PRODUCT DATA SHEET KEY FEATURES AND BENEFITS • Synthetic lubricant base • Biodegradable • Superior heat dissipation • Excellent lubricity • Internal resistance to microbial attack MACHINERY COOLANT APPLICATION AREAS • Tapping • Boring DESCRIPTION Chesterton® 380 Machinery Coolant is a high-performance, low maintenance, synthetic metal working fluid. It provides superior lubricity and cooling for a variety of machining operations. It is recommended for alloy steels, cast irons and exotic metals. Machinery Coolant will provide protection against bacterial growth and is very tolerant to hard water. It is usable for a broad range of machining operations ranging from slow speed applications to high speed turning. It is ideal for high precision, high quality and custom machining operations. The excellent lubricity and coolant properties of 380 reduce heat in the chip formation process, which extends tool life when compared to conventional soluble oils and semi-synthetics. • Grinding • Milling Before adding 380 to any reservoir, remove old coolant, chips and other resideual matter from the system. Thoroughly rinse the reservoir with water until the pH is within .1 of make up water. Mix the concentrated 380 into water. Do not add water to the concentrate. Pour the diluted coolant into a clean reservoir. Do not mix 380 with any other coolant. Diluations in excess of 4% are not recommended since the corrosion protection provided by 380 and it's internal resistance to bacterial attack will be reduced. Coolant Maintenance: 380 is designed for minimum maintenance. For maximum life, its is recommended that the concetration be checked regularly using a refractometer to insure that the mix ration is correct. Tank side additives are availabel to control foam and bacterial contamination. • Threading • Machining • Sawing • Turning TYPICAL PHYSICAL PROPERTIES Flash Point (ASTM D 93) Specific Gravity Clear, Colorless Liquid Boiling Point Hard Water Stability Fire Point (ASTM D 92) Freezing Point Freeze Thaw Stability Before using this product, please refer to Safety Data Sheet (SDS).
