Pre applied adhesives are pre-applied on the threaded parts before they are used. They are of two types reactive and non-reactive. Reactives are adhesives used for achieving highest possible locking properties and an extreme sealing effect. When the threaded parts coated with precote are assembled the microcapsules are ruptured by pressure and/or shearing loads. The liquid content mixes and cures with the binder system. Non- reactive are used in the field of sealing screw joints and clamping.
