Master Chemical Trim C320 High-lubricity Synthetic
TRIM® C320 is a high lubricity, low foam, synthetic coolant that approaches the “down-the-hole” machining performance of premium soluble oils. This product is exceptionally good on aluminum. Even with its very high performance, C320 meets or exceeds most stringent environmental standards.
• Excellent extreme pressure (EP) lubricity to do many drilling, tapping, reaming, and form-grinding operations without any chlorine or sulfur-based EP additives
• A very versatile product which works well in mixed metal situations including aluminum, steel alloy, cast iron, and copper alloy
• Provides good corrosion inhibition on all common ferrous and nonferrous alloys
• Keeps grinding wheels clean and sharp for higher “G ratios”, better surface integrity, and faster stock removal
• Contains no DEA, nitrides, phenolic compounds, “formaldehyde releasers”, or chlorine
• Operators like C320’s very low odor, low foam, low mist, and light yellow working solution
• Keeps your machines clean while leaving a soft fluid film that protects the bare metal parts
• Machines are easily washed off with coolant working solution to minimize the buildup of residues and chips
• Exceptional sump life, great resistance to fungus and bacteria, and good tramp oil rejection
• C320 is a super product for aluminum wheel machining
• C320 has increased tendency to foam as the fluid temperature falls below 80°F (27°C).
• Concentration should be kept at 7.5% or higher for operations at lower SFPM, soft or “gummy” material, or
operations where finish is a factor.
• C320 is not recommended in machine tools that rely on splash lubrication from the coolant; e.g., older screw machines or transfer machines.
• C320 is not recommended on magnesium or zirconium without special precautions.
• This product may “wash out” dirt and residues when a machine is first charged. Machines should be thoroughly precleaned with Whamex™ before charging.
• Concentration should be at least 5% on cast iron and 4% on steel to help prevent in-process corrosion.
• Concentrations of 7.5%-10% usually give the best tool life, finish, and sump life; however, the best concentration for your operation should be determined by on-site testing.
