time.
