Functional performance characteristics

• Ideal 2PP biocompatible photocurable resin negative photoresist for high precision additive manufacturing of ultra rigid high aspect ratio 3D nano & microstructures with ultra high deflection temperature
• Excellent balance of resolution shape accuracy and writing speed
• Photoreactive from 200 to 410 nm with Fine Tuner 2PP FT8 Bio single 1 photon absorption
• Photoreactive from 600 to 810 nm with Fine Tuner 2PP FT8 Bio two photon absorption
• Ultra rigid
• Good adhesion on glass and other substrates
• Clear, non yellowing
• Durable

Processing and handling performance

• Designed for Dip-in two-photon lithography DTPL also referred as Dip-in Laser Lithography DiLL where the 2PP resin is immersed upside down in the microscope objective
• Designed for conventional 2PP systems also refered as Two Photon Lithography TPL where the 2PP resin is positioned upright on the substrate
• Easy handling by direct drop casting
• Printable by most commercial two photon polymerization printers with wavelengths from 600 nm to 800 nm
• Supplied at different writing speeds: fast, intermediate, slow, and non reactive for custom control of writing speed and resolution
• Tunable with the free sampled Fine Tuner 2PP FT8 Bio for custom adjustment of writing speed
• Tunable with the free sampled Fine Tuner 2PP LB3 Bio for maximum resolution with submicron feature sizes
• Supplied in a relatively low and high viscosity version
• Choose a LV low viscosity version (<1000 mPas) for easy development or cleaning of uncured resin with conventional 2PP upright configurations
• Choose a HV high viscosity version (>2000 mPas) for upside down DiLL configurations
• Easy removal of uncured resin with conventional developers such as isopropanol IPA and propylene glycol methyl ether acetate PGMEA
• Ideally use our biocompatible Cleaning Fluid UNW1 Bio to preserve transparency, prevent whitening and chemical attack of IPA and conventional alcohols

Chemical and safety characteristics

• Biocompatible
• Safe and biocompatible, compliant with the Quality requirements of FDA, ISO 20795, 13485 & 10993
• Synthetic
• Hydrophobic
• Organo-tin free
