What are these new adhesives?

3M™ Scotch-Weld™ Low Odor Structural Acrylic Adhesive 8805NS and 8810NS are a non-sag, toughened, two-part acrylic adhesives with 10:1 mix ratio. They have a 5 and 10 minute work life respectively, and handling strength in approximately 7-10 minutes.  Inspired by fast-setting composite material in the dental industry, 3M has introduced Scotch-Weld DP8805NS and DP8810NS low-odour acrylic adhesives for sign making, metalworking and other manufacturing activities.

What makes this new adhesive unique?

Compared to conventional high-odour acrylics, the new non-flammable, low-odour acrylic formulation helps ease health and safety concerns in today’s sign manufacturing facilities and reaches structural strength almost twice as fast.  3M has also focused on improving impact resistance, shear  and peel performance and adhesion to a wide range of plastics and metals.

8805Features:

  • 5 minute work life for 8805
  • 10 minute work life for 8810
  • Available in 45 mil cartridges and 490 mil tubes
  • Low odour
  • 10 : 1 mixing ratio
  • Fast rate of strength build-up
  • Blue/Green in colour
  • UL Certification QOQW2.MH17478

Important to Note: Environmental aging tests have shown that these adhesives may accelerate the corrosion of certain metals such as bare steel, copper, brass, and bronze. This leads to low bond strength values and early bond failure.These adhesives also have relatively low adhesion to low surface energy plastics (polypropylene, polyethylene, TPO, and PTFE). Applications involving any of these materials should be carefully evaluated by the end user for suitability.

Storage Details: These new adhesives offer an 18-month shelf life, with no need for refrigeration.
