casein glue

The casein glue, it was said, cracked when exposed to extreme heat and/or monsoon conditions.

In 1876, the first US patent (number 183,024) was issued to the Ross brothers for the production of casein glue.

Casein glue, therefore, is sold as a white dry powder consisting of dried whey, caustic soda or something similar, and lime.

Casein glue is also used in transformer manufacturing (specifically transformer board) due to its oil permeability.

Casein glue was used to make strong and robust joints in early aviation, but fell out of favor due to its susceptibility to attack by bacteria.

The following decades of the next century witnessed the manufacture of casein glues in German and Swiss factories.

The outcome was then baptized with a water-soluble resin casein glue (bond 484 tacky), poured from a plant-watering can with a shower-sprinkle spout."

Casein glues were very widely used during the war in aircraft and one day somebody discovered that the tensile strength of specimens of wet casein is one-fifth of that of dry casein.

In fact, in bygone days, a reaction such as you describe was a common and a popular means to produce an early form of glue - now supplanted by good old Elmer's carpenter glue which is very different in composition and far superior to casein glue.

Its C of A expired again in July 1974 because its wing had been damaged by damp (casein glue failure) during the previous winter, when it had been left out in its closed trailer at St. Mary's Farm, Clifton, near Deddington, Oxon.
