2-component solvent-free pu-adhesive
Kestopur 205/50 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.
- Strong, durable
- Suitable for automatic application
Kestopur 205/50 gives a strong, yet elastic bond. Adhesive has a long open time compared to the pressing time. Kestopur 205/50 is ideal also for automatic application. Used in conjunction with Kestopur 200/S hardener. Adhesive is compliant with M1 Emission Classification of Building Materials. Kestopur 205/50 is used for the gluing of metal, wood, insulation materials and fibre composite.

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 primed to improve adhesion. Remove the sanding dust carefully prior to adhesive application. Stir Kestopur 205/50 resin before use. Add Kestopur 200/S hardener to the 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 Kiilto Cleaner 302. 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.
