In the presence of a catalyst, the molecular weight will increase, creating a polymer. Organic glues are made by first washing animal hides, bones, and other tissues to remove dirt and debris. Any final traces of lime are removed with the help of acetic acid or hydrochloric acid. Blood albumen glue. He is deeply fascinated by Robotics and Artificial Intelligence.

Understanding how glue is made and the differences between glue types can help you decide on the best material for your applications. Other organic glue ingredients include casein, blood albumin, fish swim bladders and vegetable starch. The molecules of this acrylic resin react on contact with the hydroxyl ions found in water. This process is time-consuming, with a vat of glue taking 12-24 hours to mix in some cases.A more efficient option is a high shear disperser, which typically utilizes a high shear dispersion blade.
