Loctite LB 8801 is a non-curing silicone paste that seals, lubricates, protects, waterproofs, and electrically insulates metal, rubber, and plastic parts. Use is as a moisture barrier for electrical contacts, a rubber and plastic lubricant, a mold release agent, and a packing lubricant for shafts and valve stems. It is useful as a stopcock lubricant, plug or ball valve lubricant, valve stem packing lubricant, and protector for electrical contacts. It also protects electrical connections against water infiltration, acring, and keeps moisture from forming a conductive film on electric mounts and insulators. Loctite LB 8801 has excellent fluid resistance to water based fluids, alcohols, mineral oils and vegetable oils.
