Product Description

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.


Key Features

  • 100% Solids Composition: Contains no VOCs, making it environmentally friendly.
  • Fast Setting: Provides quick “hot tack” adhesion, achieving strength in seconds.
  • Excellent Packaging Adhesive: Specifically designed for corrugated, chipboard, and wood bonding.
  • Low to Medium Viscosity: Ensures good flowability and ease of application.
  • Works with 3M™ Hot Melt Applicators: Ensures efficient and consistent dispensing.

Recommended Applications

  • Corrugated Carton Sealing & Packaging
  • Woodworking and Furniture Assembly
  • Bonding Beadboard, Chipboard, and Lightweight Materials
  • Carton Repacking and Box Sealing
