They are derived from collagen, a protein constituent of skins and connective tissues and are principally of cattle origin. The manufacturing process consists essentially of the following steps: washing the raw materials, soaking in a lime solution (which weakens the chemical bonds), the extraction of the gelatinous material, gelling and finally drying. The resulting glue can be in powder, granules or pearls and has an indefinite shelf life if kept in a cool dry place. for the details of thetechnical parameter and method of application,please contact our salesman,we will provide service to you as soon as possible.
