D350 High Temperature Developer 9 X 16oz Case

D350 High Temperature Developer 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.

At lower temperatures, D-350 dries more slowly. Also, the particles are more adhering at lower temperatures and require greater effort to remove upon completion of the inspection process. Removing D-350 requires wiping with water-dampened toweling
