DisCoat Optishield
DISCOAT OPTISHIELD is an aqueous based peelable coating designed for in-process as well as archiving protection of optical media. Suitable for CD, CD-R, and DVD formats.
DISCOAT OPTISHIELD provides a durable, long lasting
protective layer that protects against surface scratches and oxidation. The OPTISHIELD
film releases easily and cleanly from the protected substrate, requiring no tools,
solvents or additional cleaning after peeling.
OPTISHIELD is applied directly to the stamper surface by spin coating. Because the product is aqueous based, it may be applied to water wet substrates after electroforming, providing immediate protection from oxidation. Once applied, the film dries from an opaque white color to a clear coating so that there is no guessing when the film has completed drying. During this curing process, OPTISHIELD uses capillary action to remove all water form the metal substrate, elimination under-coating oxidation.
OPTISHIELD'S film durability, dry time and ease at removal are comparable to traditional vinyl films. Like solvent-based products, surface contaminants are removed with the film upon peeling.
OPTISHIELD contains no solvents or other hazardous or toxic materials, allowing for zero VOX** operation in stamper finishing. Furthermore, the peeled OPTISHIELD film is also non-hazardous, requiring no special handling.
The dried OPTISHIELD is so soluble in mild alkaline solutions, making spin coat bowl cleaning easy and simple.
THE OPTISHIELD ADVANTAGE:
* Easy spin coat application
* May be applied directly to water wet subtrates
* Eliminates under coating oxidation
* Durability, drying time and release comparable to traditional vinyl fimls
* Suitable for in-process and archival protection on all optical media formats
* Completely non-toxic, non-hazardous formulation; contains zero VOX's
* Easy clean-up
