TUW-72DA Precision Cleaning Fluorinated Fluid | NO PFAS | Replacement for 3M™ Novec™ 72DA | Zero ODP, Non-Flammable

Overview
TUW-72DA is a high‑performance fluorinated azeotropic cleaning agent independently developed by Shenzhen Huayi Brothers Technology Co., Ltd. (TUW) for precision cleaning applications. It is an ideal direct replacement for 3M™ Novec™ 72DA and is PFAS‑free, helping customers mitigate supply chain risks caused by the phase‑out of PFAS‑containing products. The ternary azeotropic formulation ensures stable composition during prolonged use and distillation recovery, guaranteeing consistent cleaning performance.

Key Features

• Strong cleaning power – Effectively removes flux residues (rosin‑based), oils, greases, waxes and particulate contaminants.

• Low surface tension (15.2 mN/m) – Excellent wetting and penetration into microscopic gaps, blind holes and complex geometries.

• Low viscosity (0.65 cSt) – High fluidity for easy penetration and quick drainage.

• Completely volatile – Dries rapidly without water spots or residues; no oven drying required, reducing process time.

• Non‑flammable – No flash point; safe for use in critical environments with strict fire safety requirements.

• Low toxicity – Low hazard to human health when handled properly, meeting industrial hygiene standards.

• Excellent material compatibility – Compatible with most metals, plastics and elastomers; does not damage sensitive parts.

• Environmentally friendly – Zero ODP (ozone depletion potential), low GWP (~170), and PFAS‑free. An ideal substitute for traditional solvents such as CFCs, HCFCs, HFCs, nPB and chlorinated solvents.
