Plastic-Mask 2930 is specifically
formulated for both indoor and
outdoor protection against
scratching and marring of acrylic
windows and windshields during the
handling, transportation, and
storage of rotary and fixed wing
aircraft. It is UV stabilized and
will not crack or discolor for up to
a year outdoors and well beyond
indoors. It remains very pliable and
easy to peel leaving no residue or
effect on the acrylic surface. It is
stabilized against brittleness and
is not softened or penetrated by
most water-based and solvent based
compounds. |
|
|
|
|
| |
Plastic-Mask 2930 is VOC free with water
being the only vapor released during
the curing process. Plastic-Mask is
applied via airless or air assist
sprayer. Plastic-Mask
peelable coating is non flammable
and non combustible as supplied and
when the dry strippable film is
formed and is also low hazard (see
separate Health & Safety Data). |
|
|
|
|
| |
Plastic-Mask 2930 is a water
resistant, peelable temporary
protective that air dries quickly,
leaving a tough, clear flexible
coating that is easily removed from
a variety of surfaces. Plastic-Mask
2930
represents the ultimate in
waterborne removable coating
technology. |
|
|
 2930
is a water based masking compound that
forms a tough clear plastic film with
controlled adhesion to plastics to
give excellent surface protection and
easily strippable. It is designed to
apply on flat sheets of plastic prior
to thermoforming. It is engineered to
be sprayable as masking film for
heat forming and decorating acrylic,
polycarbonate and Abs sheets.
The clear film of Plastic-Mask 2930
once dry can be run through the full
process cycle of thermoforming with
the part with any shape of part and
with the dry film in direct contact
with die. The dry peelable film of
2930 remains dry and tack free even
while hot. When coarse material or
very tight dies are being coated talc
or powder dusting may help.
Application and dry film of 2930
allows full protection of the plastic
sheet from the time is inspected in
the flat through forming and
fabrication process such as drilling,
routing, sheating, etc.
Thermoforming is a manufacturing
process where a plastic sheet is
heated to a pliable forming
temperature, formed to a specific
shape in a mold, and trimmed to create
a usable product. The sheet, or "film"
when referring to thinner gauges and
certain material types, is heated in
an oven to a high-enough temperature
that it can be stretched into or onto
a mold and cooled to a finished shape.

Plastic-Mask 2930 should be used as
received. It can be applied by
airless spray, paint roller, or
brush. The coating dries upon water
evaporation. Wet coating is
milky(white). Plastic-Mask 2930
should be applied to form a dry film
in the range of 3 to 10 mils(.003"
to .010") thick. Application
temperature is ambient to no lower
than 50F.
2930 can be
used as minimum as 3 mil dry film
thickness for both fabrication
damage resistance and easy
strippability.
2930 can be
applied to a vertical surface in one
pass using standard spray guns (e.g.
Devilbiss MBC gun, FF
NOOZZLE,# 765 AIR CAP). Atomization
Pressure: 75pounds per sq. inch
minimum and sufficient pressure on
the material container or port
to force the coating up to the
nozzle of the gun.
Airless
spray gun can also be used
such as Binks model 43F gun
and a 25:1 ratio pump or graco
#205-904 with a 163-618 insert
and a 28:1 ratio pump. |

Application may be Lamb’s wool Ships
Roller or airless spray equipment with
21 thou tip size.
Take
measures to protect and Mask areas
against overspray. Be careful
and avoid spraying into small openings
where the coating may become thin and
subsequently difficult to remove. Must
try to achieve a defined edge at the
end of the area to be coated by taping
the outer edges or by other methods.
Do not apply during rain or frost.
Dry Film Thickness : Once a
film of 2930 goes through the
heat cycle for thermoforming, it
attains full tensile strength and is very strong tough film. Film of
less than 3 mil will be too thin and
will break especially during more
severe forming. Thickness of
2930 film will depend on upon
you part ,process. |
|
| |
|
|
| |
Note: It is critical
to achieve correct dry film
thickness for removal and peeling. |
|
| |
 Curing: |
It is possible to get a 3 mil
tack free dry coating film in
less than one hour drying in
air at ambient temperature.
For maximum tensile strength ,
12 hour drying time is better.
Blowing air past the surface of
the wet film, drying time can
be shortened. Heated air up to
temperature of 115f can also
help in drying time.
Plastic-Mask 2930 cures upon
water evaporation.
Dry
time is dependent upon
temperature, humidity, air
movement and thickness of the
coating. Curing may be
accelerated by forced dry air up
to 100 degrees Fahrenheit. Force
dry coatings can cure in less
than 10 minutes. Most coatings
without assist will dry in a few
hours. It is imperative that
Plastic-Mask 2930 be thoroughly
cured and dry, before an attempt
is made to peel the coating from
the substrate. Cured coating is
transparent throughout. Cured
Plastic-Mask 2930 is water
resistant. Surfaces coated with
Plastic-Mask 2930 can be water
mopped.
Application by
roller might require a few
coats. Thick coating peels in
one large continuous sheet. Thin
coatings will break in areas of
coating weakness. Plastic-Mask
2930 is water based for safe use
and easy water clean up. Dry
coatings are water resistant.
When applying Plastic-Mask 2930
use the same protection as used
while applying paint. |

to use Plastic-Mask 2930 on our
aircraft Wind screens.

Precautions: |
|
|
| |
The surface to be protected with
Plastic-Mask 2930 should be dry, clean
and free from oil, grease and other
water incompatible matter. The clean
surface helps even distribution of
Plastic-Mask
2930. The surface remains
clean when Plastic-Mask 2930 is removed
and surface clean up will not be
necessary for second time
application. |
|
|
|
|
| |
Patch Test: Always test a
small inconspicuous area first.
Because of various substrate
characteristics and conditions like
porosity, deterioration,
embattlement, adverse wear area,
type of ink, paint and or other
coatings applied, abrasion of panted
surfaces, and the like ,it is
difficult to predetermine specific
effects from this product. |
