Kestopur 1 C 10
1-component polyurethane adhesive

Kestopur 1 C 10 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 10 is a moisture curing, one-component, polyurethane adhesive with low viscosity. Moisture curing. Strong foam building. Suitable, for example, for the gluing of wood, metal, insulation materials and fibreglass laminate. Preliminary adhesion tests must be carried out prior to full scale application. Due to low viscosity Kestopur 1 C 10 is ideal for automatic application. Note that some amount of gas builds in the curing reaction, so ensure that one of the surfaces to be bonded is permeable. Does not contain solvents. Adhesive is compliant with the M1 Emission Classification for Building Materials.

Instructions for use

The surfaces to be bonded must be clean and dry. Remove dust, dirt, oxides, grease, etc. with Kiilto Cleaner 303 and/or by sanding. The 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. Hardened adhesive can only be removed 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.
