Teflon is a household name that commonly invokes images of eggs sizzling on a skillet, spatulas flipping pancakes, or rice steaming in a pan.
But, there is much more to this magical non-stick coating.
Teflon, a brand name for PTFE (polytetrafluoroethylene), prohibits food from sticking to pots and pans because of its hydrophobic properties.
As a low-energy, fluorocarbon solid neither water nor water containing substances can influence the surface. This means that nothing will stick to the surface or penetrate it.
Today, Teflon has improved culinary pursuits and made cooking more accessible, but that isn’t the only field PTFE has influenced.
The medical device industry would not be what it is today without PTFE. As medical devices work intimately with the human body, they must be completely sanitary, inert, and harmless.
With its lubriciousness and impenetrable properties, PTFE is used to coat a variety of medical devices such as catheters, surgical equipment, balloons, bladders, and implants.
But, PTFE only works when the coating itself sticks to the surface. This requires proper surface preparation which can be challenging in any manufacturing floor. It’s especially difficult in medical device manufacturing as specifications are so high and there is no room for failure. …Read More
Plastics manufacturers are all too familiar with the challenges of bonding thermoplastics. Last week, BTG Labs successfully hosted a webinar with Plastics Technology to discuss improving bonding of thermoplastics. The webinar, entitled “Understanding Surface Energy: How to Measure and Control the Surface Properties of Thermoplastics to Maximize Adhesion,” brought in almost 400 registrants.
Presented byBTG Labs’ Chief Scientist Dr. Giles Dillingham who discussed the surface characteristics of thermoplastics. Dr. Dillingham also explored surface treatment processes such as flame, corona, and plasma, and ways to monitor and verify those processes. The ability to understand and measure the surface precisely is the key to successfully bonding thermoplastics.
Every plastics manufacturer knows that bonding low energy thermoplastics can be challenging. In the upcoming webinar hosted by Plastics Technology, BTG Labs’ Chief Scientist Dr. Giles Dillingham will discuss practical ways to improve bonding of thermoplastics more reliably and efficiently.
Dr. Dillingham will discuss the nature of thermoplastic surfaces and how the manipulation of various surface treatment processes—flame, corona, and plasma—make or break a surface. The webinar will discuss how the Surface Analyst uses water contact angle measurements to lend imperative insight into surface energy and in turn, hone in on the necessary treatment level for a higher quality, more consistent manufacturing process. After all, the most expensive surface treatment is nothing without an in-place monitoring process. …Read More
Manufacturers often encounter a similar puzzle, when cleaning invisible contaminants from a surface, how do you know when the surface is clean; how clean is clean enough? This is a common question that manufacturers ask when preparing their surfaces for bonding, coating, sealing, printing or painting. Until now, there hasn’t been an objective and reliable way to answer this question. Successfully cleaning a surface directly correlates to the adhesive ability of the surface. In order to get something to stick reliably the surface must be clean. How we define that parameter is different for a variety of materials.
For example, you clean your car differently than you clean your dishes. Why? Because a car rides on the road through rain, smog, dirt, maybe mud, and the other is a vehicle for your food.
At BTG Labs, our answer to the “clean enough” question is, “Depends on what you’re doing.” There are dozens of critical surface preparation processes that exist for a number of different applications. A handful include:
- Flame treatment on polypropylene bumpers prior to painting
- Plasma treatment on PET catheters prior to coating
- Hand sanding and solvent wiping on aircraft nut plates before adhesively bonding to composite
- Grit-blasting titanium golf clubs in preparation of bonding to composite
- Corona treatment on film for packaging prior to metallization, lamination, or coating
Roosevelt University, a liberal arts college in the Loop of downtown Chicago perfectly contrasts antiquated and contemporary architecture. Roosevelt’s first venue, constructed in 1889 just in time for the World Fair, is 17 floors of beautiful Art Nouveau structure. The Auditorium Building encompasses ornate railings and scaffolding, topping off with a regal library and a lofty tower overlooking Grant Park. However, because of its age, the Auditorium Building demands constant attention and is inefficient in the frigid Chicago winters and hazy summers.
Their new building, the Wabash Building, erected in 2012 is just the opposite. Its 32 towering floors of curved glass superintends the Auditorium Building, arriving amongst the structural giants of Chicago. Illustrating the epitome of modern design, this highly efficient, state of the art structure is LEED certified.
When looking up at the two buildings, old charm vs new-age sleek, the phrase comes to mind: they just don’t make things like they used to. But, there’s necessity behind this. As the global population rises, infrastructure becomes denser, and resources become scarce, engineers concentrate on building smarter. Designing a building that spares no expense—in terms of efficiency in operation and manufacturing of these smarter materials—is pivotal. This all begins in the research and development lab and extends to the manufacturing floor. Materials and processes are developed to allow for more efficiency in both the production of materials and the final construction. Guaranteeing bonds will hold; paint, print, and coatings will stick; seals will persevere; and cleaning processes will clean effectively is crucial to manufacturing a product that will withstand stresses of any structure.
That is why more and more manufacturers are turning to the Surface Analyst™. This hand-held instrument ensures any surface is ready for effective bonding, coating, cleaning, sealing, printing, or painting. The ability to verify and quantify critical surface processes on the manufacturing floor is the keystone to efficient manufacturing and smarter structures.
A high-grade window manufacturer, for example, uses the Surface Analyst to verify plasma treatment on vinyl window frames prior to sealing. This guarantees the windows will efficiently heat or cool a structure while also withstanding the elements of rain, wind, and snow. …Read More
Manufacturers are all too familiar with the challenges of getting a bond to stick and hold. The success of a bond relies on the surface created prior to that bond, so, monitoring and measuring surface processes is the only way to know that the surface is ready to bond reliably.
BTG Labs’ President Tom McLean and Sales Engineer Lucas Dillingham presented during Plasmatreat’s Open House on the 4 Surface Fundamentals for Successful Bonding in Manufacturing. They presented to industry leaders who can easily relate to bonding and cleaning issues. The presentation was such a success that BTG Labs decided to turn it into a webinar.
Challenges with establishing a strong, reliable bond, when painting, coating, sealing, or printing are tied into the surface preparation process and the ability to monitor that process. This presentation focuses on the bond surface and what it takes to bond properly to that surface. There is also a comparison of various cleaning methods using contact angles taken with the Surface Analyst.
While other monitoring processes such as dyne and water break fail to provide quantitative insight, monitoring cleaning processes with the precise and quantitative Surface Analyst tells the user, objectively, whether the surface is properly prepared to hold a reliable bond. …Read More

Manufacturers working with metal and worrying about metal performance are all too familiar with the obstacles that come along with coating, painting, bonding, printing, or sealing it. While the uses of metal in manufacturing are countless and exist in numerous industries, the common denominator is ensuring the appropriate surface cleanliness prior to surface critical processes to guarantee successful adhesion. Common surface cleanliness gauges—dyne inks and water break—are subjective and do not offer quantitative results. Water break can be messy and time consuming and dyne is destructive to the part and dangerous to the user. While these methods can offer some insight into surface cleanliness, they are less than ideal.
BTG Labs Surface Analyst is a fast, easy, accurate, and non-destructive surface cleanliness gauge that tells the user right on the manufacturing floor how prepared the surface is to bond. This hand-held instrument improves surface processes and guarantees a bond will stick. Numerous manufacturers in industries such as consumer goods, automotive, and aerospace, have implemented the Surface Analyst in their specifications to improve their critical metal surface processes. …Read More
