Fluoroaliphatic Polyoxyethylene
Fluorosurfactant |
| |
| |
MASURF FS-425 is characterized as a 25% active fluoroaliphatic polyoxyethylene
fluorosurfactant in a water/glycol ether solution. FS-425 is a nonionic
fluorosurfactant with the ability to contribute exceptional wetting,
spreading and leveling properties to a wide range of systems. With
typical use levels of 50-500ppm, MASURF FS-425 is effective at very
low concentrations, and together with traditional hydrocarbon surfactants,
can contribute properties not possible with either material alone.
MASURF FS-425 is stable in anionic and cationic systems, effective
in high or low pH, and recommended in a wide range of applications.
With unique surface diffusion properties, FS-425 imparts anti-soiling
and improved weatherability when formulated into Coatings
and Sealers. In Performance Polymer
Systems, FS-425 acts as a coupling agent for fillers, and imparts
anti-soiling performance. In Plating Applications,
FS-425 improves stability of bath and contributes to brightness and
adhesion. In Ink (flexographic or
gravure) applications, overall performance can be improved by using
a blend of Masurf FS-425 with acetylenic surfactants, and is useful
in avoiding “solvent shock” in ink/solvent letdowns.

MASURF FS-425 is characterized as a 25% active fluoroaliphatic polyoxyethylene
fluorosurfactant in a water/2-butoxyethanol solution. FS-425 is an
effective wetting and interfacial tension reducing agent with very
good alkaline stability. The formulation below illustrates this effect.

When formulating Hard Surface cleaners, the acronym "TACT" should
be kept in mind: T (Time), A (Agitation), C (Concentration) and T
(Temperature). Leverage any component of TACT for improved cleaning
performance and efficiency. MASURF FS-425 is effective at reducing
the required contact time (T) by increasing wetting performance and
penetration, and increasing the effective concentration (C) by lowering
the interfacial tension between the detergent surfactants, monoethanolamine,
solvents and the polymer floor finish.
Ink (flexographic or gravure) applications
Unlike many fluorosurfactants, Masurf FS-425 is a low foamer and performs
in inks to deliver improvements in flow, wetting, leveling, gloss,
and reduction of surface imperfections.
Acetylenic alcohol based surfactants provide exceptional dynamic surface
tension reduction, getting to their minimum surface tension faster
than most fluorosurfactants. However, the acetylenic alcohol based
materials can only reduce the surface tension to a level like most
hydrocarbon surfactants. In ink applications (whether flexographic
or gravure), performance improvements can be made by using a blend
of fluorosurfactants with the acetylenic alcohol based surfactants
to get the instant reduction, followed in the next instant by the
fluorosurfactant surface reduction to the lowest possible surface
tension possible. Dynamic surface tension reduction data consistently
show that the way to get the fastest reduction AND the greatest magnitude
of reduction (which ultimately is what improves leveling and decreases
ink wicking the most) is to use a 1:1 mixture of a nonionic fluorosurfactant
like Masurf FS-425 in combination with an acetylenic alcohol based
surfactant.
Additionally, nonionic fluorosurfactants such as Masurf FS-425 are
often are helpful in avoiding “solvent shock,” when ink concentrates
are “letdown” to final concentrations. Mixing in a small amount of
FS-425 to the concentrate immediately prior to letting it down can
avoid solids coming out of solution.
Masurf
FS-Fluorosurfactant evaluation guidelines
Masurf FS-Fluorosurfactants are effective at very low concentrations,
typically 50-500 ppm, and can act synergistically with hydrocarbon
and/or silicone surfactants. Evaluate in aqueous formulations at 0.1%
active Masurf FS-Fluorosurfactant initially, then optimize by successively
reducing the FS concentration by ½.
Masurf FS-Fluorosurfactants and Masurf FP-Fluoropolymers do not contain
PFOS/PFOA. Masurf FS and FP products are manufactured with telomerization
process fluoroaliphatic intermediates that do not contain, release
or have been shown to degrade to perfluorooctane sulfonate (PFOS)
or perfluorooctanoic acid (PFOA). |
