Addison Clear Wave’s PFAS-free Epoxy Working Stamp Resins

Addison Clear Wave has released two new PFAS-free epoxy working stamp resins for UV lens molding and similar applications.  Working stamps can be cast on glass backplanes from metal master molds using a conventional anti-stick material.  The working stamps thus made have high water contact angles and can be used with standard imprint resins without applying an anti-stick layer in the imprint step.

WS-101 and WS-102 resins give tough working stamps with Young’s moduli similar to that of polycarbonate.  The toughness and Tg’s >100 °C ensure that the stamps will not distort in the imprint step, but the stamps are flexible and readily release from imprints even when no anti-stick layer is used in the imprint step.
