I use Castrol Syntilo 9828 coolant to machine carbon composites. It\u2019s certified for Boeing and Bombardier composite fiber parts.
Pros: certified for composite fiber
Part number: SYNTILO 9828
I find a solution with 30% coolant SF series castrol and 70% Distilled water with 5% Mocool(motul). This mixture has made a more faster cooling and slow overheating run.
Pros: faster cooling, slow overheating
Cons: still not enough
I stopped having to wear gloves when we stopped using blaser coolant. That shit gave me blister covered rashy skin that was unbearable for 2 years. All went away as soon as we switched to a cheaper Castrol coolant. Works about the same too.
Pros: cheaper, works about the same
Cons: blister covered rashy skin
At the time I filled the system with 60/40 mix of Castrol antifreeze and distilled water. Been treating me nice since 2017.
Pros: reliable performance
Vehicle:
Jeep Grand Cherokee
Mb50 Castrol is excellent coolant
