3M Scotch-Weld Low Odor Acrylic Adhesive DP8805NS Green

Overview

3M Scotch-Weld Low Odor Acrylic Adhesive DP8805NS Green is a high-performance, two-part acrylic adhesive that offers excellent shear, peel and impact performance. Its toughened formula gives improved adhesion to many plastics and metals, including slightly oily surfaces and most powder coats, and it builds structural strength within minutes. Low odor and non-flammability make it easier to use in a manufacturing process than typical acrylics. According to the technical data sheet (September 2024) it has a 10:1 mix ratio by volume and weight (off-white base, blue accelerator; mixed and cured colour blue-green), a work life of 3-5 minutes, open time of about 5 minutes, set time of 6-8 minutes, structural strength (1,000 psi / 6.9 MPa) in 8-10 minutes and full cure in 24 hours at 23°C. Typical 7-day overlap shear strengths (light abrasion and solvent clean) are 24.1 MPa on aluminium, 22.8 MPa on stainless steel, 12.4 MPa on PVC, 8.3 MPa on ABS, 6.9 MPa on acrylic (PMMA) and 5.9 MPa on polycarbonate; modulus is 965 MPa and tensile strain at break 8.5%. The adhesive contains glass beads (0.010 inch diameter) to control bond line thickness, and heat speeds the cure. The data sheet refers to UL File QOQW2.MH17478 and the Sign Components Manual (SAM) File E464624 for certification in electrical equipment. Supplied as a 490 mL Duo-Pak; best used within 24 months of manufacture when stored at 16-27°C.
