3M 7000000878 Hot Melt Glue Stick 8 in Low Melt Series 3748

Product Description

The 3M 7000000878 is a low-melt hot melt glue stick in the 3M Series 3748 product line, measuring 8 inches in overall length and finished in an off-white color. It is designed for use with compatible hot melt applicator guns and delivers a reliable, fast-setting adhesive bond suited to a wide range of trade and light industrial applications. The UL 94 V-2 flame rating confirms the adhesive meets a recognized flammability standard. With an 11-pound package size, this item is suited to production-volume or multi-job purchasing. Installation is performed by technicians and tradespeople working across automotive, electrical, flooring, packaging, and upholstery sectors.

The Series 3748 low-melt formulation is appropriate for heat-sensitive substrates where standard high-melt sticks would cause warping or surface damage. Typical applications include automotive interior bonding, electrical component securing, flooring and subfloor adhesion, general-purpose assembly, packaging closures, and upholstery attachment. The stick bonds to plastic substrates and is sized to fit hot melt applicators compatible with the Series 3748 platform. This makes it a practical choice for shop or field techs who need a consistent, repeatable adhesive in a standard stick form factor.

Installation Notes

Load sticks into a compatible low-melt hot melt applicator gun only — do not use in standard high-temperature applicators not rated for this series. Allow the applicator to reach proper operating temperature before dispensing to ensure consistent bead quality. Keep the applicator tip clear of combustible materials during use, and follow the applicator manufacturer's guidelines for purging and storage. Work in a well-ventilated area when bonding in confined spaces.
