  • Lowest viscosity fluid that remains pumpable down to 35°F / 2°C
  • Low toxicity
  • Compatible with a broad range of materials including most metals, plastics and composites
  • Good Surface wetting due to low surface tension and solvent properties.
  • Slow Drying at ambient temperatures

Contains no glycerin which can interfere with subsequent penetrant inspection.

Environment and operator friendly – no formaldehydes, nitrates, nitrites or glycol ethers.

Minimal residue

Removal: Wipe with wet or dry paper or cloth rag or water wash.
