LOCTITE H5004
Harmonization Code : 3919.10.80 | Other self-adhesive plastic rolls not exceeding 20 cm wide.
Main features
- Fast Room-Temperature Fixture
- Clear High-Peel Structural Bonds
- 1:1 Static-Mix Processing
Product Description
LOCTITE AA H5004 is a two-part acrylic structural adhesive mixed 1:1 by volume for bonding plastics, metals, composites, FRP, stone, and ceramics. The medium-viscosity thixotropic system cures rapidly at room temperature when dispensed through a static mixer. At 25 deg C, gel time is 45 to 70 seconds and a fixture-strength threshold of 0.1 N/mm^2 is reached in 3 minutes or less on degreased, grit-blasted mild steel. The cured adhesive is virtually transparent, with Shore D 59 hardness, a typical Tg of 66 deg C, and high peel and impact strength. It is suited to assemblies where clear bondlines and fast handling are important.
Key features
- Fast Room-Temperature Fixture: Develops 0.1 N/mm^2 fixture strength in 3 minutes or less at 25 deg C on degreased, grit-blasted mild steel.
- Cured Bondline Transparency: The virtually transparent adhesive has Shore D 59 hardness and a typical Tg of 66 deg C.
- High Peel and Impact Strength: The cured acrylic system resists peel, fatigue, and impact loading.
Applications
Structural bonding of plastics, metals, composites, FRP, stone, ceramics, steel, and aluminum.
