Description

Vitralit® 1703 is a medical grade, plastic bonding UV adhesive where high gap filling capabilities are required. The thixotropic nature provides clean, fast and automated dispensing processes. It shows high material strength and a tack-free finish because of low oxygen inhibition.  Vitralit® 1703 has met the requirements for USP Class VI and is compatible with the most common sterilization methods like ethylene oxide and gamma sterilization. Therefore the product is suitable for use in the assembly of disposable medical devices or short term medical devices.  Vitralit® 1703 provides fast cure properties at low intensities. As a distributor in the UK for the world leading UV light systems manufacturer Honle, we can recommend using either a standard high pressure UV light or a UV LED light system which complement our adhesive technology. Vitralit® 1703 is a high viscosity, thixotropic and UV curing adhesive. Cured material appears translucent in thick layers but in thin layers it is transparent. Material thickness of 0.5 mm can be cured in approximately 10 seconds using UV light with intensity of 60 mW/cm². To obtain full cure at least one substrate must be transparent to UV light. The curing speed will depend upon the light intensity, light source, the exposure time, and the light transmittance of the substrate. Using wavelength of 405 nm high light intensities are required. Increased cure properties are developed after 12 hours.
