LOCTITE® SF 7400 is a fast-drying inking fluid that offers consistent performance under various conditions in industrial marking applications, withstanding temperatures ranging from ─35°C to 145°C. Known for its dark red color, LOCTITE® SF 7400 ensures a clear visual indication on components that is easy to spot against various surfaces to designate that they have been tested or set for tamper proofing or marking. It adheres easily to various substrates, drying quickly by solvent evaporation to leave an organic polymer-pigmented film. It is especially suitable for high-paced work environments due to its ability to set in less than 5 minutes and fully cure in 6 hours, optimizing workflow and minimizing downtime.
