TUW-39 Next-Generation Fluorinated Solvent
Overview
TUW-39 is a high-performance fluorinated solvent developed for demanding industrial cleaning and heat-transfer applications. Engineered as a sustainable alternative to traditional ozone-depleting and high-GWP solvents, it provides excellent solvency, material compatibility, and operational safety without compromising environmental responsibility.
Key Features & Benefits
Non-Flammable: No flash point, ensuring safe handling and operation.
High Cleaning Performance: Effectively removes particles, ionic residues, solder flux, adhesives, silicone oils, drawing oils, and lapping compounds.
Drop-in Replacement: Direct substitute for HCFC-141b, HCFC-225, HFCs, and HFEs in vapor degreasing systems.
Excellent Material Compatibility: Safe for use with ferrous and non-ferrous alloys (aluminum, copper, magnesium, nickel, steel, stainless steel, titanium, zinc) as well as most polymers and elastomers.
Environmental Profile: Near-zero Ozone Depletion Potential (ODP ≈ 0) and ultra-low Global Warming Potential (GWP < 1).
Regulatory Compliant: RoHS compliant, not classified as SVHC, and not a Hazardous Air Pollutant (HAP).
Recyclable & Reusable: Suitable for recovery and reuse, reducing waste and operational costs.
Typical Applications
Precision cleaning of hard disks, graphics cards, and electronic assemblies
Vapor degreasing
Silicone oil dilution and removal
Particle removal from sensitive components
Heat-transfer fluid applications
