When gluing external joints (e.g. front door panels), the effects of heat (direct exposure to sunlight) can cause stresses in the wood and softening of glued joints. Duroplastic adhesives, such as PUR glue in the dispensing system, art. no. 0892100180 are suitable for this purpose. In conjunction with the tannic acid in the wood, the impact of bare metal may result in blue discolouration, especially with oak, and in red discolouration with beech. In isolated cases, substances contained in wood may result in unpredictable discolouration with various types of wood, e.g. beech, cherry, maple. At a pressing temperature above +50u00b0C, brown discolouration may occur with softwood veneers. Fresh splashes of glue can be removed with water. Older adhesive residues can be softened with nitro thinner or acetone and then rubbed off. Stir the contents thoroughly before application and always close the bottle tightly after use. Protect from frost. The processing time and the setting time are heavily dependent on the working conditions, e.g. the temperatures, moisture and absorption levels of the materials, application quantities and tensions in the material.

Wu00fcrth white glues are not suitable for use in the static range. Specially approved adhesives must be used for this purpose. Wu00fcrth glues may only be used for non-load-bearing applications.
