Kestopur 1 C 5
1-component polyurethane adhesive

Kestopur 1 C 5 is a one-component polyurethane adhesive for the gluing of metals and insulation materials in sandwich panel manufacture in the construction panel industry.

Special features

  • Solvent-free
  • No fillers
  • Suitable for automatic application
  • Suitable for SIP panel industry




Kestopur 1 C 5 is a moisture curing one-component polyurethane adhesive with low viscosity. Strong foam building. Suitable for gluing for example wood, metal, insulation materials and glass fibre laminate. Preliminary adhesion tests must be carried out prior to full scale application. Due to low viscosity Kestopur 1 C 5 is ideal for automatic application. Note that a small amount of gas builds in the curing reaction, so ensure that one of the surfaces to be bonded is permeable. Does not contain solvents.

Instructions for use

The surfaces to be bonded must be clean and dry. Remove oxides, grease etc. dirt with Kiilto Cleaner 303 or/and by sanding. Properly cleaned surface can be sanded to improve adhesion. Remove the sanding dust carefully prior to adhesive application. Apply the adhesive in an even layer on one of the surfaces. Water sprayed (5–10 g/m 2 ) on the adhesive layer shortens the pressing time. Remove fresh adhesive stains with a dry cloth and clean the surfaces with acetone or xylene. Cured adhesive can be removed only by mechanical means. We recommend using adhesive at room temperature. However, the gluing can be carried out at lower temperatures (even at +5–10 °C), but then the curing time will be much longer.
