Recipe: Casein Wood Glue
Recipe from: Hans Hadert, Kaseinleim und Kaseinfarbenbindemittel, 2. Aufl. Berlin 1937, p. 52.
Processing
Step 1: Stir 100 g of casein powder (#63200) into 200 g water (#65000) and let it soak.
Step 2: Dissolve 11 g of sodium hydroxide (#64050) in 50 g water, then add this to the casein whilst stirring.
Step 3: Stir 20 g of slaked lime (#31800) into the casein glue. This recipe makes about 250 ml of casein glue.
Note
The glue is low viscous, but strong, even in thin layers. The milky and yellowish-white glue solution, dries transparent and yellow. This glue cannot be stored and must be prepared and used the same day. It stays workable for max. 7 hours, then the glue gets stringy. Casein glue dries relatively water resistant. A higher lime content would improve the water resistance but would cause the glue to gel faster and would shorten the working time.
We assume no liability for the processing instructions described above. In any case, we recommend the production and evaluation of sample surfaces.
