Propolis while also collecting water and tree resin necessary for the production of propolis. The chemical composition and nature of propolis depend on environmental conditions and harvested resources. For centuries, beekeepers assumed that bees sealed the beehive with propolis to protect the colony from the elements, such as rain and cold winter drafts. However, 20th century research revealed that bees not only survive, but also thrive, with increased ventilation during the winter months throughout most temperate regions of the world. Propolis properties may include: The composition of propolis varies from hive to hive, from district to district, and from season to
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
