Techsil outlines its new UV curing adhesives for medical device assembly

Techsil has launched three new products for the medical device market. The adhesives from manufacturers Panacol includes Vitralit 7562, a moisture-resistant adhesive which maintains high adhesion after a seven day water immersion. Other introductions are epoxy adhesive Vitralit 1655 and acrylate Vitralit 4731, expanding Techsil's portfolio of PVC and polycarbonate adhesives. Both products are said to be flexible and therefore ideal for bonding larger surfaces without inducing stress cracking. All adhesives are specifically formulated to meet USP Class VI and/or ISO 10993 biocompatibility standards and are  solvent free.

These engineered adhesives can be cured within seconds with UV LED equipment: New tests have shown that in many applications it takes only seconds until the adhesives are fully cured using Hönle's LED Powerline, featuring a high intensity at a wavelength of 405 nm. With this technology, medical devices can be assembled quickly but also bonded with an optimum precision and reliability. Therefore, the adhesives are perfect for applications such as needle bonding, assembling polycarbonate housings from dialysis filters or blood oxygenators, and joining flexible tubing to plastic connectors. The bonded joints ensure utmost stability and resist high extraction forces. This high strength is maintained after undergoing several sterilisation cycles. Panacol’s fast-curing adhesives for disposable medical devices can be assembled quickly and safely while keeping production costs low.
