3M 3748 TC Epoxy Adhesive Gray

This 3M 3748 TC epoxy adhesive comes as a smooth gray stick designed for hot melt application. It suits assembly, repair and general bonding tasks where a fast-setting structural adhesive is required. The stick format allows controlled dispensing through compatible hot melt equipment. It is not suited for applications that demand a liquid or paste adhesive.

45-second working time

The adhesive begins to harden after 45 seconds, giving a short window to position parts before the bond sets. This working time is the key specification that determines whether the product fits a specific assembly pace. Faster or slower processes will need a different formulation. The fixed 45-second window cannot be adjusted.

5/8 inch diameter by 2 inch length sticks

Each stick measures 5/8 inch in diameter and 2 inches long, providing a defined amount of adhesive per piece. The melting range of 350 to 385 degrees Fahrenheit and a consistent viscosity of 5,000 cps allow steady flow through standard hot melt guns. Very high-volume or continuous-duty applications will consume sticks quickly and may require bulk feed systems.

Questions about this item

How long do I have to position parts once the 3M 3748 stick begins to harden?

The adhesive provides a working time of 45 seconds after it starts to harden, giving you a brief window to align components before the bond sets.

What temperature range must my glue gun reach to melt these 5/8 in diameter sticks?

The sticks require a melting temperature between 350 and 385 degrees Fahrenheit, so your applicator must operate within that range to dispense the adhesive properly.

Will the 2 in length sticks fit my standard 5/8 in hot melt gun?

Yes, the sticks are manufactured with a 5/8 inch diameter and 2 inch length, matching the standard sizing for compatible hot melt applicators.
