Medical Device Company Turns to PMF Adhesives

When companies, such as a defense contractor, acquire smaller contractors, they inherit the contractors’ processes – including in-house mixing of adhesive systems. Unfortunately, the smaller contractor may not have controls in place for mixing adhesive systems nor any testing protocols to determine performance characteristics.

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