Surventis Xmor LD7 was a suspension of an inert white powder in a quick dry solvent used in non destructive testing of forged parts, welds, casts and drop forged parts. This product is no longer available, and has been replaced by Surventis Xmor LD8 or Surventis Xmor LD9, with LD9 leaving a more similar layer of developer after application to that of LD7.
