There are four types of water based adhesives: latex cements, animal or protein glues, resin cements and vegetable glues. Each category has individual characteristics. They are generally solvent free, which means they can be used in areas that are not particularly well ventilated. The most popular form of water based adhesive is wood glue. Although water based glues have been used for decades, their popularity is declining due to the increasing popularity of hot melt glues.
What are Hot Melt Adhesives?
Hot melt adhesives are solvent-free glues made from thermoplastics. They are mixed and applied when molten. They are melted at temperatures between 120° and 180°C. This type of adhesive is superior to water-based adhesives because they provide better hold and they also have superior manufacturing flexibility. Hot melt glues can be used in a wide variety of applications such as:
- Product assembly
- Pressure sensitive tapes
Hot glues are most commonly supplied in solid sticks which can be purchased in a rage of diameters to suit the specific application. They are designed to be melted as they pass through a heated glue gun. The glue is then applied from the nozzle. When the glue is applied it is hot and tacky. It solidifies within a few seconds to one minute. As well as the glue gun application, hot melt adhesives can also be applied using spraying or dipping. These adhesives are usually clear, translucent or amber, though pigmented hot glues are also available.
