DESCRIPTION
Windoline 444® High Perform-ance
Synthetic Grease is a synthetic complex grease with outstanding properties including a wide temper- ature range estimated at -45 to
260°C and a high load-carrying
capacity. It combines the most impor-
tant properties of silicone grease (wide temperature range) and solid lubricant-containing PTFE greases (high load-carrying capacity) in an ester-based grease.
