Unopened at +10–25 °C in a container (1000 l) for 6 months, in smaller containers 12 months. After long storing, stir before use.
The surfaces to be bonded must be clean and dry.Remove oxides by sanding, and grease and other dirt with Kiilto Cleaner 303. Stir Kestopur PL 250/20 resin first and then add the hardener and stir until the mixture is evenly coloured. Apply the adhesive on one or both sides of the materials to be bonded. Remove fresh adhesive stains with a dry cloth and clean the surfaces with Kiilto Cleaner 302, 300, acetone or other suitable solvent. Hardened adhesive can only be removed by mechanical means. We recommend gluing at room temperature. Gluing can be carried out at below room temperature (+5–10 °C), but the hardening process will be slower and application may be affected.
