3M Novec 73DE Engineered Fluid Heavy Duty High Solvency Degreasing
Type: Heavy Duty Degreasing Solvent
Boiling Point: 48°C
KB Value: 83
Surface Tension: 19.9 dynes/cm
Packing: 5KG / 20KG drum
3M Novec 73DE Engineered Fluid is a high-performance, heavy-duty vapor degreasing and immersion cleaning solvent designed to replace n-propyl bromide (nPB), trichloroethylene (TCE), ozone-depleting HCFCs, and high-GWP HFCs. With an exceptional Kauri-Butanol (KB) value of 83 — the highest in the Novec series — this nonflammable fluid delivers superior solvency for removing heavy greases, oils, waxes, silicones, and non-polar flux residues from complex components. Its low surface tension of 19.9 dynes/cm ensures excellent wetting and penetration, while its boiling point of 48°C enables efficient vapor degreasing with reduced energy consumption.
Novec 73DE offers a compelling combination of performance and sustainability — zero ozone depletion potential, an ultra-low GWP of 47, and zero ozone depletion potential. Compared to aqueous cleaning, vapor degreasing with Novec 73DE delivers faster cycle times, lower energy usage, and improved cleaning of parts with complex geometries. With a favorable safety profile (100/200 ppm exposure guideline), nonflammability, and t-DCE not classified as a Hazardous Air Pollutant, Novec 73DE provides a cost-effective, environmentally responsible solution for the most demanding degreasing applications.
