Transparent hardening
No visible adhesive joints. Hardened glued joints are viscoplastic.
Due to the different composition of substances contained in wood, in individual cases, unpredictable discolouration can occur, e.g. in beech and cherry. In addition, iron in conjunction with the tannic acid in wood may cause colour changes in oak. The processing time and the setting time are heavily influenced by the working conditions (e.g. temperature). For outdoor applications, the glued section must be protected against the weather and provided with adequate surface protection (permanent protection against moisture ingress). Care must be taken to ensure that the glue is not exposed to direct sunlight outdoors due to its thermoplastic properties. Non-thermoplastic adhesives and PUR glue in a dosing system (0892100180) are suitable for applications with direct exposure to sunlight. Softening of the glue and shrinkage of the wood can lead to joint openings. The viscosity of 1-component D4 glues increases during the storage period. However, the processing parameters do not change as a result. Stirring without adding water makes it free-flowing again. Do not add water to the glue! Remove glue residue escaping at the joint, as this may cause red staining due to reacting with oxygen.
Datasheets(X)
For structural assembly, surface, board-joint and block gluing of soft wood, hard wood and exotic woods. For applications with increased water resistance requirements; indoor areas subject to frequent and long-lasting effects of draining water. Outdoors with adequate surface protection. Examples include bathroom furniture, gluing of interior doors and interior staircases, corner window joints, laboratory equipment. Likewise for gluing laminated profiles and profiles joined lengthwise using finger joints.
Glue is applied to one side thinly and evenly with an application tool, a glue roller, toothed spatula, brush etc. For more information, please refer to the technical data sheet.
