News + Science from the Engineers of 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.”
Adhesion failure in manufacturing is an opportunity in disguise for exceptional business growth…if you do the work to understand the why behind your failures.
“We need to be solvent wiping our aluminum before it’s coated/painted/sealed/insert adhesion-intensive process here.”
Technically, that’s correct…you should be.
But is that understanding enough?
What could happen in 10 minutes?
Well, if you work to improve a manufacturing operation, you know that means quite a bit…
Manufacturer’s who paint, print, bond, coat, or seal have been left in the dark when searching for answers to solving their adhesion problems but…
There’s a light at the end of the tunnel.
In our last blog post, we explained the most common mistake manufacturers still make when it comes to solving their adhesion problems in manufacturing.
To summarize this dilemma, we posed a question on our LinkedIn page that revisited one manufacturer’s struggle to solve peeling paint in their operation, but the main objective was to solve a common manufacturing problem, with a not-so-common solution…
Answer: If the manufacturers below had looked to the material surface itself to solve their surface adhesion problems, tens of thousands of dollars and hundreds of production hours could have been saved. But, how we do know that?
Water break testing. Dyne pens. Goniometer. No method at all.
The search for a reliable, repeatable, objective method (i.e. not based on opinion) for measuring surface readiness in manufacturing was a search all too common among our current customers, and these methods are the most commonly tried and (formerly) used among them.
Achieving great adhesion in manufacturing comes down to surface preparation (we call it “Clean to a Number”) and optimal surface prep is the difference between an average product…and an industry-leading one.
But getting there means having an objectively quantified understanding of the top 3 molecular layers of your material surface.
Did we just say “top 3 molecular layers?”
