Tru TempTM low-temperature black oxide process allows users to produce high quality black finishes without salt bloom. Salt bloom is the white powder that often appears in recessed areas and holes on hot oxide finished parts. It occurs because ordinary hot oxide baths are viscous and difficult to rinse. By remaining on the finished part, the hot oxide bath residue grows into fine particles of salt. Tru Temp uses solutions that are milder and cooler. They rinse freely, leaving a residue-free finish. The bath operates at 190F, well below the boiling and spattering temperature range.
