Description of DIESTONE SRM

DIESTONE SRM is the former PF-SRM manufactured by PT Technologies Europe.
DIESTONE SRM is a heavy duty, residue free higher flash point solvent based cleaner and degreaser for surface cleaning of gross soils, sealant and adhesive residues, fabrication soils and marking inks during Aerospace MRO and OEM parts cleaning operations. Effectively removes semi-cured polysulphide sealants, RTV materials, Skydrol marks, stickers, tape and combustion residues. It is also an effective cleaning solvent in preparing and cleaning tooling of composite structures.

  • Contains a masking agent for odour sensitive operators
  • 100% volatile solvent – leaves no residue after complete evaporation
  • Substitute for low flash point solvents such as MEK, IPA & Acetone
  • Bond breaker to penetrate beneath the adhesive, break the bond and lift from surface
  • Controlled evaporation rate
  • Reduces solvent consumption, costs & VOC emissions when moving from fast evaporating solvent cleaners
  • Suitable for use on metal, solvent resistant organic coatings and composites/composite tooling
  • Low content of sulphur chlorides, nitrogen, peroxides and acids
  • Non-corrosive on metals such as copper, aluminium, magnesium, stainless steel etc.
  • Suitable for cold cleaning solvent immersion or swab/wipe
  • Available in liquid and pre-saturated on low lint wipes such as SOCOSAT 15233 – a cloth compliantwith AMS 3819C qualification requirements
  • Pre-saturated wipe system eliminates the hazardous storage, transport and logistical issues of loose flammable liquids


DIESTONE SRM is a solvent based cleaning system designed to provide effective surface cleaning of sealant residues, fabrication soils and markings on metallic and composite structures.

Directions for use

Apply a thin film of DIESTONE SRM using liquid or a pre-saturated wipe
Allow a few minutes for surface action to dislodge contaminants
Wipe off with the same pre-saturated wipe or with a clean, dry low lint cloth (recommended)
Allow surface to dry and apply coatings / sealing etc.
Dispose of all wipes in an appropriate bin
