Loctite 242 is a medium strength, medium viscosity threadlocking compound used for metal thread sizes from 1.5mm to 36mm in diameter. "Blue" or "Medium" is used commonly across all RC applications where metal to metal fixture points are found, and can be removed with ease. 242 specifically requires a clean application surface for best results and bonding properties. Fixture drying times (depending on materials) are up to 20 minutes at maximum. Full cure is 24 hours.
