Scotch-Weld Low Odor Acrylic Adhesives DP8805NS Green DP8810NS Green Technical Data Sheet February 2014 Product Description 3M Scotch-Weld Low Odor Acrylic Adhesives are high performance, two-part acrylic adhesives with lower odor than most acrylic adhesives. These toughened products offer excellent shear, peel, and impact performance. They provide improved adhesion to many plastics and metals, including those with slightly oily surfaces. These durable products feature an exceptionally fast rate of strength build, providing structural strength in minutes. UL Certification QOQW2.MH17478 Features Toughened Work life of approximately 4 or 10 minutes Excellent shear strength Structural strength in about 9 or 21 minutes High peel and impact strength Increased cure speed with applied heat 10:1 mix ratio Contain glass beads (0.010 diameter) to control bond line thickness Note: Unless otherwise indicated, all properties measured at 72F (22C). Note: The following technical information and data should be considered representative or typical Typical Uncured only and should not be used for specification purposes.

These adhesives also have relatively low adhesion to low surface energy plastics (such as polypropylene, polyethylene, TPO, and PTFE). Applications involving any of these materials should be carefully evaluated by the end user for suitability. 8 Mechanical Properties 3M Scotch-Weld Low Odor Acrylic Adhesive Property DP8805NS Green DP8810NS Green Tensile modules (psi) 140,000 125,000 Tensile strength (psi) 1,800 1,650 Tensile strain at break (%) 8.5 6.5 8.
