Hot-melts are a type of thermoplastic adhesive that are generally 100% solid and are brought to a liquid state by applying heat. Hot melt pillows are melted using a hot melt tank/hopper and are then applied to a substrate in its liquid state. As the hot melt cools to room temperature, it solidifies, and a strong bond is created.
Stuart Francis, managing director of Chemique Adhesives comments: “For over 30 years we have made progressive steps towards eliminating hazardous solvents from the workplace. Our hot-melts have been designed for both automatic and manual systems, so whether you are automatically applying the adhesive in a bead or a swirl pattern or indeed hand beading or spraying, then we have a grade to suit.”
The company says that hot-melt adhesives are a much more stable option than many solvented adhesives and are easy to store, as they do not require any special conditions other than the avoidance of extreme temperatures.
