Features & Benefits
Formaldehyde Free
No formaldehyde releaser biocide — improved operator health profile and simplified workplace compliance across South African manufacturing and engineering operations.
Multi-Application Performance
Suitable across turning, milling, drilling, tapping, threading, reaming, sawing and grinding — a single coolant covering the full range of machining operations in a general engineering workshop.
Excellent Cooling Properties
Semi-synthetic technology delivers outstanding heat removal — maintaining workpiece dimensional accuracy and extending tool life in high-speed and high-feed machining operations.
Good Corrosion Protection
Reliable corrosion protection of workpieces and machine surfaces when used at recommended concentration — reducing component rejection rates and machine maintenance costs.
Good Fines Handling
Good metallic fines handling during grinding operations — maintaining coolant cleanliness and extending sump life between changes in grinding and general machining environments.
Good Tramp Oil Rejection
Resists tramp oil incorporation — maintaining coolant performance and extending sump life by preventing the bacterial growth and coolant deterioration associated with tramp oil contamination.
