Product Details Regulatory Info/SDS
Product Description
3M Hot Melt Adhesives are 100% solids, thermoplastic resins that become fluid when heated and quickly wet the
bonding surface. They cool, harden and reach bond strength in seconds, keeping production flowing by eliminating
clamps, fixturing and drying, and saving time energy and space.
3M Hot Melt 3792 is a thermoplastic adhesive with low to medium viscosity and long open times. It bonds to wide a
variety of substrates such as wood, plain and coated corrugated, sand cores, foams, many plastics, and other
lightweight materials.
Product Features
100% Solids, no VOCs
Easy to use
Long open times allow for ease use on large assemblies and large surfaces
Adhesive sets and obtains strength in seconds
Low Melt (LM) adhesives are designed for low temperature application and heat sensitive substrates
Ideal for woodworking and general industrial applications.

Handling/Application Information
Directions for Use
1. Surface Preparation: Surfaces must be clean, dry and dust free. Wipe with a solvent such as isopropyl alcohol for
plastic substrates to aid in removing oil and dirt.*
*Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer s
precautions and directions for use.
2. Application: 3M Hot Melt Adhesives are designed for application with a 3M Hot Melt Applicators. Read and follow
the precautions and directions for use in the user s manual before operating the applicator. 3M Hot Melt Adhesives are
applied at 350-385 F, except the Low Melt (LM) series which are designed to be applied at 250-275 F. LM series are
adhesives designed for lower temperature application but still yield long-lasting bonds.
Extruded bead sizes can be customized using 3M applicator tips.
3. Coverage: 3M Hot Melt Adhesives yield approximately 430 linear feet per pound of adhesive when extruded as a
1/8 diameter semi-circular bead.
4. Set up time: After the bond is made, 3M Hot Melt Adhesives immediately build strength and no clamping is
necessary. Set will occur faster on cold or metallic substrates.
