Package Sizes: 45 ml, 490 ml cartridges
Shelf Life: 24 months

Product Description

3M™ Scotch-Weld™ Low Odor Acrylic Adhesive DP8825NS is a two-part, toughened structural acrylic adhesive designed for high-performance bonding with low odor and non-flammable formulation. It provides excellent shear, peel, and impact resistance, bonding well to metals, plastics, and composites, including slightly oily surfaces. The adhesive features a controlled bond line thickness due to incorporated glass beads and offers fast strength build-up, making it ideal for industrial and manufacturing applications.

Key Features

  • Toughened formula – excellent impact and vibration resistance
  • Low odor and non-flammable – improved workplace safety and comfort
  • Excellent shear and peel strength – strong, durable bonds
  • 10:1 mix ratio – precise control over bond line thickness
  • Fast strength build-up – structural strength in less than an hour
  • Bonds a variety of materials – metals, plastics, composites, and oily surfaces

Recommended Applications

  • Automotive and transportation – bonding of panels and structural components
  • Aerospace and defense – lightweight and durable composite bonding
  • Electronics and electrical assembly – vibration-resistant bonding
  • Industrial manufacturing – securing structural parts and enclosures
  • Signage and displays – strong, weather-resistant adhesion
