Magnobond 6380 A/B

Description

Magnobond 6380 is a toughened epoxy adhesive/shim system having good properties over a wide range of temperatures.

Special Features

  1. Excellent bonding is achieved to a variety of substrates without use of metallic fillers.
  2. Magnobond 6380 will set to handling strength in 6 hours at room temperature and develop full properties after 3 days. A heat cure can be used if faster production is needed.
  3. Magnobond 6380 contains glass spacers to provide a bond line thickness of 5 to 7 thousandths.
  4. Shelf life is 12 months when stored at 75°F or lower.
  5. Magnobond 6380 A/B is QPL listed to Boeing/Sikorsky Specification 2000-777-0160-02, DASH-001A, Rockwell MBO-120-037 Type II, Class I and Sikorsky SS8622-007A Rev. 5.
