Adhesive (Gum) - What is a gum adhesive?
Definition of ADHESIVE GUM:
This term refers to a type of reactive adhesive that creates an adhesive bond via a chemical reaction caused by the presence of water. These adhesives are also known as water sensitive adhesives because they must be exposed to water to become tacky (sticky); there are two main types of gum adhesive, which are made with either a dry gum (which has a dull matt finish) or a conventional gum (which has a shiny gloss finish). These adhesives are best suited to paper-based products and surfaces (although some are also suitable for use on cardboard and glass), and are commonly used in the production of envelopes and stamps that are sealed or applied by moistening the adhesive layer (sometimes known as "lick and stick").Go Back to Glossary
