3Dresyn NMF PDMS-like A30 Bio, Biocompatible very soft silicone like photopolymer with Shore A30 for nano and micro fabrication

Product description

3Dresyn NMF PDMS-like A30 Bio is a UV & EB curable organic soft and elastic photopolymer for nano and micro fabrication, including photolithography and soft lithography, printing of soft and elastic stamps for Nano Imprinting Lithography NIL, and soft & elastic negative photoresists for standard UV lithography, PCB technology processing, and UV patterning of core and cladding.

This resin exhibits properties similar to silicone elastomers PDMS, but with increased tear and mechanical resistance.
