Hot Melt Adhesive

Technical Data

July, 2016

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 3776LM, 3792LM, 3738 and 3792 are thermoplastic adhesives with

low to medium viscosity and long open times. They bond to wide variety of substrates

such as wood, plain and coated corrugated, sand cores, foams, many plastics, and other

lightweight materials.

3M™ Hot Melt Adhesive 3792

Multi-purpose adhesive with medium viscosity.

Bonds dissimilar substrates such as wood to

plastic, fabric to metal.

Low temperature dispensing version of 3792.

Excellent for coated papers, plastics and other

heat sensitive substrates.

General purpose bonder with low temperature

dispensing.

Low viscosity and long open time for high flow

rates, thin bonds, and repositionability.
