RLN-27 DERUSTING CHEMICAL RLN-27 is a specific type of derusting chemical used for removing rust and corrosion from metal surfaces. It's formulated to dissolve rust and leave the metal surface clean and ready for further treatment or coating. Here's some general information about RLN-27 and how it might work: 1. Chemical Composition: RLN-27 could contain specific acids or chemicals that are effective at breaking down iron oxide (rust). Common ingredients might include phosphoric acid, citric acid, oxalic acid, or other rust-inhibiting agents. 2. Mode of Action: The chemicals in RLN-27 work by reacting with the rust on the metal surface, converting the iron oxide into a water-soluble compound that can be easily rinsed away. This process typically involves applying the derusting chemical directly to the rusted area and allowing it to work for a certain period before rinsing off.
