Designed for drying applications

SOLKANE-Solvents-iconSOLVOKANE® S is SOLVOKANE® with content of a special choosen surfactant. SOLVOKANE® S is designed for drying applications and typically operates in a three-stage vapor degreasing/drying unit together with normal SOLVOKANE® in the final rinse.

SOLVOKANE® S is SOLVOKANE®, an azeotropic, non-flammable mixture of SOLKANE® 365mfc (1,1,1,3,3-pentafluorobutane) and t-DCE (1,2-dichloroethlylene), with an added specialty surfactant. 

The phase-out of conventional solutions (e.g., CFCs and HCFCs) has required alternative products. SOLVOKANE® S offers product characteristics which are very close to HCFC 141b and CFC 113, with a Kauri Butanol (Kb) Index of 25. The solvency power versus common contaminants is stronger than the Kb value (21.7) would suggest.

EPA/SNAP approved, SOLVOKANE® S is a new generation, environmentally-compatible solvent. A volatile, colorless liquid without ozone depletion potential (ODP = 0), it has a relatively low global warming potential (GWP), as well as other properties which make it a superior replacement for CFCs and HCFCs.

Features and Benefits

  • Fast drying with no-residue 
  • Low temperature with a boiling point 36 ºC 
  • Non-flammable azeotrope 
  • Excellent toxicity characteristics 
  • Drop in replacement for high cost HFC/HFE solvents 
  • Cleaning similar to R 141b and R 113 
  • Can be used as a starting point or component for more complex/customized solvent formulations
