Instructions and Safety
Instructions for use

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 305/15 -resin before use. Add Kestopur 200/S hardener to 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 then surfaces are cleaned with Kiilto Cleaner 303 or Kiilto Cleaner 300. 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. Higher pressing temperature will shorten the pressing time. Take into account adhesive's short pot life. During breaks, the adhesive must be run or wash started approx. 30 sec after the flow has stopped.
