TRUEGARD SYNCOOL 428 is a heavy duty water based cutting fluid concentrate. When diluted properly, TRUEGARD SYNCOOL 428 is suitable for most machining operations on ferrous and nonferrous metals. Outstanding lubricity combines with the superior cooling power of a chemical coolant.

TRUEGARD SYNCOOL 428 utilizes a unique combination of extreme pressure additives to prevent welding at the tool point. This immediately reduces heat generation and improve surface finish. This chemical lubricity permits the chips to slide easily over the tool at the chip-tool interface. This reduces friction and thus heat generation.

TRUEGARD SYNCOOL 428 also reduces surface tension, allowing the coolant to thoroughly wet all machining surfaces. This increases the rate of heat removal, allowing the tool and work to remain cooler. Better tool life is readily achieved.

TRUEGARD SYNCOOL 428 contains the latest development in fungicides to ensure long coolant life and productivity. TRUEGARD SYNCOOL 428 is inherently low foaming. This precludes the use of silicone defoamers which can cause fish-eyeing on steel surfaces. Other defoamers which leave a heavy cream on the coolant surface are also unnecessary. TRUEGARD SYNCOOL 428 is a technologically advanced product for the modern machine shop.

Frequently asked questions

Find answers to common questions about our products and services

  • Syncool 428 is a water-based cutting fluid concentrate, not a neat (oil-based) cutting oil. It must be diluted with water before use, which combines the lubrication characteristics of a cutting fluid with the superior heat-removal capacity of a chemical coolant.

  • When diluted properly, Syncool 428 is suitable for most machining operations on both ferrous (iron-based) and nonferrous metals, making it a versatile choice for mixed-metal machine shops.

  • The refractometer factor of 3.6 is a multiplier applied to your refractometer reading to determine the actual concentration of Syncool 428 in your sump - multiply your reading by 3.6 to get the approximate percentage concentration. Regularly checking this value helps you maintain the correct mix ratio and ensures consistent performance over time.

  • Silicone-based defoamers can cause fish-eyeing defects on steel surfaces, which affects surface finish quality. Because Syncool 428 is inherently low foaming, it eliminates the need for silicone defoamers entirely, protecting the integrity of finished workpiece surfaces.

  • The EP additives are designed to prevent metal-to-metal welding at the tool-chip interface, which directly reduces heat generation and friction. This results in improved surface finish on the workpiece and extended tool life, particularly during demanding cutting operations.

  • The built-in fungicide inhibits microbial growth in the coolant sump, which is a common cause of coolant degradation, foul odors, and reduced effectiveness. Longer coolant life means fewer sump changeouts and more consistent machining productivity over time.
