3M™ Hot Melt Adhesive 3731

3M Hot Melt Adhesive 3731 is a 100% solids, high heat resistant thermoplastic adhesive that liquefies to bonds to a variety of substrates, including polyethylene, polypropylene and other plastics.

Engineered to deliver excellent results, 3M™ Hot Melt Adhesive 3731 provides high heat resistance up to 265ºF/129ºC without lifting or deformation. This hot melt adhesive bonds well to a variety of substrates and is an ideal adhesive for bonding polyolefin based plastics, including polyethylene and polypropylene. In addition, 3M™ Hot Melt Adhesive 3731 is fast setting, with an open bead time of 30 seconds, for applications requiring quick bond times. Designed to provide good peel strength, 3M™ Hot Melt Adhesive 3731 creates a resilient bond that is long-lasting, offering confidence and peace of mind for a wide range of applications. For use with the 3M™ Hot Melt Applicator EC or 3M™ Hot Melt Applicator TC.

Recommended Applications: Ideal for bonding polyolefin based plastics and for applications requiring quick bond times.

Applied with 3M™ Adhesive Applicators, hot melt adhesives extrude as liquefied thermoplastic to fill gaps and wet entire bonding surfaces before setting. As a result, 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.
