What is Loctite 4210?
Loctite 4210 is a black, low viscosity, rubber toughened instant adhesive engineered specifically for high temperature environments. In addition to the impact and peel resistance typical of a rubber toughened cyanoacrylate, it retains bond strength after prolonged exposure to heat and humidity, making it well suited to components that will see continuous service temperatures. It is suitable for bonding metals, plastics and rubbers.
