Master Bond Application Highlight

The Application

A customer is working on a medical device which requires bonding of an optical lens using a one component system. The device could be disposable or reusable with the possibility of sterilization cycles.

Finding the Answers

  • What are the substrates, their dimensions, and the bonding area?
  • Does the adhesive have to be biocompatible?
  • What would be the sterilization procedure used, and what is the frequency of sterilization?
  • Does the adhesive have to be optically clear?
  • What is the preferred viscosity? How would the adhesive be applied/dispensed?

The Solution

Master Bond offers a variety of USP Class VI approved UV curable compounds

Making certain assumptions including the assumption that the bonding area is completely accessible to UV light, we can recommend UV10Med or UV10TKMed.

Both products are optically clear, and they meet the USP class VI specifications. In addition, UV10TKMed also meets the ISO 10993-5 specifications.

UV10Med offers very low viscosity in comparison to UV10TKMed, which offers moderate (yet flowable) viscosity.

Both products can be used in applications involving sterilizations such as ethylene oxide and gamma radiation. The potential for UV10TKMed extends its usage even in applications involving repeated sterilization procedures such as autoclaving/steam sterilization, not common for most UV curing adhesives.

Additional Products

In certain applications where specifically meeting biocompatible standards is not critical, some other products which can be used are: UV10, UV10TK40, and UV10TKLO-2.
