FREQUENTLY ASKED QUESTIONS ABOUT ULTRA EVER DRY
1. How does ULTRA EVER DRY work?
The bottom coat bonds to most materials and acts as a primer. It
provides a consistent material for the top coat to bond to while interacting
with the top coat to self-assemble the surface, creating finely textured
geometry. This surface is comprised of patterns of geometric shapes and
billions of interstitial spaces. There are "high points" in the surface that
help to create a low surface energy, which causes droplets of water to touch
a very small percentage of the coating. The water in the droplet that does
not touch these "high points" is held together by intermolecular cohesive
forces of the water molecules.
2. What
does "superhydrophobic" mean?
ULTRA EVER DRY surface
protection coating creates a solid/liquid contact angle of 160-175 degrees
in air. Well-known windshield water repellents have a contact angle closer
to 110 degrees and are only hydrophobic. A superhydrophobic contact angle
allows for the self-cleaning properties associated with ULTRA EVER DRY.
3. How long will ULTRA EVER DRY coating
last?
The ULTRA EVER DRY formula is susceptible to
environmental conditions such as UV. This coating will offer approximately
one year of outdoor life before recoating of the top coat would be required.
When used in indoor or covered applications outdoors, the coating should
last for a year or more. If the top coat has diminished due to environmental
conditions, simply reapply the top coat to regain the superhydrophobic
properties (assuming the bottom coat is still present). ULTRA EVER DRY
coating is also susceptible to abrasion.
4. What is the working temperature range for
ULTRA EVER DRY?
The working temperature range for a coated
surface is from -34°C to 149°C once it has been applied. We would recommend
further testing for any application that will be exposed to temperatures
above 149 °C. The coating should be applied at temperatures between 10°C to
32°C.
5. What materials will the ULTRA
EVER DRY coating adhere or bond to?
Please note that the
coating has a hazy translucent white appearance. Almost any material is a
candidate for application: steel, aluminum, other metals, plastic, leather,
fabric, wood, concrete, etc. The coating can be applied to and will bond to
smooth surfaces. Preparing an already cleaned surface with heavy-duty scotch
brite and/or sanding the surface with 320-800 grit sandpaper will improve
adhesion. ULTRA EVER DRY is not recommended for use on acrylics due to the
high solvent content.
6. How
abrasion-resistant is ULTRA EVER DRY?
ULTRA EVER DRY surface
protection is significantly more abrasion resistant than previous
superhydrophobic materials, registering a result of 30 cycles with a CS-10
wheel and 1000 g load on the Taber Abraser before droplets no longer roll
off the coating at a slope of 5 degrees from horizontal. The coating may
still be superhydrophobic at this point, but droplets may "pin" or stick in
the abraded area, and may not roll off until the substrate is tilted to a
greater degree. If abrasion is a concern, testing is recommended. If the
coating is removed due to repeated or severe abrasion, it can be reapplied.
7. Will the coating still work if the top
coat is largely removed due to abrasion?
Perhaps. In many
situations, the superhydrophobic nature of the material may be diminished
but the remaining top coat and bottom coat still provide the functionality
of keeping the coated material from getting wet, iced up or corroding. This
is application dependent.
8. What
color is the surface coating?
The standard product is a hazy
translucent white. We do not have a transparent formula at this time. Custom
colors are not available at this time. It is recommended to try the coating
in an inconspicuous area first if the color is important.
9. How many square meters can a liter cover?
6 square meters at a dry film thickness of 13 microns.
10. How long does ULTRA EVER DRY take to cure?
Bottom Coat: Allow 30-60 minutes of dry time before applying the top
coat. A heat gun/blow dryer may be used on a low setting to decrease dry
time.
Top Coat: The coating will become superhydrophobic within 15-30
minutes of the top coat application. Allow 2 hours of additional dry time
for good results.
11. What is the
shelf life of ULTRA EVER DRY and what temperature should it be stored at?
Typically, the shelf life of the product will be four years when stored
between 4°C and 40°C.
12. Does UV
affect ULTRA EVER DRY?
ULTRA EVER DRY coating is adversely
affected by ultraviolet (UV) light, reducing its useful life. Additional
ULTRA EVER DRY formulas are being developed to reduce the effect of UV
light.
13. How chemically resistant is
ULTRA EVER DRY?
As with most materials and coatings, this will
depend on the chemical. In general, it is resistant to a wide range
including many water-based acids and bases. It may or may not be compatible
with oil-based liquids, since these substances have varying values of
surface tension and liquids with low values of surface tension are not
compatible with ULTRA EVER DRY. Testing may be required to ensure proper
compatibility. ULTRA EVER DRY surface protection will not work with organic
solvents including, but not limited to: acetone, xylene, t-butyl acetate,
naphtha, MEK, etc.
14. What known
chemicals are incompatible with ULTRA EVER DRY coating?
Soaps
and detergents will cause the surface of the coating to "wet-out". Once
these chemicals are removed (using low-pressure water), the
superhydrophobicity will generally return. Alcohols and solvents will
dissolve/remove the coating.
15. How
well does ULTRA EVER DRY stand-up to acids/bases?
Strong acids
and bases are typically not a problem. Testing has been completed with
sulfuric, hydrochloric, and phosphoric acid with excellent results. We have
also seen good results shedding strong caustic and some bleach solutions.
16. Will ULTRA EVER DRY help prevent
corrosion?
Yes, ULTRA EVER DRY surface protection coating is
corrosion resistant. Increasing the bottom coat thickness will increase
longevity. Applying ULTRA EVER DRY on top of existing painted surfaces,
polyurethane coatings or other treated surfaces will increase the
effectiveness and longevity of the pre-existing treatment.
17. How is ULTRA EVER DRY coating applied?
ULTRA EVER DRY surface protection coating is best applied using a spray
method, either with traditional air-compressor driven HVLP paint sprayers,
airbrush paint sprayers or by the Preval Sprayer. NOTE: Both parts (top and
bottom coat) are required for all applications of ULTRA EVER DRY. We do not
have data showing consistent results with other coating methods at this
time.
Note: With all sprayer options, it is important to adjust the
volume to allow ULTRA EVER DRY to be applied in a fine mist.
Preval
Sprayer: For small jobs. Remove filter at the bottom of the dip tube before
use.
HVLP Spray Gun: For medium/large jobs. Use Warwick 881H or
similar, 1.7 mm needle/nozzle set. Air conditions: cool, dry, 40-45 psi line
pressure, 24-28 psi working pressure. Create a fine mist.
Airbrush:
For small jobs. Use Iwata NEO BCN or similar, tip size = 0.5 mm. Air
conditions: cool, dry, 10-60 psi working pressure. Create a fine mist.
See specific sprayer manufacturer instructions for safe and proper
usage.
18. Is it electrically
conductive?
No, it is not electrically conductive. It can be
safely used to coat electric motors, switches, electrical components,
electronic subjected to the elements, light fixtures, etc.
19. What does this product do to the transmission
of air through a material?
The passing of air through the
coating is dependent on the substrate. There are surfaces where the coating
can act as a liquid repellent under low pressures but allows for the
permeation of gases or vapor. If the bottom coat is applied too thick and
makes a continuous film across the pores of the substrate, then air
transmission will be diminished.
20.
Is ULTRA EVER DRY surface protection coating flammable when it is dry?
Polymer binders do not offer flammability resistance as polymers are
carbon-based molecules and therefore will eventually burn or melt. Please
note, however, that the dry coating thicknesses are generally only about 1
mil (25 microns). We expect the overall flammability will be determined by
the article being coated. We advise application-specific testing if
flammability is a concern.
21. If
ULTRA EVER DRY is applied to fabrics, will it wash off?
Yes,
after few washes and in some cases after a single wash.
22. Can you use ULTRA EVER DRY coating where it
is submerged in water or liquid?
This depends on the type of
substrate, the depth of the submersion, the length of time the material is
submersed, and the specific application. Steel coated with ULTRA EVER DRY
has been immersed in salt water for 30 days at depths of less than 30 cm
without any corrosion effect. The surface may lose superhydrophobicity based
on the saturation of the Top Coat but can remain corrosion-free because of
the protective Bottom Coat layer. Additionally, increased thickness of
Bottom Coat (applied properly with multiple thin passes) can increase the
longevity in these applications. In all cases, the Top Coat will eventually
saturate and wet-out over time, with the saturation time being related to
the depth of the submersion.
23. Do
you recommend using ULTRA EVER DRY inside of a pipe with constantly flowing
liquid?
No, this is not a good application, unless the fluid
is slow-moving (laminar flow). In most cases, the liquid flowing through
piping will be turbulent, causing ULTRA EVER DRY surface protection to
abrade away.
24. It seems like the
ULTRA EVER DRY coating is rubbing off on my hands. Is that normal?
The whitish coating that comes off in your hands if you rub it is excess
top coat particles that did not bond to on the bottom coat. NOTE: Due to the
natural oils in the skin, excessive handling with bare hands of treated
materials can cause a reduction in performance.
25. What is the return policy for ULTRA EVER DRY
coating?
All sales are final. We are unable to accept returns
on the product because of the shelf life (4 years). ULTRA EVER DRY is
stamped with a "best by" date and because of that, returns are not
practical.
26. Is ULTRA EVER DRY
coating comprised of, or is it produced using, Ozone Depleting Substances
(as defined in the Kyoto Protocol and listed in Annex A of the Montreal
Protocol, as amended)?
No, ULTRA EVER DRY is not produced
using any Ozone Depleting Substances (as defined in the Kyoto Protocol or
listed in Annex A of the Montreal Protocol, as amended.
27. Does the ULTRA EVER DRY prevent powder
accumulation on metal walls?
If there is no water or other
liquid available to clean the coating, then the coating is not effective. It
is not smooth or slick, it is actually a rough surface and may actually end
up holding more powder in this application.
28. Is silicone one of the ingredients in the
ULTRA EVER DRY product?
There is no silicone, but there is a
non-crystalline, fumed silica in the Top Coat (it is listed on the Safety
Data Sheet).
29. Is the proprietary
additive toxic?
All proprietary ingredients are non-hazardous.
30. What is the NFPA and HMIS information
for ULTRA EVER DRY surface protection coating?
For the bottom
coat:
HMIS: Flammability 3 /health 1 /hazard 0 /personal protection
ratings H
NFPA: Flammability (Red) 3 /health (Blue) 1 /hazard (yellow) 0
/ Special (white) empty
For the acetone top coat:
HMIS:
Flammability 3 /health 2 /hazard 0 /personal protection ratings H
NFPA:
Flammability (Red) 3 /health (Blue) 2 /hazard (yellow) 0 / Special (white)
empty
31. Can I use ULTRA EVER DRY on
my car?
Our product can be used on cars but we recommend only
using it underneath the vehicle. It is not recommended for use on body
panels or windows/windshields because of the translucent white color. It is
recommended to try the ULTRA EVER DRY in an inconspicuous area first if the
color is important. It will cover a gloss paint with a dull, matte finish.
Some exceptions to this recommendation are using ULTRA EVER DRY on work
vehicles such as cement trucks or off-road vehicles where aesthetics are not
as important as cleanliness, anti-corrosion, anti-icing, and maintenance.
32. Can ULTRA EVER DRY surface protection
coating be used to prevent graffiti?
Surfaces coated with
ULTRA EVER DRY will not prevent oil-based paints from being applied, due to
the solvents in the formulas. It has been shown to be somewhat effective
with water-based paints however the majority of spray paints are oil-based.
33. Can I spray this on the bottom of my
boat?
We do not recommend applying ULTRA EVER DRY surface
protection coating to the bottom of a boat or ship. The flow is quite often
turbulent in these areas, and this high energy (and high velocity) flow can
damage and/or remove the coating. ULTRA EVER DRY may have potential on
slower-moving and less turbulent applications, such as the bottoms of canoes
or kayaks, but we do not have data for these applications yet.
34. Can I use ULTRA EVER DRY on my skis,
snowboard or surfboard?
We have not had the opportunity to
test ULTRA EVER DRY for these applications.
35. Will spraying ULTRA EVER DRY on my phone make
it waterproof?
ULTRA EVER DRY does protect electric
connections from water and moisture and is non-conductive, but ULTRA EVER
DRY is not clear. It dries to a translucent white color, so we cannot
recommend spraying phones with it.
