CITGO CITCOOL CONCENTRATES
Date 10/06
DESCRIPTION: These are unique heavy-duty, synthetic coolant concentrates containing lubricity agents, anti-
corrosion additives and other components to satisfy the demands of today鈥檚 high-performance
machining operations. When diluted with water in the proper concentrations, these premium products
function as heavy-duty cutting fluids. Containing no oil, these fluids show distinct advantages over the
more conventional 鈥樷?榮oluble鈥欌?? or 鈥樷?榚mulsifiable鈥欌?? cutting oils commonly used in industry, particularly in the
areas of ease of mixing and cleanup, improved solution stability, freedom from odor and rancidity,
heat transfer, and work face visibility.
Fluids prepared from CITCOOL Concentrates find special uses in a variety of metalworking processes
where the cooling effects of water coupled with a balanced lubricity-corrosion protection additive
package serve to prevent chip buildup and wear at the critical tool-workpiece interface. This extends
tool life and improves worked surface finish.
QUALITIES 鈥? Provide extreme pressure properties for heavy-duty operations.
& BENEFITS: 鈥? Mix easily 鈥? no special procedures required.
鈥? Exhibit transparency for better viewing of the workpiece during processing.
鈥? Eliminate oil mists associated with petroleum oil products.
鈥? Contain no oil; leave no gummy residue.
鈥? Produce stable mixtures in hard water.
鈥? Provide excellent rust and corrosion protection.
鈥? Reject tramp oil readily.
鈥? Exhibit biodegradablility.
鈥? Contain a fungicide to protect against initial fungal growth in service. Monitoring microbial activity
over extended service periods would be advisable to determine need for additional treatment.
鈥? Contain no phenols, nitrites, PCB鈥檚 or heavy metals.
鈥? Resist sludge buildup; economical.
鈥? Display distinctive yellow color for CITCOOL 22 and green color for CITCOOL 33.
鈥? Wash off parts with cool water.
APPLICATIONS: CITCOOL 22 Concentrate is a microemulsion designed for use with aluminum, magnesium and their
alloys, yellow metals, and moderately heavy-duty application on ferrous metals. Appearance will vary
from virtually clear to hazy depending upon the hardness of the water blended with it.
CITCOOL 33 Concentrate is designed primarily for use in machining titanium, ferrous metals and their
alloys and stainless steels. It is non-corrosive to brass and copper and may be used in metalworking
processes with these metals. It is not recommended for use in the machining of aluminum,
magnesium and their alloys due to possible staining.
CAUTION: 1. Plexiglass windows or shields have become 鈥樷?榗razed and cracked鈥欌?? from diluted CITCOOL 33
Concentrate contact. Other window or shield materials such as those made from K-Resin are
not affected.
2. Some paints or coatings on machine surfaces may dissolve or peel after prolonged contact with
CITCOOL 33. Recommended paints: Epoxy. Not recommended: Acrylic and Lacquer-based
coating. Questionable: Oil-resistant Alkyd paints.
3. CITCOOL 33鈥檚 distinctive blue color can fade during storage and use. The change in the color of
CITCOOL 33 does not have any effect on the performance of the product.
