3Dresyn HTR-Silicone1 has these features and benefits:
High Temperature Resistant Silicone above 200ºC
UV & EB curable silicone soft and elastic photopolymer for nano and micro fabrication (photolithography and softlithography), such as printing of soft and elastic stamps for Nano Imprinting lithography NIL and for soft & elastic negative photoresists for standard UV lithography & PCB technology processing, UV patterning of core and cladding
UV curable: excellent photoreactivity at 250-410 nm with medium energy dosage
Electron beam EB curable
compatible and blendable with our 3Dresyns for nano & micro fabrication
100% foldable without breaking
synthetic resin source

100% organic (free of inorganic materials)
contains hydroxyl groups for bonding release agents, such as perfluorodecyltrichlorosilane (FDTS)
no thermal treatment is required
easy processing with standard lithography equipment
easy removal of uncured resin with ketones, alcohols and esters
Applications
UV curable molds for soft lithography
LED lighting encapsulation
power supplies
sensors
connectors
transformers
amplifiers
