Hot melt adhesives (Aron Melt series)
|
|
|
|
|
Hot melt adhesives are thermoplastic adhesives. This adhesive is a solid at normal temperatures. However, it melts with heat and the liquefied form can be applied to an adherend. A bond is formed by cooling solidification. Due to cooling solidification, the bond is formed in a short time and workability is improved.
All adhesives in this series except for the liquid type are a one-liquid, solvent-free type. Polyester, modified olefin, and reactive urethane systems are available. Adhesives can be selected according to adherend and application.
