3M 7100320278 Scotch-weld Epoxy Adhesive DP125 Gray 48.5 Ml

Product Description

The 3M 7100320278 Scotch-Weld DP125 is a two-part, 1:1 mix epoxy adhesive formulated for structural bonding in applications where thermal expansion and dissimilar substrate compatibility are critical concerns. Supplied in a 48.5 mL Duo-Pak cartridge for metered, controlled dispensing, it offers approximately 25 minutes of open working time and reaches handling strength in about 150 minutes. Full cure occurs in approximately 7 days at 72 degrees F. Rated UL 94 HB, it delivers flexible, durable joints with low odor, making it well-suited for assembly work in enclosed or occupied spaces. Installers and assemblers in industrial, commercial, and light-trade settings reach for DP125 when bonding mixed-material assemblies.

DP125 is designed for structural bonding on metal, ceramics, stone, and many plastics including ABS. Typical applications include appliance manufacturing, transportation component assembly, signage fabrication, and general industrial assembly where joints must tolerate vibration, impact, and differential thermal movement between bonded materials. The Duo-Pak cartridge format ensures a consistent 1:1 mix ratio with each dispense, reducing waste and mix error on the job. This listing covers a case of 12 cartridges.

Compatibility

Formulated for bonding metal, ceramics, stone, and plastics including ABS; suitable for appliance, transportation, signage, and general industrial assembly applications requiring flexible, impact-resistant structural joints.

Installation Notes

Surface preparation is critical for epoxy adhesive performance — substrates should be clean, dry, and free of oil, grease, and loose particles before application. Use the recommended 3M mixing nozzle for the Duo-Pak cartridge format to ensure proper 1:1 ratio dispensing; discard the first short bead before applying to the joint. Allow adequate fixture time before applying load to the bond. Follow applicable workplace safety guidelines for adhesive handling and ventilation even with low-odor formulations.
