3M™ Hot Melt Adhesive 3762 is a 100% solids, fast-setting thermoplastic adhesive designed for corrugated packaging, beadboard, chipboard, wood, and other lightweight materials. It features good “hot tack” and low to medium viscosity, making it ideal for fast and reliable bonding in high-speed production lines. The adhesive forms instant bonds upon cooling, eliminating the need for clamping or extended drying times.
