We are making microchannels by machining in Plexiglas (PMMA). We want to cover the same with Pressure sensitive adhesive tape (PSA tape) to close the channels to improve turnaround time of our prototyping stage.
The PSA tapes are usually acrylate adhesive on a backing of some other polymer. We would then conduct some surface reaction utilizing the surface chemistry of PMMA.
We are not sure that if we use PSA tape, if we could perform reaction on the tape side of the channel or not.
Please let me know if anyone has done so?
P.S. we are using microparticles, and are not sure if they would stick to the tape due to the adhesive or the chemistry.
Hello Rohan,
You should cut the PSA to match the channels in the PMMA. it is going to be different, specially if you used a solvent to clean your channel.

Ahmed
