Fluorescent and Visible Penetrant Products

Approved to MIL-I-25135 & AMS-2644

Water Washable Fluorescent Penetrants

Level 1/2

  • HM-1 - For relatively non-critical work.

  • HM-2D - Recommended for magnesium and aluminum casting with difficult surfaces.
  • HM-220 - Free rinsing; use on difficult surfaces. No petroleum distillates.
  • WB-100 - Water-based; environmentally friendly. Also shipped as concentrate; user adds water.

Level 2

  • HM-3A - Versatile, general purpose material; used extensively on aluminum and magnesium castings; competitively priced.
  • HM-406 - Widely used in aerospace on magnesium, aluminum and titanium castings and extrusions. More sensitive than HM-3A. Also in spray cans.
  • HM-412 - Similar to HM-406, only more sensitive.
  • HM-440 - Free rinsing. Contains no petroleum distillates.
  • HM-602 - Resists over-washing. Contains no petroleum distillates.
  • WB-200 - Water-based; environmentally friendly. Also shipped as concentrate; user adds water.

Level 3

  • HM-430 - High sensitivity; formulated for rough surfaces.
  • HM-604 - Widely used. Competitively priced. No petroleum distillates. Resists over-washing.
  • HM-607 - Similar to HM-604 except slightly more sensitive.

Level 4

  • HM-704 - Ultra-high sensitivity. Used on smooth surfaces. No petroleum distillates.

Nonwater-Washable Fluorescent Penetrants

Level 1

  • RC-29 - Competitively priced.

Level 2

  • RC-50 - Widely used.

Level 3

  • RC-65 - Also in spray cans.

Level 4

  • RC-77 - Also in spray cans.
  • RC-88 - Ultra-high sensitivity; increases visibility of microscopic flaw indications.

Emulsifiers for Fluorescent Penetrants - Methods B & D

  • ER-85 - Method B lipophilic, oil-based, used in post-emulsification processes.
  • ER-83A - Method D hydrophilic, detergent-based, "non-aggressive," used after plain-water pre-rinse, recommended for use with RC-77 on highly critical rotating parts.

Cleaners and Removers for Fluorescent Penetrants - Method C

  • DR-60 - Clear, non-chlorinated solvent for pre-cleaning and penetrant wipe-off. Also in spray cans.
  • DR-62 - Similar to DR-60; evaporates more readily. Also in spray cans.
  • LA-1 - Alkali-based, hot tank pre-cleaner. Replaces solvent-based pre-cleaners.

Developers for Fluorescent Penetrants

  • D-90G - Dry powder, "form a," excellent surface cling.
  • D-100 - Nonaqueous, "form d," alcohol suspension, spray application. Also available in spray cans.
  • D-106 - Nonaqueous, "form d," similar to D-100, evaporates more readily; spray application. Also available in spray cans.
  • D-113G.1 - Water soluble powder, "form b," normally used with nonwater-washable penetrants.
  • D-110A.1 - Water suspendable powder, "form c."

Visible Pentrant Products

Approved to MIL-I-25135 & AMS-2644

Visible Penetrants

  • DP-51 - Water-washable, remove with water or solvent. Also in spray cans.
  • DP-54 - Water-washable, contains no petroleum distillates, more acceptable to sewage treatment facilities. Remove with water or solvent.
  • KO-17 - Specially formulated and approved for high temperature applications, such as welds. Use with Hi-Temp K-019 Cleaner and with D-350 or D-100 Developers. Also in spray cans.
  • By-Lux - Dual response: indications are red under normal light; orange under black light. Also in spray cans.

Removers/Cleaners

  • DR-60 - Clear non-chlorinated solvent for pre-cleaning and penetrant wipe-off. Also in spray cans.
  • DR-62 - Similar to DR-60; evaporates more readily. Also in spray cans.
  • KO-19 - Foam cleaner especially formulated for use at high temperatures. Use with other Hi-Temp products. Also, use when wide, shallow cracks are suspected. Also in spray cans.

Emulsifiers for Visible Penetrants

  • ER-85 - Method B, lipophilic, oil-based. Use with nonwater-washable penetrants.
  • ER-83A - Method D, hydrophilic, detergent-based, "non-aggressive." Use after plain water pre-rinse to emulsify nonwater-washable penetrants.

Developers for Visible Penetrants

  • D-100 - Nonaqueous, "form d," alcohol suspension, spray application. Also available in spray cans.
  • D-106 - Nonaqueous, "form d," similar to D-100, evaporates more readily; spray application. Also available in spray cans.
