Fish Glue

Name:
Fish Glue
Detailed information:
An adhesive derived from the skins of commercial fish (chiefly cod). A ton of skins yields about 50 gal liquid glue. Bond strength on wood is approximately 2500 psi, pH approximately 6.5–7.2. Compatible with animal glues, some dextrins, some polyvinyl acetate emulsions, and rubber latex. Chief applications are in gummed tape, cartons, blueprint paper, and letterpress printing plates. Fish glue can be made light sensitive by adding ammonium bichromate and water insoluble by UV radiation, hence its usefulness in the photoengraving process.See Adhesive.
