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 working with metal 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

AMI Medical Tubing 2016
BTG Labs will host a booth and present at the Applied Marked Information (AMI) Medical Tubing Conference September 13-14, 2016. The event will take place in Crowne Plaza Boston-Woburn, Woburn, Massachusetts. This international event displays the latest in polymeric medical tubing and catheters, covering designs, materials, production and applications. The conference will host discussions on the latest standards and certification requirements. This field of medical device manufacturing is growing and evolving rapidly along with the use of polymers in medical tubing.
BTG Labs and the Surface Properties of Medical Tubing
BTG Labs will present on the sensitive and complex surface properties of medical tubing such as wettability, adhesion, antithrombogenicity, and biocompatibility. These properties depend on the chemical composition and structure of the uppermost 2-3 nanometers of the material. Thus, monitoring and managing these properties is crucial in manufacturing. This can be challenging as surface monitoring devices such as total reflectance infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS) can be impractical to employ on the manufacturing floor. BTG Labs will discuss the Surface Analyst™ and ways in which it can be utilized to monitor these minute surfaces accurately and sensitively on the factory floor. …Read More

conPolymers are some of the most common base materials used in automotive parts. Polypropelenes, Polyolefins, and ABS plastics are used in dashboards, door panels, bumper fascias, liftgates, sensors, and increasingly exterior doors and fenders. A polymer is a low surface energy material that typically needs some form of surface processing prior to bonding an assembly, encapsulating a sensor, painting an interior control knob or an exterior bumper fascia. These materials also tend to show high contamination with mold releases that can be tough to remove and will essentially guarantee unsuccessful adhesion or coating.
There are a variety of surface processing methods used in the industry to help remove contamination and increase the surface energy of these polymer materials. These processes include flame treatment, plasma treatment, corona treatment, and solvent wiping. Another option is to utilize specialty paints and adhesives that tolerate lower energy substrates. There are pitfalls, however, to implementing any of these methods that manufacturers need to be aware of. Understanding the nature of these surface-critical systems is the only way to guarantee success in the final result. Control of the inputs means predictability and control of the output.
