3Dresyn NMF Glass-like1 Bio, Biocompatible rigid photopolymer for nano and micro fabrication

Product description

3Dresyn NMF Glass-like1 Bio is a UV & EB curable organic ultra hard and rigid photopolymer for nano and micro fabrication, including photolithography, printing of ultra hard and rigid stamps for Nano Imprinting Lithography NIL, hard and rigid negative photoresists for standard UV lithography and PCB technology processing, and UV patterning of core and cladding.

This resin exhibits properties similar to quartz glass. It is harder and more rigid than PMMA at room and high temperature, with higher temperature resistance without deflection than PMMA.
