Clarix P21 belongs to Ostec-Integra's Clarix (Гидронол) family of cleaning fluids for electronics manufacturing, a range that covers PCB, stencil, and equipment cleaning products used across SMT and wave-soldering lines. As with its P-series siblings, it is expected to be a ready-to-use or concentrate-diluted aqueous cleaning fluid intended for flux, residue, or equipment cleaning duties within a soldering or assembly process. No manufacturer datasheet for this specific code was available on ostec-materials.ru at the time of writing, so composition, technical parameters, application details, and packaging cannot yet be confirmed. This entry should be updated with verified data from Ostec-Integra's technical documentation before it is published live.
