Solstice® PF-HP

Aerospace Cleaner For Cleanliness Verification & Vapor Degreasing

Solstice PF-HP
SKU: 10639750, 10640064

Honeywell’s Solstice® PF-HP (High Performance) is an ultra-clean (very low non-volatile residue content), highly-effective, nonflammable aerospace solvent with a favorable toxicity profile and low environmental impact.

In 2015, NASA announced it had tested Solstice Performance Fluid (PF), stating it is a “preferred replacement for cleaning and non-volatile residue (NVR) verification sampling of NASA propulsion oxygen systems hardware, ground support equipment (GSE), and associated test systems.”

  • ASTM G72/G72 m-15 Approved for LOX Components
  • A safer, effective choice for precision parts cleaning. specifically for parts that will be used in oxygen service
  • Less than 2ppm NVR
  • Cleans mineral oils, heavy grease, silicone oils, vacuum oils, silicone grease, refrigerant oils, cutting oils, fluorinated oils, and Krytox
