Reducer is a large number of equipment used in industrial enterprises. Once the oil leaks, it will not only cause economic losses. If the oil leaks, it will cause the reducer to lose oil and cut off the oil, which will increase the wear of the gear meshing surface, and then seize or peel off, resulting in equipment accident. Moreover, the oil spill pollutes the surrounding environment severely and has a corrosive effect on the foundation, which not only destroys civilized production but also wastes a lot of lubricating oil that can be recovered and regenerated. Fanle reducer sealant series products use neutral silicone sealant. The biggest advantage of this material is high bonding strength, no corrosion to the substrate, good comprehensive mechanical properties, corrosion resistance, easy molding, and processing.
