With the Rotorsprays 97115, Loctite® Products can be applied to the interior cylindrical surfaces of workpieces.The Rotorsprays are operated in combination with Dispensing Valves 97134 or 97135/97136. The simultaneous control of these units requires the use of Loctite® Controller 97123 or 97103 with a Solenoid Valve module 97204. The special design of the drive assembly and rotor housing ensures that the rotospray is completely sealed to prevent contamination with adhesive. Low to medium viscosity anaerobic adhesives can be applied with the Rotorsprays.
