Kestopur PL 250/40
2-component solvent-free pu-adhesive
Kestopur PL 250/40 is a 2-component polyurethane adhesive for the gluing of metal, wood and insulation materials as well as fiber composite in sandwich panel constructions for the transportation and marine industry.
- Very strong bond
- Excellent adhesion to various materials
- Paste formula
Kestopur PL 250/40 gives a strong, yet an elastic bond. Due to its paste formula, it is ideal for trowel application for walls and ceilings. Used in conjunction with Kestopur 200/S hardener. Kestopur PL adhesives are fire classified according to marine industry's IMO FTPC, Part 5 and have a MED certificate (Wheel-mark). Adhesive has M1-emission classification for building products.

The surfaces to be bonded must be clean and dry. Remove oxides by sanding, grease etc. dirt with Kiilto Cleaner 303. First stir Kestopur PL 250/40 resin. Then add the hardener carefully stirring. Apply the adhesive using a roller, spatula or other application tool on one or both sides of the materials to be bonded. Remove fresh adhesive stains with a dry cloth and clean the surfaces with Kestopur Cleaner 302, acetone or xylen. Cured adhesive can be removed only by mechanically means. We recommend gluing at room temperature. Gluing at a lower temperature is possible ( even +5–10 °C), but will lead to weaker spreading properties and to significantly slower curing process.
