SumTech® AQ-320 is a Barium complex ISO 320 lubricating grease for use in wet environments. The special Barium complex thickener is resistant to steam and mild alkaline and acidic solutions preventing SumTech® AQ-320 from becoming washed out of the lubricating area. The nature of the special thickener system gives SumTech® AQ-320 a very tacky nature which is similar to the specific gravity of water, providing an unprecedented level of protection against water washout and corrosion. Premium anti-oxidants provide excellent thermal stability and a blend of corrosion inhibitors extend the excellent anti-corrosion nature inherent of the thickener. SumTech® AQ-320 is the grease of choice for marine, pulp and paper, and steel mill industries where exposure to water and aggressive media cannot be avoided. SumTech® AQ-320 is also suitable for use in sealing water valves, labyrinth seals, and rotary steam unions.
