DOES THE LIGHT-ACTIVATED PLPP REAGENT ALWAYS HAVE TO BE USED WITH PRIMO?

The PLPP accelerates the degradation reaction of the anti-fouling polymer during photopatterning (a few seconds instead of a few hours). However, microfabrication manipulations with SU8 resins or NOA do not require the use of PLPP, since these products are photosensitive in the PRIMO wavelength (365 nm for the PRIMO 2 system, previously 375 nm).
