Description:

SPIRIT 620 S represents the most up-to-date technology in the development of a bio-stable EP fortified semi-synthetic metalworking fluid. It accomplishes this without formaldehyde releasing biocides, secondary amines, or amines of questionable safety. It is non-irritating to operators, as its basicity is obtained from materials used in the cosmetics industry. It is multi-metal compatible, has high lubricity for both aluminum and steel cutting, yet still has excellent ferrous rust protection with a breakpoint of 2% on cast iron chips. The surfactants used in SPIRIT 620 S are non-ionic, allowing the product to form a stable micro emulsion with water of all qualities, from 0 to 700 ppm, yet very waste treatable by acid-alum methods. 

Applications:

SPIRIT 620 S is recommended for light to heavy duty ferrous applications and light to moderate duty aluminum applications. Operations include: milling, turning, drilling, boring, O.D. and I.D. grinding operations including centerless and surface grinding. 

Advantages:

• Easily forms a translucent micro-emulsion in all types of water

• Long coolant sump life

• Bio-stable without formaldehyde release

• Contains no nitrites, phenols or di-ethanolamine

• Improved tool life

• No sulfur

• Has an effective rust inhibitor

• Cleaner machines

• Excellent work piece visibility

• Greater operator acceptance

• Rapid cooling

• Will not stain aluminum

• Excellent for recycling

• Low foaming in soft water

• Splits out tramp oil quickly
