Kestopur 205/150 H is a two-component polyurethane adhesive for the gluing of metal, wood, insulation materials and fibre composite in sandwich panel constructions in the transportation industry.

Special features

  • Solvent-free
  • Long open time
  • Paste consistency
  • Good ridge forming and stays well on vertical surfaces




Kestopur 205/150 H is a solvent-free paste, polyurethane adhesive which gives a strong, yet elastic bond. Long open time. Designed for sandwich panel manufacture. Suitable for e.g. the gluing of metals, wood, insulation materials and fibre composite.
Used in conjunction with Kestopur 200/H hardener.

Instructions for use

The surfaces to be bonded must be clean and dry. Remove dust, dirt, oxides, grease, etc. using Kiilto Cleaner 303. The properly cleaned surface can be sanded and primed to improve adhesion. Remove the sanding dust carefully prior to adhesive application. Kestopur 205/150 H resin is stirred before use. Add hardener to resin, and mix until a uniform colour is achieved. Apply adhesive one- or two-sided with a spreader or other application tool. 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 carrying out the gluing at room temperature. Adhesive's open time 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.
