MG Chemicals 408C Rubber Renue, Rejuvenate and Restore Belts, 125mL 408C Rubber Renue restores old rubber parts that have hardened and lost their tackiness and flexibility. It causes the rubber to swell, allowing dirt to come out of its pores. When the solvent dries, the rubber returns to its form and remains tacky, allowing rollers and platens to retain their grip. Applications and Uses: 408C Rubber Renue restores the tackiness of platens and rollers, helps to remove dirt, ink, and sticky residues, and may also restore the flexibility of belts, conveyors, and seals. It works by causing the rubber cells of belts, platens and rollers to swell, allowing dirt particles and contaminants to be wiped away easily.
