3M 7000121341 Hot Melt Adhesive Clear 5/8 X 2 Inch

Product Description

The 3M 7000121341 is a low-melt, long-bonding-range hot melt adhesive designed for use with compatible hot melt applicator equipment. Supplied in a clear stick format measuring 5/8 inch in diameter and 2 inches in length, this adhesive is formulated to apply at lower temperatures than standard hot melts, which reduces the risk of heat damage to sensitive substrates. Weighing 1.07 pounds per unit, it is well suited for production and assembly applications where a fast-setting, reliable bond is required on lightweight or delicate materials. Technicians and assemblers in manufacturing, HVAC fabrication, and light assembly environments regularly specify this adhesive for its controlled open time and clean handling.

This adhesive is intended for bonding heat-sensitive substrates including styrene foam, wood, select plastics, corrugated board, and other lightweight materials. Its low-melt formulation makes it appropriate where conventional high-temperature adhesives would warp, melt, or degrade the workpiece. Typical applications include insulation board assembly, packaging fabrication, decorative panel bonding, and light fixture or ductwork liner attachment. It is dispensed using the 3M Scotch-Weld Hot Melt Applicator LT, which is sold separately.

Key Features

• Low-melt formulation reduces heat stress on sensitive substrates such as styrene foam and thin plastics
• Long bonding range provides extended open time for alignment and positioning before set
• Clear adhesive color blends discreetly on finished assemblies
• Stick format at 5/8 inch diameter and 2 inches in length for use with compatible applicator guns
• Bonds wood, corrugated board, select plastics, foam, and lightweight materials

Compatibility

Designed for use with the 3M Scotch-Weld Hot Melt Applicator LT. Compatible with heat-sensitive substrates including styrene foam, wood, select plastics, corrugated board, and lightweight materials.

Installation Notes

Allow the applicator to reach full operating temperature before dispensing to ensure consistent flow and bond quality. Power down and unplug the applicator when changing adhesive sticks or clearing jams. Do not use this low-melt adhesive in high-temperature applicators rated above the product operating range, as this can degrade adhesive performance and create a safety hazard. Follow the applicator manufacturer guidelines and applicable workplace safety standards when operating hot melt equipment.
