In case of non-absorbent substrates and wood with moisture content below 8 %, the adhesive film or the materials to be bonded are to be fogged. Please take care during pressing to prevent the press from gluing shut. Coat the press with a suitable Jowat® release agent for PU adhesives. We recommend using release paper. Our Application Technology Department and our Application Specialists will provide technical data to assist you in your choice of an appropriate product for your requirements. Please observe the information in the section “Remarks”. General bonding requirements The properties (e.g. surface tension, plasticiser content…) and the conditioning of the substrates, as well as the processing conditions (e.g. ambient temperature, humidity…) will influence the processes of joining and bonding. Customer tests under consideration of everyday production conditions are therefore absolutely necessary to define stable process parameters and to ensure that the product is fit for purpose. For best bonding results, the materials to be bonded should be free of dust, oil, and grease, and be dry. Ideally, the minimum temperature should be at 18 °C. Avoid draught.


Before curing the prepolymer can be cleaned with a solvent-soaked rag for instance using Jowat® Thinner 401.30 or with Jowat® PUR Cleaner 402.38. After curing only mechanical removal (emery paper.
