PERPURA 38 is a brilliantly clear, almost colorless, low-viscous liquid aqueous sodium silicate solution with reduced heavy metal contents. It is particularly suitable for industrial applications requiring high transparency and clarity in final formulations. PERPURA 38 offers significant benefits for industrial solutions due to its trace heavy metal content and biocide-free properties. Its purity and clarity allows for consistent performance in industrial processes. PERPURA 38 is stable for 12 months when handled properly and is suitable for use in applications with stringent requirements.
