LOCTITE AA H3500
Harmonization Code : 3919.10.80 | Other self-adhesive plastic rolls not exceeding 20 cm wide.
Main features
- Simple 1:1 Structural Mixing
- Fast Room-Temperature Fixture
- High-Shear Metal Bonding
Product Description
LOCTITE AA H3500 is a two-part methacrylate structural acrylic adhesive system with 1:1 mixing for high-strength bonding of compatible metals and plastics. Parts A and B form a light yellow mixture that cures at room temperature. At 21.1 deg C, the mixed adhesive has a 7 to 9 minute open time and an 18 to 20 minute fixture time. Typical cured properties include 22.1 N/mm^2 lap shear on ground steel, 13.8 N/mm^2 on aluminum, and 33.3 N/mm T-peel on aluminum-to-aluminum joints after 24 hours at 22 deg C. Equal-ratio mixing and fast handling-strength development suit structural assembly.
Key features
- Equal-Ratio Mixing: Parts A and B use a 1:1 ratio by both weight and volume for straightforward two-part dispensing.
- Fast Room-Temperature Fixture: Fixture time is 18 to 20 minutes at 21.1 deg C after a 7 to 9 minute open time.
- Steel and Aluminum Bond Strength: Typical lap shear reaches 22.1 N/mm^2 on ground steel and 13.8 N/mm^2 on aluminum after 24 hours at 22 deg C.
Applications
Structural bonding of compatible metals and plastics.
