3M 7100008738 Hot Melt Adhesive Stick 5/8 X 8 Inch Tan

Product Description

The 3M 7100008738 is a tan hot melt adhesive stick formulated for general purpose bonding in trade and industrial applications. Known under the Scotch-Weld 3738 Q designation, this stick measures 5/8 inch in diameter and 8 inches in length, sized for standard hot melt dispensing equipment. It delivers a high flow rate and an extended open time, giving installers and technicians adequate working range during assembly. The adhesive bonds well to wood substrates and select plastics, making it a practical choice for a range of fabrication, repair, and assembly tasks across HVAC, woodworking, and general trade environments.

This adhesive stick is suited for residential and light commercial applications where fast, reliable bonds are needed on wood and compatible plastic surfaces. It is dispensed through hot melt glue guns and applicators designed for 5/8 inch diameter sticks. The long bonding range is particularly useful in assembly line or multi-point bonding scenarios where working time is critical. Technicians in HVAC duct fabrication, insulation work, and general maintenance will find this a convenient and consistent bonding solution.

Compatibility

Designed for use in hot melt applicators that accept 5/8 inch diameter adhesive sticks. Bonds to wood and select plastics as specified by the manufacturer.

Installation Notes

Allow the hot melt applicator to reach full operating temperature before dispensing to ensure consistent flow and bond strength. Apply adhesive to a clean, dry surface free of dust, oil, and loose material. Follow the applicator manufacturer guidelines for safe handling, as the adhesive and applicator tip reach high temperatures during use. Allow the bond to cool and set fully before applying load stress to the joint.
