D-106 developer consists of refined white particles suspended in acetone 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.

KO-17 along with KO-19 Cleaner/Remover and D-350 Developer comprise Sherwin Incorporated's HI-Temp Penetrant System, which works at temperatures above which ordinary penetrants are ineffective.

KO-19 along with KO-17 Penetrant and D-350 Developer comprise Sherwin Inc's Hi-Temp Penetrant System, which works at temperatures above which ordinary penetrants are ineffective. It is used in the penetrant process to remove excess KO-17 Hi-Temp Penetrant from part surfaces or for cleaning an insoection surface prior to applying KO-17 Penetrant. KO-19 meets low halogen and low sulfur requirements. It is a nonchlorinated material and non-miscible in water. It is relatively volatile and...

D-350 along with KO-17 Penetrant and KO-19 Remover comprise Sherwin Inc's Hi-Temp Penetrant System, which works at temperatures above which ordinary penetrants are ineffective. D-350 developer consists of refined white particles suspended in isopropyl 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. It is not recommended for use at temperatures...

DP-51 is a red colored dye penetrant liquid used to locate cracks, laps, pores, lack of bonding, and similar surface flaws in any insoluble, nonporous substance including both ferrous and nonferrous metals, ceramics, glass and many plastics. Referred to as the "visible dye penetrant" method or "color contrast" method inspection.

DR-62 Cleaner-Remover is used in the penetrant process to remove excess, nonwater-washable penetrants from part surfaces, e.g., Sherwin DP-40 Dye Penetrant (visible red) and Sherwin RC-65 and RC-77 Fluorescent Penetrants. It is a manual "wipe on" and "wipe off" material and, consequently, recommended for small areas. DR-62 may also be used for generally cleaning oily, dirty surfaces. DR-60 is especially suitable for cleaning prior to the application of inspection penetrants. DR-62 is widely...
