RubberMAX Green Beast™ is a medium viscosity thixotropic high strength, flexible retaining compound. Our proprietary monomer teamed with RubberMAX , cross links durability, and flexibility into every application. Green Beast™ bonds bushings, bearings, and gears to shafts, creating a plastic shim which seals the joint, prevents corrosion, and ultimately protects the shaft. It is also an excellent choice for high strength thread locking on medium size fasteners, where extreme durability is required.
