Main features
- Non-Sag Vertical Application
- 25-Minute Open Working Window
- Galvanized-Steel Peel and Impact
Product Description
LOCTITE AA H8600 is a two-part methacrylate-based structural adhesive system for galvanized steel bonding. Parts A and B mix 2:1 by volume, or 100:50 by weight, forming a blue, medium-viscosity thixotropic material. The non-sag formulation can be applied horizontally or vertically, and 0.13 mm glass beads support bondline control. At 22 deg C, mixed open time is 25 minutes and fixture time on galvanized steel is 55 minutes. Typical lap shear on steel is 23.1 N/mm^2 after 72 hours at 22 deg C. After 5 days at 22 deg C, typical galvanized-steel properties include 6.2 N/mm T-peel and 13.1 kJ/m^2 impact strength.
Key features
- Non-Sag Application: The thixotropic adhesive can be applied horizontally or vertically to required surfaces.
- Open Time and Galvanized-Steel Fixture: Mixed open time is 25 minutes at 22 deg C, with fixture on galvanized steel at 55 minutes.
- Galvanized-Steel Peel and Impact Strength: After 5 days at 22 deg C, typical values on galvanized steel are 6.2 N/mm T-peel and 13.1 kJ/m^2 impact strength.
Applications
Structural bonding of galvanized steel assemblies.
