Introduction:
Protective Black Peelable
Coating For Optical Media,
Optical Disc Liquid Masking Film |
|
|
|
|
|
| |
4710 is an easy to apply, strippable coating to protect substrates from scratching and marring during polishing, handling and storage. Can be applied by spinning ,dipping or spray. It will not leave a residue. |
|
|
|
|
| |
General Chemical's Stripcoat 4710 Black is excellent hiding black color, water resistant, Optical Media Protective Coating, temporary protective Peelable coating which has many applications. It may also be used to protect various types of surfaces during industrial processing. Stripcoat 4710 Black air-dries quickly, leaving a tough, yet flexible coating that is easily removed from a variety of surfaces. |
|
|
|
|
| |
4710 represents the ultimate in solvent-based removable coating technology. It is stabilized against brittleness and is not softened or penetrated by most water-based compounds. |
|
|
|
|
| |
The two challenges that we have are non-standardized coating processes and material costs. Even though optical disc masking is guided by very rigid specifications, each facility may have its own method of protecting the finished product. Some plants do nothing other than store the nickel stampers in a plastic CD-type acrylic box, while others coat with either a Peelable vinyl resin or dry plastic film. For those using spin-coated vinyl films, there is no standardization for process cycles (like spin-coat speed, time, etc.) and processes may vary between equipment manufacturers, let alone in-house built machines. |
|
|
|
|
| |
The Stripcoat 4710 Black film out-performs the dry plastic film. Applying no coating is cheap, but provides no protection. Stripcoat 4710 Black has some real performance advantages, especially its ability to remove water-stains and moisture related defects. Moisture related defects, as measured by loss of electrical signal read-back of nickel electroforms, is reduced by 50%. This is significant since an optical nickel electroform cost between $50-75 to produce. A single application of 4710 at one of the world’s largest manufacturing facility, the world's largest replicator of compact audio discs), restored environmentally damaged (oxidation) nickel stampers, cutting electrical signal loss in half. |

 :I
am looking for a protective coating
I can brush on a polished surface to
protect it during manufacturing. It
seems that a customer with similar
needs used Stripcoat 4710 with good
results. Can you send me pricing for
a small sample of this product for
us to evaluate? I would also like to
know the volume price in case we see
good results.
2.
we
are manufacturer of Imaging
Plate systems which are used as
a replacement of conventional
film. A very important field is
the turbine blade inspection. In
turbine blade inspection,
sometimes, the films/imaging
plates need to be of a special
shape and therefor need to be
cut. With film, as it is a
single use item, you just cut
the film to the designated
size/shape and re-pack so that
it is protected from being
exposed by light.
Imaging plates are almost as
thin as film but can be used a
couple of hundred times, if
handled with care. They are
light sensitive as well, but in
opposite to the film, IPs can be
erased by light. So we have to
protect them from losing the
information while unpacking them
after the exposure took place.
The product I am looking for
shall come with the following
features:
1.
It shall be free of water, since
water damages the protective
layer on the IP
2.
It shall be a "spray on" or
"paint on" solution
3.
It shall be very easy to peel
of.
5.
It shall be free of any
dangerous ingredients - and
shall not require any protective
gear such as mask and so forth
6.
If possible, it should not be
"dangerous good" and thus easily
transportable by aircraft.

Application:
Protective Black Peelable
Coating For Optical Media,
Optical Disc Liquid Masking Film |
|
|
|
|
|
| |
Optical Media Protective Coating Stripcoat 4710 Black should be used as received. It is applied by airless spray, spinning, roll coating, or dipping. The sprayed coating dries to touch in 10 minutes or less, depending on temperature and film thickness. 4710 should be applied to form a dry film in the range of 1 to 3 mil (.001" to .003") thick. Application temperature is ambient to no lower than 50 F, as drying times will be affected. |
|
|
|
|
| |
Spin coating: apply coating to center of substrate (quantity determined by size of area to be coated). Use a minimum of 300 RPM for approximately one minute to achieve one mil dry film thickness. Lower spinning speeds will require longer (in excess of 10 minutes) drying time. |
|
|
|
|
|
|
|
|
|
|
| |
 |
Curing: |
|
|
|
|
|
| |
4710 will cure tack-free within 10 minutes after application. This is dependent upon temperature, humidity and thickness of coating. Deviations from application section will require adjustments in the curing times, as well as in the strip ability parameters. |
|
|
|
|
| |
Curing may be accelerated by forced drying at 110 degrees Fahrenheit for 3 to 7 minutes. |
|
|
|
|
| |
It is imperative that 4710 be thoroughly cured and dry, with no solvent odor being emitted before an attempt is made to strip the coating from the substrate. Substrates should not be stored in airtight containers until the 4710 is completely cured. |
|
|
|
|
|
|
|
|
|
|
| |
 |
Storage: |
|
|
|
|
|
| |
4710 should be stored in the original shipping container with temperatures between 60 and 90 degrees F, in an explosion proof environment. Containers should be sealed until needed. Protection from freezing is necessary. |
|
|
|
|
|
|
|
|
|
|
| |
 |
Removal: |
|
|
|
|
|
| |
4710 is readily removed from surfaces by peeling. |

|
|
|
|
|
| |
1.When applying, use the same protection as used while applying paint. Ventilation systems should be operating while the material is being sprayed.
|
|
|
|
|
| |
2.Chemical goggles, impervious gloves and respirators should be worn when handling 4710. |
|
|
|
|
| |
3.The use of non-sparking equipment is advised when applying or removing Stripcoat 4710 Black |

|
|
|
|
| |
I. Pre-cleaning of equipment: |
|
|
|
|
| |
To clean the pressure pot, airless equipment, spray guns, or spray lines do the following: |
|
|
|
|
| |
|
Flush equipment and lines with a paint thinner type material (ex. toluene, xylene or mek). |
|
Spray equipment is now ready for use with 4710. |
|
To clean equipment, thoroughly flush with the above type solvents. |
