News + Science from the Engineers of the Surface Analyst
Ever wonder what a hungry BTG Process Engineer is pondering while preparing the turkey for the feast of gratitude to be shared around the Thanksgiving table? The sharp minds at BTG Labs are ever vigilant in the quest for a surface state properly prepared for the task at hand; whether that be parylene conformal coating, interfacial bonding of composites, catheter coating, or turkey roasting. For the application (turkey) to be a success (taste good) there are Critical Control Points that must be closely monitored throughout the process (roasting up the bird).
What is a Critical Control Point?
A Critical Control Point (CCP) is any point in the manufacturing process where the surface condition of a material has the opportunity to change—intentionally or unintentionally—and impact adhesion, in a positive or negative way.
Why should you care about them?
This article was co-written by Elizabeth Kidd, BTG Labs’ Custom Applications Scientist and Research and Development Chemist.
Coating and adhesive bonding are extremely common manufacturing process steps. It may seem obvious, but to ensure success in these applications, surfaces must be properly cleaned or manufacturers run the risk of bonding and coating failures. Simple enough, but if that’s all there is to it then why do failures in these applications still occur?
What does it actually mean to have a clean surface?
The wait is finally over. Making its world debut at MD&M in Minneapolis, the Surface Analyst XA integrates the power, simplicity and ease of our handheld Surface Analyst directly into the manufacturing process. Now, the most precise surface monitoring technology will seamlessly unify with any production line, magnifying the speed and efficiency of surface quality control.
Autumnal vibes have landed at BTG Labs and along with football-watching, apple-picking, Halloween costume-planning we have an array of opportunities for you to interact with us and learn more about the Surface Analyst.
In the diverse and ever-growing world of medical devices, particularly those involving polymeric tubing, it is always crucial, and not always easy, to test and definitively guarantee the adhesion of your bonds and coatings. In the pursuit of bringing solutions to adhesion issues, BTG Labs is proud to be participating in the third annual AMI Medical Tubing Conference where our Custom Applications Scientist and Research and Development Chemist, Elizabeth Kidd, will be presenting the paper “UTILIZING WATER CONTACT ANGLE MEASUREMENTS TO VALIDATE CHANGES IN POLYMERIC TUBING SURFACE CHEMISTRY” on Tuesday, October 2.
Understanding and measuring the surface energy of your device is crucial to ensuring long lasting adhesion. This presentation will walk attendees through:
Partnering with Plastics Technology, BTG Labs held a webinar about a topic that’s attracting a lot of attention.
In the webinar you’ll learn about how blooming can be detrimental to adhesion when bonding, coating, painting and sealing and, in the cases of medical equipment failures, can be a tremendous risk. Dr. Giles Dillingham walks through strategies for detecting, controlling, and avoiding issues associated with blooming using methods like contact angle measurement.

Think about your company’s manufacturing operation.
Now, think about fixing your adhesion problems simply by knowing a single number…
What do both of these statements about surface adhesion have in common?
- “We need to measure surface quality of the teeth on a gear to make sure the coating stays on.”
- “We need to make sure the coating on our tubing is uniform, but we can’t measure a curved surface with our current surface testing method.”
