Loctite 408

Engineered for precision applications where aesthetic appearance and strict vapor control are essential, this very low-viscosity instant adhesive minimizes both blooming (whitening) and strong odors. It delivers rapid bonding for tight-fitting components across a diverse range of materials, including metals, elastomers, and standard plastics. When utilized with a compatible surface primer such as Loctite SF 770, it can also effectively bond difficult low-energy plastics such as polypropylene (PP), polyethylene (PE), and polytetrafluoroethylene (PTFE).

Key Performance Specifications
