Sun Chemical Rycoline Metering Roller Cleaner 91438041

Sun Chemical Rycoline Metering Roller Cleaner (MRC), part number 91438041, is a fast-drying, non-water-miscible solvent wash specifically formulated for cleaning rubber metering and pan rollers in the dampening systems of lithographic offset presses. Metering rollers are critical to maintaining consistent ink-water balance: when they become glazed, ink-contaminated, or coated with grease and other press debris, dampening performance deteriorates — leading to scumming, tinting, and inconsistent water feed throughout the press run.

Rycoline MRC is engineered to penetrate and dissolve ink, glaze, grease, and other contaminants from rubber roller surfaces, restoring a clean, resilient, and water-receptive surface. Unlike general-purpose press washes that can swell or degrade dampening rubber if used repeatedly, MRC is specifically formulated for the rubber compounds used in water system metering and pan rollers, making it the preferred maintenance cleaner for the dampening train.

The non-water-miscible chemistry ensures that MRC lifts and removes contamination effectively without emulsifying into the dampening solution — keeping the water system clean and performing optimally. Fast drying reduces downtime between cleaning and press startup.

Features:
Fast-drying formula
Deep cleaning — removes ink, glaze, grease, and contaminants
Restores water-receptive roller surface
