Hampdon industrial stock the Sherwin range of non-destructive testing (NDT) products. Sherwin are industry grade products and conform with or exceed ASME and AS standards. Great for engine builders, home fabricators and professional engineering companies.

Developer consists of refined white particles suspended in isopropanol alcohol to give enhanced sensitivity for locating tight, incipient flaws; by solvent and capillary action, it pulls flaw-entrapped penetrant to part surfaces for display against a white background.
