TUW-4430 Fluorosurfactant

TUW-4430 Fluorosurfactant is a non-ionic fluoropolymer supplied as a pale yellow liquid with a surface tension of 18–22 mN/m and a specific gravity of 1.30–1.50. It is an additive rather than a heat-transfer fluid: at 0.1–5% loading it pushes a formulation's surface tension below what hydrocarbon surfactants can reach.
Lower surface tension translates into better levelling, wetting and crater resistance in coatings and inks. In cleaner formulations TUW-4430 Fluorosurfactant improves penetration and anti-soiling behaviour, especially on low-energy substrates such as PET, PP and fluoropolymers. In resin systems it improves mould release and oil resistance, and in agricultural PE film it raises light transmission while suppressing fogging. It maps to the 3M FC-4430 application space for formulation substitution.

 

- Appearance: Pale yellow liquid
- Surface tension: 18–22 mN/m
- Specific gravity: 1.30–1.50 g/mL
- Chemistry: Non-ionic fluoropolymer
- Recommended dosage: 0.1–5%
- Solubility: Compatible with most organic solvents and resin systems

 

1. Coatings and inks — Levelling, slip and gloss; eliminates craters, orange peel and fish eyes in solvent-borne and UV systems.
2. Cleaners and cleaning baths — Lower surface tension for better penetration of oils, fingerprints and particles, and wetting of low-energy substrates.
3. Resin and plastics additives — Improved flow, mould release and oil resistance in engineering-plastic compounds and masterbatches.
4. Agricultural film and functional coatings — Anti-fog and higher light transmission in PE film; anti-soiling and easy-clean performance in coatings.

 

TUW-4430 Fluorosurfactant is a concentrate. Pre-dilute to a 10% master batch in the formulation solvent before adding 0.1–5% to the main system, otherwise local over-concentration can gel or precipitate. It is compatible with anionic and non-ionic systems; run a bench trial before use in strongly acidic or alkaline formulations.
Store in a cool, ventilated, dry place, kept sealed and out of sunlight. Use the drum promptly after opening — prolonged exposure lets solvent evaporate and shifts the concentration. Wear gloves and goggles, avoid ingestion and eye contact, and dispose of waste under local regulations.
More is not better: 0.1–0.5% usually brings coating surface tension below 22 mN/m, while above 1% intercoat adhesion can drop; cleaner formulations may run 1–3% but foam height must be checked. Run a ladder test and stop at the level that just removes craters.
Dose TUW-4430 Fluorosurfactant by weight into the let-down solvent, never into the neat resin, and record the batch so that a later adhesion problem can be traced back to the loading.

 

5 kg and 25 kg pails as standard, with 1 kg samples available. Stocked in South China with TDS, SDS and batch COA, and we can support bench trials.
TUW-4430 Fluorosurfactant is also available pre-diluted to a 10% master batch for lines that cannot handle neat dosing.
