3M 7000121331 Hot Melt Adhesive Stick 0.5x10 Inches 25 Lb

Product Description

The 3M 7000121331 is a general purpose hot melt adhesive stick designed for fast-setting bonding across a wide range of lightweight materials. Formulated as a 100% solids thermoplastic adhesive, it requires no solvents and sets quickly to reduce assembly time. Each stick measures 0.5 inches in diameter by 10 inches in length and is light tan in color. This adhesive is applied using a compatible hot melt glue gun and is well suited for production environments and job-site applications where consistent, reliable bonding is required. HVAC insulation contractors and general assembly technicians are the primary users.

This adhesive is commonly used to bond fiberglass insulation, felt, shoddy, paper, and similar lightweight materials to metal substrates and other surfaces. It is well suited for residential and light commercial HVAC applications where duct liner, duct board, and insulation materials must be adhered quickly and durably. The fast set time makes it practical for production-line and field installation scenarios where repositioning time is limited.
