Temporary Protective Peelable Coating For Silicon Wafers, Glass, Photomasks,Platter,Optical Media, Optical Disc, Application Introduction:
4210 is an easy to apply, strippable coating to protect substrates from scratching and marring during polishing, handling and storage. Can be applied by spinning or dipping. Will not leave a residue.
General Chemical's Disccoat 4210 is a CLEAR water resistant, Optical Media Protective Coating, peelable temporary protective coating which has many applications. It may also be used to protect various types of surfaces during industrial processing. Disccoat 4210 air-dries quickly, leaving a tough, yet flexible coating that is easily removed from a variety of surfaces.
4210 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 Disccoat 4210 film out-performs the dry plastic film. Applying no coating is cheap, but provides no protection. Disccoat 4210 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 4210 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.
Temporary Protective Peelable Coating For Silicon Wafers, Glass, Photomasks,Platter,Optical Media, Optical Disc, Application Application:
Optical Media Protective Coating Disccoat 4210 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. 4210 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.
Temporary Protective Peelable Coating For Silicon Wafers, Glass, Photomasks,Platter,Optical Media, Optical Disc, Application Curing:Floor protection, floor coating and temporary protective coating
4210 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 4210 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 4210 is completely cured.
Temporary Protective Peelable Coating For Silicon Wafers, Glass, Photomasks,Platter,Optical Media, Optical Disc, Application Storage:Floor protection, floor coating and temporary protective coating
4210 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.
