PRESSURE SENSITIVE ADHESIVES are applied to a surface and permitted to dry. That surface will then adhere to most other materials on contact with pressure. Bonds may be temporary or permanent. These adhesives are usually made from natural or synthetic rubber. SELF-SEAL OR COHESIVE (COLD SEAL) LATEX ADHESIVES - an adhesive that will adhere only to itself. Bond strength is variable and may be permanent or resealable. May be used as a protective coating that will not transfer to the material being coated. HEAT SEAL ADHESIVES are waterborne resin heat seal adhesives. Heat seals are applied to one surface and dried. Adhesive is then activited for bonding by applying heat. Temperatures required vary from 175°to 300°F depending on adhesive. FUGITIVE ADHESIVES form a temporary bond between two materials. The two materials may then be separated without damaging either surface. Made from natural rubber latex, it has no tack, dries clear, and is non-staining.
