The curing of hot melt adhesives is a relatively simple form and is a physical change. Hot melt adhesive is a solvent-free pure solid adhesive product, which needs to be heated and melted to make it into a liquid form.
As early as 6,000 years ago, humans used clay and other mud to build earth-rock houses and other structures. Traces of adhesive can be seen on ancient Egyptian masks, coffins and other funeral objects and furniture, carvings in ancient Greece Thebes.
The Industrial Production of adhesives began in the 17th century. In 1690, the Netherlands first created a factory to produce natural polymer adhesives. In 1700 Britain established a factory mainly producing bone glue.
Adhesives have a variety of classification methods, generally classified according to chemical composition, form, process, use, etc.
Solvent Based Adhesive refers to an adhesive made of natural rubber, synthetic rubber, synthetic resin, and other macromolecular compounds dissolved in an organic solvent and adding an appropriate amount of modifier. The volatilization cures it of the solvent.
Hot melt adhesives are polymer-based and apply to a substrate in a molten state. These types of glues are commonly applied with an industrial glue gun, which works by a trigger or finger pressure. These types of glues are used in a number of settings, including bookbinding and carton-making,
If your hot melt adhesive is smoking, there are several things you can try to fix it. One of the most common causes of hot melt smoke is improper temperature. Too little heat or too much can result in stringing and smoke. Aside from being uncomfortable, the burnt glue can also contribute to the disc
