UV Adhesive for Difficult to Bond Plastics
Techsil has added a new adhesive to its Vitralit UV 4050s series. Vitralit UV 4050 MV features medium viscosity and is well suited for bonding plastics, especially for medtech applications and medical device assembly. With 450 to 650 mPas Vitralit UV 4050 MV is of medium viscosity.
When cured it shows a very good flexibility and an excellent stability. This transparent adhesive has a very low shrinkage of only 2%.
The newly developed adhesive provides excellent adhesion to most plastics like PVC, ABS, SAN and PC, as well as to stainless steel and glass. If at least one assembly material is transparent, Vitralit UV 4050 MV will cure very quickly to produce a strong and reliable bond. UV blocked materials like polycarbonate can be cured thanks to the adhesive’s ability to cure with visible light (>400nm).
Vitralit UV 4050 MV cures in seconds with UV-A and visible light. Both gas discharge lamps and LEDs are suitable to use for curing. Excellent curing results have been achieved with LED lights with a wavelength of 405 nm. Vitralit UV 4050 MV is currently being tested according to USP Class VI and DIN ISO 10993-4/-5 standards for use in medical applications. Vitralit UV 4050 MV is manufactured by Panacol, Techsil’s UV adhesives partner.
