Jowapur® 681.10 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 manufacturing bonded load-bearing timber structures.

Characteristics / Directions for Use:

Jowapur® 681.10 was tested by the Materials Testing Institute (MPA, Otto-Graf Institut) of the University of Stuttgart, Germany in accordance with EN 15425:2017. It has been established that the adhesive can be used for the manufacture of bonded load-bearing timber structures according to EN 14080:2013, EN 15497:2014, and EN 16351:2015. In addition, the MPA Stuttgart has also determined the performance characteristics of the adhesive following EN 15416-4/5. Based on the results from the tests, Jowapur® 681.10 has been classified as follows: Adhesive Type: EN 15425 – I – 70 – GP – 0.3 – w for general purposes in the manufacture of bonded load-bearing timber structures made of spruce, fir, or pine wood. for bonding fingerjointed assemblies in lamellas of load-bearing timber structures made of spruce, fir, pine, Douglas fir, European larch, and pressure impregnated pine. The manufacture of load-bearing timber structures is subject to the specifications in the applicable national and/or European regulations for the manufacture of the corresponding timber structures (e.g. EN 14080, EN 15497, EN 16351, diverse ETA, etc.). Beyond that, the information indicated on this this Technical Data Sheet is to be observed. Appearance: beige to yellowish Density [g/cm³]: 1.15 (Jowat test method) 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.


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 product properties finally agreed.
