Jowapur® 686.20 is a joint-filling, fibre-reinforced one-component adhesive based on polyurethane. It cures with wood moisture and/or ambient humidity to create a water-insoluble resin, and is used for bonding fingerjointed assemblies in load-bearing timber structures

Characteristics / Directions for Use:

Jowapur® 686.20 was tested by the Materials Testing Institute (MPA, Otto-Graf Institut) of the University of Stuttgart, Germany, and classified according to EN 15425:2017 as follows: Adhesive Type: EN 15425 – I – 70 – FJ – 0.1 – w It has been established that Jowapur® 686.20 can be used for bonding fingerjointed assemblies in load-bearing timber structures according to EN 14080:2013, EN 15497:2014, and EN 16351:2015 made of spruce, fir, pine, Douglas fir, Siberian larch, or European larch wood. In addition, the MPA Stuttgart has also determined the performance characteristics of the adhesive following EN 15416-4/5. Jowapur® 686.20 has received the general national technical approval of the building authorities by the Deutsches Institut für Bautechnik (DIBt) with certificate number Z-9.1-622 for the manufacture of fingerjointed assemblies in softwood. 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.


The product should remain stored in properly closed original containers, dry and cool (15 – 25 °C). At no time must the adhesive be exposed to temperatures below +5 °C. For best-before date, please see container label. After the elapse of the best-before date, it is essential that you again verify that the product is fit for your intended application.


Information about packaging types and units is available upon request.


For further information concerning safety, handling, transport and disposal, please refer to the Safety Data Sheet. The information on this data sheet is based on test results from our laboratories as well as on reported experience gained in the field by our customers. It can, however, not cover all parameters for each specific application and is therefore not binding upon Jowat, nor should it be relied upon in lieu of your own required testing. The information given in this leaflet does not represent a performance guarantee. Unless otherwise agreed with our customers, the values stated in the section “Specification” shall be regarded as the finally agreed upon product properties. No liability may be derived from the information contained herein nor from the information provided by our free technical advisory service.
