Product Description
3M Scotch-Weld Acrylic Adhesive DP805 is a toughened, non-sag two-part acrylic adhesive for structural bonding of metals, ceramics, wood, and most plastics. Base and accelerator mix 1:1 by volume or weight. At 23 deg C, typical work life is 3 to 4 minutes in a static mixing nozzle, and set time is 7 to 10 minutes to reach 0.3 MPa overlap shear. Applied open time is approximately 3 minutes. Typical full cure takes 8 to 24 hours at 23 deg C, using a criterion of at least 80% of ultimate aluminum-to-aluminum overlap shear. Typical cured Shore D hardness is 79 at 23 deg C.
Key features
- 3 to 4-minute work life: This typical maximum static-mixer residence interval applies at 23 deg C; applied open time is approximately 3 minutes.
- Non-sag component rheology: Typical viscosities at 23 deg C are 75,000 cP for the base and 150,000 cP for the accelerator by Brookfield RVF, spindle 7 at 20 rpm.
- Shore D 79 cured hardness: This typical cured-material value is measured at 23 deg C by ASTM D2240.
Applications
HVAC and appliance metalworking; specialty vehicles; sign manufacturing; bonding plastics, composites, and powder coats to metal.
