22. Metal-Free / Ashless Additive Technology
Traditionally ZINC, a heavy
metal has been used in anti-
wear hydraulic fluid
formulations as ZnDTP
– Inexpensive lubricant additive,
however not the best solution
in terms of various
environmental aspects
ASHLESS Technology
– Reduces &/or eliminates
substances that have
significant aquatic toxicity
– Easily substitutes ZnDTP
– Provides better performance
