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.
