Isosport ICP 8210 PA / polyamide / Nylon topsheet.
The best and toughest topsheet available on the market.
Sanded , flamed or both.
Suitable for sublimation:
Recommended max. 160 degrees and time cycle of about 2min or so. Allow also good cooling time!
I personally did 140C for about 4min. cooling 5min. Vacuum press, but read more here before you try first time!
Topsheet that is flamed only might weaken the bound after sublimation, so make sure you do it for minimum time and temperature possible in order to keep the good bound to epoxy. Do tests first. Sanded version is bit less sensitive to this. After the cooling it is good idea to flame treat the base/topsheet (PA nylon) to improve adhesion to epoxy.
And general all ICP 8210 transparent materials are recommended to be sublimated on the BACKSIDE.
This is the advantage of those transparent films that you can do the designing from the backside and the color is protected through all the foil thickness.
Nevertheless also the topside of the material can be sublimated if you have any need to sublimate from the topside. Or you prefer the look of it if you sublimate from the topside.
Sublimation will affect the bounding to epoxy. Since the grinded side will be less affected and present better bounding values, it is recommended to use the grinded side as epoxy side. If topsheet is not grinded, only flamed, do testing and find minimum sublimation time at the temperature! Best graphics results of sublimation are on the smooth glossy side.
PS: Please before using check if your topsheet has protective film on the outside. We try as ofen as we can to get topsheet with protective film.
this picture is glossy version. When pressed with epoxy it will turn totally clear!
