Description
LED405Med is a one part, nano-silica filled system that cures upon exposure to a 405 nm LED light. It meets ISO 10993-5 cytotoxicity requirements for use in medical device assembly. The nanosilica filler results in both lower shrinkage upon cure, as well as greater dimensional stability with a coefficient of thermal expansion of 35-40 in/in x 10-6/°C. It provides good toughness, is optically clear with a refractive index of 1.50, and offers excellent light transmission properties. The system can be used for bonding, sealing, coating and small encapsulations involving optical assemblies or other sensitive components.
