Propolis Propolis Propolis or bee glue is a resinous mixture that honey bees produce by mixing saliva and beeswax with exudate gathered from tree buds, sap flows, or other botanical sources. It is used as a sealant for unwanted open spaces in the hive. Propolis is used for small gaps (approximately or less), while larger spaces are usually filled with beeswax. Its color varies depending on its botanical source, with dark brown as the most common. Propolis is sticky at and above , while at lower temperatures, it becomes hard and brittle. While foraging, worker bees primarily harvest pollen and nectar,
Fugitive glue some object—product sample or a return envelope—is glued to another, usually paper, object—a mailing envelope or a magazine. They tend to perform best on smooth, non-porous surfaces. In these applications, fugitive glues are not resealable pressure-sensitive adhesives such as are used on pressure-sensitive tapes or post-it notes, although resealable formulations are available. Fugitive glues are usually available in hot melt or latex form, with low VOC emissions. They can be also applied in liquid form. Fugitive glue Fugitive glue, also called credit card glue, E-z-release glue, or (colloquially) booger glue, snot glue, or gooey glue, is a low-tack adhesive that
