Electrical Contact Cleaner (Defluxing) & Vapor Degreasing Solvent




FluoSolv® AP is a proprietary blend of non- flammable hydrofluoroethers (HFEs) and trans-1,2-dichloroethylene (t-DCE) and alcohol engineered for defluxing as well as white residue removal.


FluoSolv® AP is a drop-in replacement for defluxing blends of n-propyl bromide (nPB) and similar vapor degreasing solvents.  It can also be used as a substitute for other cleaners such as Asahi AK-225 (blend of HCFC-225 ca/cb) & HCFC-141b both of which are ozone-depleting substances and have been banned from production.


FluoSolv® AP solvent blending technology leverages the chemical solvency of the fluid as well as its physical properties such as high density, low surface tension and low viscosity for optimal performance.  Our research has shown that to clean metal surfaces in the shortest amount of time the solvent must flow extremely close to the surface to “catch & release” contaminants

User Benefits  



NuGenTec FluoSolv® AP is ideally balanced to deliver performance, worker safety, and desirable environmental properties.

  • Non-ozone depleting chemical (ODC)

  • Drop-in replacement; no equipment    


  • Low global warming potential (GWP)

  • Low toxicity; high allowable exposure limit (AEL);

  • No ceiling on instantaneous exposure

  • Chemically stable; will not go acid


Material Compatibility


FluoSolv® AP is compatible with all metals, ceramic and other non-conducting materials.  Most elastomeric materials are compatible except fluoroelastomers such as Viton & Kalrez which tend to swell. It is recommended that all materials be tested prior to use.   See Table 1.

                                          Compatible                        Additional Testing Required


   Metals                  Aluminum, Copper, S/S                                  -

                                 Titanium, Brass, Tungsten               


   Elastomers          Neoprene, Butyl Rubber                      Viton, Kalrez


   Plastics                HDPE, PTFE, Nylon, PVC                  Acrylic, ABS

                                  Epoxy, Phenolic

Worker Safety
Data from acute toxicity studies of various ingredients have demonstrated that FluoSolv® AP blend has low toxicity. It has a calculated AEL (Acceptable Exposure Limit) of 335 ppm based on its individual components.  None of the ingredients in FluoSolv® AP have any chronic or acute toxicity associated with them which makes it a worker-friendly solvent.  


Please refer to the MSDS for information on detailed exposure limits and toxicity-related data.


NuGenTec FluoSolv® AP exhibits no closed cup or open cup flash point and is not classified as a flammable liquid per established definitions by NFPA or DOT, however being volatile, vapors may become flammable in air. Flashpoint data and vapor flammability limits in air are shown in Table 3 below.


FluoSolv® AP is thermally & chemically a very stable solvent.  It is non-reactive, has low water solubility and will not oxidize or degrade when exposed to air. It is not affected by any sunlight or other sources of UV radiation.  Common industrial practice should be implemented for storage; keep away from human food source and extreme temperature conditions.  Freezing temperatures will cause the drums to compress and hot conditions will balloon the drum. The product, in any case, is perfectly usable.

Solvent Recycling

FluoSolv® AP is a stable azeotropic blend easy to reclaim and reuse by a simple distillation process.  Commercially available modular recycling units can easily be added to realize sizable savings in solvent usage.  Solvent recovery yields are typically in the range of 80 to 95%.
