Engineered to deliver excellent results, 3M™ Hot Melt Adhesive 3731 is a high heat resistant adhesive that offers long term durability by withstanding elevated temperatures without lifting or deformation. This hot melt adhesive also bonds well to a variety of substrates and is an excellent candidates for bonding low surface energy (LSE) substrates, including polyethylene and polypropylene. In addition, 3M™ Hot Melt Adhesive 3731 is fast setting, with an open bead time of 30 seconds, presenting strong results and tough bonds within a short period of time. Designed to provide good peel strength, our Hot Melt Adhesive 3731 creates a resilient bond that is long lasting, offering confidence and peace of mind for a wide range of applications.
 
Recommended Applications

3M™ Hot Melt Adhesive 3731 can be utilized in many industries, including automotive, construction , furniture, signage, consumer goods, specialty vehicle, transportation, military, retail, electronics, woodworking and packaging.
 

Hot melts are 100% solids thermoplastic resins. These adhesives are engineered to re melt after bonding if exposed to high enough temperatures. The advantages of hot melt adhesives is that, unlike mechanical fasteners and sealing tapes, they are virtually invisible between surfaces.
 
Hot melt adhesives liquefy when heated, quickly fill gaps and wet the bonding surface. When they are applied to a surface, they cool, harden and reach their bond strength within seconds. Due to their quick work life, you can move assemblies immediately upon application which eliminates the need for clamps, fixturing or additional drying time and energy.
