When a material begins its journey through a manufacturing process it becomes crucial to know and control everything that happens to that material as it makes its way down the line. There are two major factors to consider when understanding and controlling what happens to the surface of that material: the actual physical space of the warehouse and the time it takes to get through the entire process of being bonded, coated, painted, sealed, glued or printed. If you don’t know precisely what is occurring at each Critical Control Point and you don’t continually monitor the surface throughout the duration of the process, you could be trending towards adhesion failure and not even know it.
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?
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.”
“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?
In some industries–including film and flexible packaging–dyne is the primary language. BTG Labs’ Surface Analyst uses water contact angle measurements as a fast easy, objective, and non-destructive alternative to dyne inks.
The main concern we hear from manufacturers is that both the suppliers and the customers speak dyne as their standard.
The answer is the Surface Analyst’s Dyne Mode. This unique feature takes the Surface Analyst’s default contact angle measurement and automatically converts the measurement into a dyne/cm readout, directly on the instrument. This mode allows manufacturers to maintain their investment in the dyne measurement language.
BTG Labs believes in dyne measurements, but not dyne inks. Manufacturers using dyne inks struggle with inaccuracy and subjectivity, leaving much room for error. Furthermore, because of dyne inks’ destructive nature, users can’t measure on the actual part. This leaves dyne inks virtually impossible for testing the part on the factory floor. …Read More
Of all the challenges manufacturers face, creating and optimizing critical surface processes for various materials can be very difficult. Traits such as location, size, shape, and texture can add to the challenge. The success of any critical surface process requires an in-line, fast, easy, and accurate verification method.
That’s why more and more manufacturers are turning to the Surface Analyst. Whether it’s bonding, painting, printing, cleaning, coating, or sealing, BTG Labs’ Surface Analyst optimizes critical surface processes and monitors surface treatment on virtually any surface so the product is guaranteed to deliver.
BTG Labs engineered the Surface Analyst to adapt to any application directly on the factory floor. Patented Ballistic Deposition deposits a stream of micro-droplets on the surface; these micro-droplets contain kinetic energy which allows the drops to overcome various textures and different angles without interfering with measurement accuracy. The drop size can also be adjusted so that measurements can be taken on any sized surface from a giant wind turbine to a minuscule medical catheter.
