A Fast-Moving Hot Melt Adhesive
Engineered to deliver excellent results, 3M™ Hot Melt Adhesive 3731 (PDF, 256 Kb) 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.
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.
Some of the recommended applications for this product are the following:
High heat resistance
Hot Melt Adhesives in Brief
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 (PDF, 3 Mb) is that, unlike mechanical fasteners and sealing tapes, they are virtually invisible between surfaces.
Our 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.
A Rapid Solution
For a resilient, durable bond to meet your project needs, we designed 3M™ Hot Melt Adhesive 3731 to not only create a tough bond, but provide this strong adhesion fast. We engineered our hot melt glue to be the adhesive solution you need that meets your demands and excels in performance.
