Kestopur 203/15 green
Kestopur 203/15 green is a 2-component polyurethane adhesive for the gluing of metal, wood and insulation materials, as well as fiber composites in sandwich panel constructions for the transportation industry.
- Suitable for machine application with multicomponent systems
Kestopur 203/15 green gives a strong, yet an elastic bond. Ideal for automatic application. Special characteristics of the adhesive is its tough grip on metal surfaces and lower viscosity than normally with Kestopur-adhesives. Suitable for e.g. gluing of metals, wood, insulation materials and fiber composite. Used in conjunction with Kestopur 200/S hardener.

The surfaces to be bonded must be clean and dry. Remove oxides by sanding, and grease etc. 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 Kestopur 203/15 green -resin before use. Add Kestopur 200/S hardener to resin and mix until a uniform colour is achieved. Apply the adhesive with a spreader or other application tool on one or both sides of the materials to be bonded. Fresh adhesive stains are removed with a dry cloth and then surfaces are cleaned with Kiilto Cleaner 303 or Kiilto Cleaner 302. Cured adhesive can be removed only 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. Higher pressing temperature will shorten the pressing time.
