PRODUCT OVERVIEW
What is FC120?
FC120 is a neutral, biodegradable liquid finishing compound formulated for vibratory finishing, rumblers, and barrel polishers. It provides a balanced combination of cleaning, polishing, and brightening for most metals processed in mass finishing systems.
Why it's Useful
Many finishing operations require a single, versatile compound that can handle multiple metal types and finishing steps without frequent changes or flushing. FC120 simplifies the process while improving surface condition and consistency.

TECHNICAL BENEFITS & FEATURES
Wide Material Compatibility
FC120 is suitable for most industrial metals — from stainless steel to aluminium and titanium — so you can standardise your finishing fluid without frequent swaps.
Balanced Cleaning & Polishing
Its chemistry helps degrease parts and prevent media clogging, which enhances surface quality and process efficiency.
Promotes Bright, Consistent Finishes
FC120 supports both surface smoothing and polishing, making it ideal for operations that combine deburring with finishing or burnishing.
Backed by Rösler Consumables Expertise
FC120 uses compound chemistry from the Rösler liquid compound range — engineered to keep process water, parts, and media clean across diverse metals and finishing goals. Rösler’s comprehensive consumables portfolio ensures that FC120 delivers balanced cleaning, polishing and corrosion protection performance across most industrial metals.
USAGE INSTRUCTIONS
Dilution & Mixing
-
Dilute at 1–2% with water.
-
Stir thoroughly to ensure an even solution before use.
In-Machine Use
-
Load parts and media into your vibratory or tumbler machine.
-
Add the diluted FC120 solution to your water reservoir.
-
Run the finishing cycle while monitoring foam and finishing results.
Process Tips
-
Avoid excessive compound use — too much can create froth that cushions media action and reduces finishing efficiency.
-
Clean or replace media regularly to maintain optimal compound performance.
MATERIAL COMPATIBILITY
