Panacol Vitralit® adhesives are one-component, solvent-free radiation-curing adhesives. The advantages are very short curing times, good adhesion to a variety of substrates, and easy handling. Vitralit® products are used in electronics, medical applications, optics and for fixing parts in general.
Vitralit® 4731 is a UV / Visible light curable material that is very flexible after cure. Vitralit® 4731 adheres to polyimide, PVC, ABS, and other plastics as well as dissimilar materials including glass, stainless steel, and epoxy boards. When properly cured, Vitralit® 4731 is clear, tack-free, and highly resistant to moisture and yellowing. Vitralit® 4731 demonstrates high tolerance to thermal cycling and is an excellent adhesive for strain relief. Vitralit® 4731 cures rapidly with broad spectrum UV lamps (320-450nm), as well as monochromatic LED systems. Recommended LED wavelengths for optimal curing are 365nm and 405nm. Vitralit® 4731 has passed the testing required for USP Class VI biocompatibility and ISO 10993-5 approval. Vitralit® 4731 is compatible with typical sterilization methods including gamma, ethylene oxide, and limited autoclave.
