Primary Chemistry:
Alkoxy silicone
LOCTITE® SI 5611 is a premium-quality, two-part adhesive formulation containing an alkoxy silicone base. It should be mixed in a 10:1 ratio by volume to form a grey liquid formulation with low viscosity and neutral curing. As a non-corrosive sealing liquid it easily bonds with various substrates allowing it to be used in the bonding of lighting, solar, switches, and electronic connectors. LOCTITE® SI 5611 exhibits excellent self-leveling properties becoming tack free in 6 minutes.
