The high ionization potential of fluorine and it's low polarizability leads to extremely weak inter- and intramolecular interactions, and the extremely low surface energy of treated surfaces. It is the extremely low surface energy that allows treated surfaces to repel both water and oil, thus imparting soil and stain protection. Other surface treatment chemistries that don't rely on fluorine, such as waxes and silicones, result in a much higher surface energy, that while repelling water, actually attract oil based soils and stains.
MASURF FS-130A and FS-910 can be used as Surface
Protectants to impart water and oil repellency with soil and
stain protection to a range of surfaces including hard surfaces such
as Concrete, Saltillo Tile, Limestone and
Marble. MASURF FS-130A is characterized as a 30% active fluoroaliphatic
phosphate ester fluorosurfactant in an aqueous solution, contributes
exceptional oil resistance, rheology and surface modification, spreading
and leveling properties to a wide range of systems. MASURF FS-910
is a high performance fluorooligomer that will impart water & oil
repellency to protect virtually any surface
from both water and oil based soils and stains, and will not
change the appearance, hand, color or impart an odor to treated surfaces.
Refer to the individual Product Data Sheets for individual physical
properties and for other useful applications.
The unique performance properties of MASURF telomer based fluorosurfactants, polymers and oligomers are attributed to the fundamental properties of fluorine chemistry. Fluorine is the most abundant member of the halogen family with ionic metal fluorides being the most common chemical forms of fluorine found in nature, such as fluorspar (CaF2). The strong polarity of the carbon-fluorine bond, makes it one of the strongest in nature. This very strong, high energy bond contributes to the stability of fluoroaliphatics. The unique stability of the carbon-fluorine bond, with the time-tested telomerization process insures that 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).

| Handling Information |
Wear
safety glasses with side shields or goggles to avoid eye contact.
Wear appropriate gloves to avoid skin contact. In spray applications,
use a coarse spray device that does not produce fine particles such
as a trigger sprayer or pressurized dispenser with particle size production
of greater than 15 microns. Adjust spray pressure to keep particle
size greater than 15 microns. Based on properties displayed by similar
materials, the fluoroaliphatic component of this solution, if dispersed
as a fine particle, may have the potential to induce a pneumonia-like
condition. Do not aerosolize or atomize.
For further Safety Information, please refer to the Material Safety
Data Sheet.
PERFORMANCE
PROPERTIES/TEST CONDITIONS
In this product Application Review, to ensure that the results weren't
unduly influenced by additive ingredients, MASURF FS-130A and MASURF
FS-910 were prepared in simple 1:10 dilution in the solvent itself;
deionized water for FS-130A and Odorless Mineral Spirits (OMS) for
FS-910. As such, this data is representative of the performance of
the base ingredient only, and further performance enhancements can
be achieved through appropriate formulation. Once diluted, the material
was applied at a rate of 1 gallon per 400-600 sq. feet, and allowed
to cure for a minimum of 24 hours unless otherwise stated.
Water Holdout Evaluation
Water Holdout is a basic performance measurement for Surface Protectants.
The ability of a treatment to withstand penetration by water is a
visual guide to product performance. As is illustrated below, Masurf
FS-130A and FS-910 are very effective at water repellency versus untreated
Stone Surfaces:
Water Holdout was measured by applying a pool of water (3-5 droplets)
and observing the time (in minutes) required to show evidence of absorption
into the treated substrate (darkening under the liquid pool being
the most common indicator). Differences in water beading (contact
angles) were noted but are not reported. A maximum limit of 3 hours
was established to negate impact from evaporation processes on the
test results.
Water & Oil Repellency Evaluation
Water & Oil Repellency is a differentiating performance measurement
for Surface Protectants. The ability of a treatment to withstand penetration
by aqueous solutions of increasing solvent strength (isopropanol in
water), and oils of increasing solvent strength are the key differentiators
between fluorocarbon based Protectants and all others: while waxes
and silicones exhibit water repellency, they do not exhibit oil repellency.
The benefit to this feature is in the ability of fluorocarbon treated
surfaces to resist degradation by detergents, solvents and chemicals
for long lasting, durable Surface Protection.
As is illustrated below, Masurf FS-130A and FS-910 are very effective
at water & oil repellency versus untreated Stone Surfaces:
Water Repellency (DuPont Method) was measured by applying 3 drops
of test liquid and observing wetting of the surfaces. If the drops
were repelled for longer than 10 seconds the surface was judged to
be repellent to that test liquid. Six test liquids ranged from 2%
Isopropyl Alcohol (1 rating) to 100% Isopropyl Alcohol (6 rating).
The higher the concentration of Isopropyl Alcohol, the more repellent
the surface.
Oil Repellency (AATCC Test Method 118-1989) was measured by applying
3 drops of test liquid and observing wetting of the surfaces. If the
drops were repelled for longer than 30 seconds the surface was judged
to be repellent to that test liquid. Test liquids ranged from mineral
oil (1 rating) to Decane (6 rating). The higher the number test liquid
the more repellent the surface. Decane (6 rating) is more difficult
to repel than Dodecane (5 rating), which is more difficult than Tetradecane
(4 rating) and so forth.
Soil Repellency Evaluation
Soil Repellency is the "real world" performance measurement for Surface
Protectants. The ability of a treatment to withstand a range of staining
materials is "cost savings" derived from a treatment, by extending
the life of a surface or surface coating. The feature of Masurf fluorochemcal
Surface Protectants is in the ability to resist staining not possible
with any non-fluorocarbon based protectant.
As is illustrated below, Masurf FS-130A and FS-910 are very effective
at soil repellency versus untreated Stone Surfaces:
Stain Repellency was measured after appropriately cleaning/drying
the substrate to ensure uniformity. The top surfaces of the substrates
being treated were brush applied with care to ensure adequate coverage,
then allowed to dry for a full 72 hours before staining. The following
eight food stains were then placed on the treated substrates and allowed
to remain for two hours: red wine, coffee, cola, tea, corn oil, dirty
motor oil, spaghetti sauce, and a standard red drink. After this period,
the food stains were blotted, and the substrates were rinsed with
tap water and allowed to dry before rating.
Stains remaining on the substrate after cleaning were rated visually
as follows:
Rating |
No.Stain Intensity |
0 |
no stain |
1 |
light stain |
2 |
moderate stain |
3 |
heavy stain |
The ratings against each individual stain were summed, and are shown
in the graph below. Please note: no resistance
to any stain would result in a score of 24. The lower the total, the
more resistant the treated substrate is to the stains employed. A
perfect score would result in a ZERO rating.
Also Note: highly porous concrete block was selected for stain testing,
to exaggerate the staining effect. Better results are obtained on
pavement concrete or smooth concrete flooring.
