Dear all,

Do you have experience with soft PDMS mold?

Severe waveness exists on the surface of my PDMS mold. I tried to
eliminate this phenomena by decreasing curing temperature from 120
degree to 80 degree. But the wrinkling of PDMS still exits.
What is the possible reason? Surface tension of PDMS stamp? The
influence of anti-stick layer or the improper treatment of molding process?

If you have any suggestions, please feel free to contact me.

Thank you very much!

Sincerely,
