Medical Device Company Turns to PMF Adhesives

When a large company, such as a defense contractor, acquires a small manufacturing contractor, they inherit the manufacturer’s processes – for example, in-house mixing of adhesive systems.

The small manufacturer may not have good procedures in place for mixing adhesive systems or testing protocols to determine performance characteristics.

A medical device company faced such a challenge. After acquiring a smaller contractor, the medical device manufacturer learned that the contractor had been mixing five adhesive formulations in-house using up to six ingredients for each formulation. The precise blending of these ingredients was critical to the proper functioning of the medical device.


The company called on Appli-Tec to perform the following:

  • Mix the ingredients to the proper mix ratio
  • Test each formulation for:
    • Pot life
    • Viscosity
    • Hardness
    • Glass transition temperature (Tg)
    • Heat of reaction
    • Lap shear strength
  • Degas, freeze and ship the products

Appli-Tec also set the upper and lower control points on each test, which gave the medical device manufacturer assurance that the precision-mixed, degassed, and frozen formulations being shipped were fully tested and met exacting specifications.


Appli-Tec now manufactures and ships the company’s PMF products – allowing the manufacturer to eliminate in-house mixing and potential product failure.

Meticulously processed to exact specifications, Appli-Tec’s precision mixed and frozen (PMF) adhesives guarantee consistent results. Rigorous testing ensures every batch of material performs the same.

When ready to use, customers simply remove a syringe from the freezer, wait 10 – 30 minutes (depending on syringe size) for the syringe to thaw, then use. The material is as good as if it were mixed minutes prior.
