Medical Packaging Corporation (MPC) is using Loctite 3311, an off-the-shelf, medically approved light-curing adhesive from Henkel, to manufacture its Snap Swab product.

The Snap Swab comprises a Dacron swab tip on a polystyrene shaft encased in a polyethylene tube and was developed as an alternative to swab devices with glass ampoules, which were causing health and safety concerns.

When the shaft is broken, it releases the reagent and the swab is ready for use. With no glass to puncture the skin or prevent the reagent from flowing, it is quick and easy to use.

The swab had to be reliably bonded to the inside of the tube. In addition, the interface of the swab shaft, the protective tube and the reagent bulb had to be leak proof.

Henkel recommended Loctite Light Cure 3311 to bond both surfaces.

Key benefits of product application

  • Loctite 3311 is a one-component, low-viscosity adhesive that cures rapidly to form a flexible transparent bond when exposed to ultraviolet radiation and/or visible light sources.
  • The adhesive could be automatically dispensed directly on MPC’s existing equipment.
  • Frederic Nason, president of MPC, said: ‘The Loctite product made our Snap Swab reliable. It wouldn’t have been possible without it.’
