Calcium Greases
Calcium greases are a basic grease which provide high-anti rust capacity and high water resitance. They have a mineral oil base and are used as general lubricants for metallic surfaces, frames & car bodies.
Calcium Greases
Calcium greases are some of the oldest greases manufactured.
They are made by chemically reacting hydrated lime with tallow fatty acid in the presence of mineral oil. After saponification is complete, more mineral oil is added, along with water as a structure modifier, to obtain the desired consistency.
They are smooth and buttery in texture, have excellent water resistance, a fair mechanical stability, are easy to apply and have melting points just under the boiling point of water.
Their lower temperature characteristics are governed by the mineral oil that is used as a dilution.
Their maximum temperature is usually limited to about 150°F, while they may survive 200°F for short periods of time.
Calcium grease is used in areas where temperatures are not encountered that would destroy the structure. They are found in the automotive and farm industries primarily, along with the steel industry where normal temperatures are involved.
Usually, this involves the fortification of the grease with an extreme-pressure additive or the addition of graphite as a filler. Other uses include chassis lube, mine car grease, fifth wheel grease, track roll grease and water pump grease.
