Techspray PWR-4 Solvent 3910-G, 1 gallon, 100% US Made, Heavy-duty, Low GWP degreaser, PFAS FREE

Ideal Replacement (PFAS FREE) for Novec 71DE, 72DA, 72DE & 73DE

PWR-4 Solvent 3910 is ideal where a safer, nonflammable and cost effective cleaner is required. It has a much lower Global Warming Potential (GWP) than other fluorocarbon containing solvents that contain HFC and most HFEs. This solvent is PFAS FREE.

This innovative solvent is much safer than the four most common industrial solvents: TCE, nPB, perchloroethylene (PERC) and methylene chloride and quickly cleans the difficult baked-on R, RMA & no-clean fluxes from electronic assemblies. It is also a very effective cleaner for precision cleaning removing light, medium or heavy greases.

PWR-4 Solvent 3910 has azeotrope properties that allow it to maintain stable properties as it is cycled in a vapor-degreaser. It is neither reactive nor corrosive to metals commonly found in the construction of vapor-degreasers. It is stabilized to minimize any chances of acidification.

All ingredients in Precision-V Solvent 3910 are synthesized in the United States and the final product is compounded in the United States to provide the most secure supply chain.

Vapor Degreaser Setting Guidelines

• Boiling point – 118°F / 48°C
• Boil sump temp set – 127°F / 53°C  
• High solvent temp set – 136°F / 58°C
• Refrigerant high temp set – 109°F / 43°C

NOTE: As with all vapor degreaser equipment and processes, observe all safety precautions, guidelines and operating rules associated with these units. Failure to do so may put operations personnel at risk. For example avoid excessive vapor losses, loss of refrigeration or excessive boil sump heat. PWR-4 Solvent 3910 has no closed cup flash point however keep any ignition source away from the vapors. Ensure all equipment is operated per the manufacturer’s guidelines and instructions. If in doubt, contact your manufacturer immediately.
