The gums are made of lignocellulose which is secreted in the form of resin from resin ducts of plant. It is an adhesive substance which is used in artificial adhesion of different substances. It is capable of causing a large viscosity in solution. Fevicol is different from gums as it is a artificial substance. Fevicol is a synthetic glue. These adhesives are a mixture of ingredients (typically polymers) dissolved in a solvent. As the solvent evaporates, the adhesive hardens. Depending on the chemical composition of the adhesive, they will adhere to different materials to greater or lesser degrees. These adhesives are typically weak and are used for household applications.
