3M 7100005566 Scotch-weld 3748-PG Hot Melt Adhesive 22 Lb

Product Description

The 3M 7100005566 is the Scotch-Weld Hot Melt Adhesive 3748-PG, a general-purpose thermoplastic adhesive supplied in stick form measuring 1 inch in diameter by 3 inches in length. Designed for use with compatible hot melt applicator guns, this adhesive melts and flows when heated, then sets quickly as it cools to form a durable bond. It is non-corrosive to copper, making it suitable for applications where copper substrates or components are present. The 3748-PG formulation offers good thermal and electrical insulating properties, making it a practical choice for trade professionals who need a fast-setting, general-purpose bonding solution across a variety of substrates.

This adhesive is used in industrial, commercial, and residential applications where a fast-setting hot melt bond is required. It bonds to a wide range of substrates including polyolefins, which are materials that many adhesives fail to grip reliably. Typical applications include assembly work, component mounting, wire tacking, and general fabrication tasks performed by electricians, HVAC technicians, and maintenance professionals. The product is sold in a 22-pound minimum quantity lot, packaged per individual stick unit, making it suitable for shops or service operations with high-volume adhesive needs.

Installation Notes

This adhesive is applied using a compatible hot melt applicator gun — verify the applicator is rated for the required melt temperature before use. Allow the applicator to reach full operating temperature before dispensing to ensure proper flow and bond strength. Keep the adhesive and applicator away from flammable materials during use. Handle hot melt adhesive with care to avoid contact burns, and allow bonds to cool fully before applying load to the joint.
