What is natural protein glue?
Animal Glue or Protein Glue, an adhesive commonly used for Case making is also called Gelatin Glue, Jelly glue or Glutin. It is made of connective tissue and bones and hides of animals. It is manufactured using animal protein which is obtained by breaking, milling the bones and cooking or boiling the raw-materials.

Collagen peptides are not exactly the same as gelatin. Both are proteins made of amino acids, but the amino chains of collagen peptides have been cut into smaller pieces through a specific hydrolysis process. Collagen peptides do not have the gelling functionality of gelatin and are soluble in cold water.

What are the advantages of casein glue and the limitations of casein glue?
There's no chemical bond at play here; just a huge amount of tiny forces. Think of it like millions of tiny magnets pulling the surfaces together. Because these forces are very weak, the two surfaces must be very close together to stick. The closer the surfaces get, the stronger the force of attraction.
