PRODUCT OVERVIEW Primary Applications Technical Benefits & Features Usage Instructions Material Compatibility Why Choose FC120 Which Liquid Finishing Compound is Right for You? Recommended Products 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. FC120 is ideal for most vibratory processes — learn more in our guide to vibratory finishing PRIMARY APPLICATIONS Designed to work with plastic, ceramic, or porcelain media. Best Suited For Mixed metal workloads — ideal when processing a variety of steel, aluminium, brass, copper, titanium or precious metals. General cleaning & polishing — effective for deburring, radiusing, smoothing and bright surface finishes. Degreasing components prior to coating or assembly. Ball polishing / burnishing with non-abrasive media (e.g., porcelain or plastic). Machine Compatibility Vibratory finishers Tumbler / rumbler machines Barrel polishing systems ��Explore Vibratory Finishing machines & systems at Moleroda 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 Material Recommended Use Stainless Steel ✔️ Versatile cleaning & polishing Aluminium ✔️ Brightened, cleaned surface Copper & Brass ✔️ Effective finish & degrease Titanium & Precious Metals ✔️ Universal compatibility Steel / Iron ✔️ General finishing (not corrosion-focused) Zinc & Pewter ✔️ Good cleaning & smooth finish WHY CHOOSE FC120 One Compound for Many Jobs FC120 is ideal when you need a single finishing compound across multiple materials and operations — from deburring and smoothing to polishing and final surface brightening. Efficient & Cost-Effective By standardising to a universal compound, you reduce inventory complexity and the need to flush machines between batches. Developed within Rösler’s global consumables programme, FC120 benefits from decades of surface finishing research and environmentally considerate compound design. Its formulation supports efficient debris removal and media activity with reduced environmental impact — reflecting Rösler’s leadership in modern mass finishing chemistry.
