Hygric Properties of Gelatine-Based Adhesives. Studies about wood adhesives have been carried out for several years in the Institute for Building Materials ETH Zürich. Several investigations about adhesives that have been published are [2, 3, 4, 5, 6]. In this work, three types of gelatine-based adhesives (animal glues) which are hide, bone and fish glue were investigated. As a comparator, one type of synthetic adhesive one-component moisture-curing polyurethane adhesive (1C-PUR) was investigated simultaneously. The focuses of this work are on moisture transport and sorption properties of the adhesives. Therefore, two experimental tests diffusion test and sorption test were performed. In the results from diffusion test, it is found that animal glues have a very less vapor resistance against moisture. Which means that water can easily diffuse through the animal glues. The results of sorption test shows a higher moisture content inside animal glues compare to synthetic glue. It recorded for a very wet condition (20°C/95% RH) the moisture content reach up to approximately 60% for animal glues and only 3% for synthetic glue.
