3M™ Hot Melt Adhesive 3731 is engineered to provide excellent results with high heat resistance up to 265ºF/129ºC without lifting or deformation. This hot melt adhesive is ideal for bonding polyolefin based plastics, including polyethylene and polypropylene. It bonds well to a variety of substrates and is fast setting, with an open bead time of 30 seconds, making it perfect for applications requiring quick bond times. The adhesive is designed to provide good peel strength, creating a resilient bond that is long-lasting, offering confidence and peace of mind for a wide range of applications. It is recommended for use with the 3M™ Hot Melt Applicator EC or 3M™ Hot Melt Applicator TC.
Recommended Applications- Ideal for bonding polyolefin based plastics
- For applications requiring quick bond times
Hot melt adhesives are applied with 3M Adhesive Applicators and extrude as liquefied thermoplastic to fill gaps and wet entire bonding surfaces before setting. They often exceed 100 psi shear strength for quick, convenient strength. Hot melt adhesives are used for bonding a wide variety of materials ranging from wood to corrugated cardboard, heat-sensitive foam, plastics, and metals. Unlike mechanical fasteners or sealing tapes, hot melt adhesives are virtually invisible between mating surfaces. These 100% solids thermoplastic resins are available in a variety of strengths, temperatures, and pen time/bonding ranges to meet your specific application demands.
