  • A Beer with Giles Dillingham

    by Emily Walsh April 2017

    In 1987, Giles earned his PhD and moved to Midland, Michigan to begin laboratory work at Dow Chemical.

    The office of Giles Dillingham is unique, eclectic, and full of resources; very much like Giles Dillingham. The corner office is filled with books, antique tools, paintings by his beloved wife, family photos, and of course, a very nice stereo set-up.

    Giles, BTG Labs’ Founder and Chief Scientist, can often be found typing eagerly away at a report while listening to classical music, or seated at the Cherrywood table, collaborating with colleagues.

    One Friday evening, as the Cincinnati sun began to sink, I shared an end of the week beer with Giles in his lovely office to hear the origin story of BTG.

    Emily: So, Giles, you started BTG Labs. Where did it begin?

    Giles: Well, after I finished my PhD at the University of Cincinnati, I had a job waiting for me at Dow Chemical up in Midland, Michigan. And, I worked there for five years in a variety of assignments, mostly in polymer processing and surface properties. Central Research at Dow in the 90’s was an amazing place to work.  It was a very academic environment with amazing scientists from all fields. I spent most of my time in the laboratory. I learned and grew a whole lot.

    E: And, then what? …Read More

  • BTG Labs is gearing up for Earth Day; after all, we proudly manufacture an instrument that is valuable in a variety of industries from aerospace, automotive, packaging, and even renewable energy. It’s also pretty eco-friendly.

    The Surface Analyst™ improves the manufacture of renewable energy equipment including solar panels, wind turbines, and electric cars. BTG Labs also works with start-up companies creating brand new technologies for renewable energy. The Surface Analyst measures water contact angle to ensure that surfaces are ready to bond and withstand environmental stresses without failing. Its precision, portability, and ease-of-use allows for its implementation on the manufacturing floor as well as in the field for repairs and maintenance.

    Technicians use it for repairs on wind turbines in the field; solar panel manufacturers value its precision when bonding dissimilar materials to withstand weathering; and electric car companies use it to guarantee paints, bonds, seals, and coatings will stick reliably. New applications for improving renewable energy manufacturing using the Surface Analyst reveal themselves constantly.

    Cleaner Manufacturing 

     

    The Surface Analyst also contributes to conservation in every manufacturing field. Because it offers manufacturers precision and is non-destructive, it cuts down significantly on waste material. The Surface Analyst replaces dyne inks which hold harsh chemicals—including teratogenic chemicals—that are hazardous to the user and the environment. Because of this, dyne cannot be used to test on the actual material and often requires a coupon of the material that has been cut off or specifically designated for testing, off the assembly line. Dyne is also highly subjective and leads to inconsistencies in manufacturing, causing rework and failures, which in turn, means more waste. On the other hand, the Surface Analyst uses highly purified water so it’s completely harmless to both the user, the part, and the environment. A win for both the manufacturer and the planet. …Read More

    The New BTG Labs

     

    2016 was a big year for BTG Labs. The year brought new members and growth, to improvements on the Surface Analyst and a new company look. The BTG Labs team comprises of a collection of members from diverse backgrounds such as engineering, marketing, software development, and sales.

    Our new branding took us from Brighton Technologies Group, to BTG Labs. Our new name and logo better reflects who we are: a modern and innovative Surface Analysis company. We call the new, full color logo the Taking Flight mark. It is an abstraction of the contact angle measurement, flowing across multiple dimensions. The logo celebrates the uniqueness and innovation of BTG Labs as well as our ties to diverse industries. Along with these improvements have come improvements to our facility with a new exterior paint color and completely re-done interior. We now have a space that reflects our new look and feel.

    BTG Labs has evolved from an R&D services group to a booming Surface Analyst product company. Through years of deep experience and knowledge in surface engineering and material science, we decided to offer this knowledge to our customers in a standard package and in 2016, created new standard Process Development Packages. These new packages help companies to develop and control their manufacturing processes. Once these processes are established, the Surface Analyst monitors them.

  • BTG Labs Celebrates Knowledge

    by Emily Walsh December 2016

    Monthly Lunch & Learn

    As a science based company, BTG Labs emphasizes the importance of continually sharing and gaining knowledge. Once a month, the office gathers together over lunch for one reason: to learn.

    Our topics vary, as do our “instructors”. We’ve had Lunch & Learns presented by a chemist about our X-ray Photoelectron Spectrometer, a “How the Surface Analyst Works” talk by a product engineer, and our most recent one, “Advancing and Receding Contact Angles” by our very own Chief Scientist and CEO Dr. Giles Dillingham.

    Lunch & Learn

    Dr. Giles Dillingham leading a Lunch & Learn.

    In our latest Lunch & Learn, Giles Dillingham, discussed advancing and receding contact angles. A common question among customers and even employees, concerns receding and advancing contact angles. The receding contact angle is a very sensitive measurement of surface activity and is used by many companies such as 3M to monitor surface treatment level. These contact angles can be measured by using a syringe to slowly deposit or remove the liquid from a surface, which in addition to being slow, can be very difficult to do.

    However, instead of a syringe, BTG Labs’ Surface Analyst™ uses patented Ballistic Deposition to measure water contact angle. Ballistic Deposition, unlike a syringe, allows for measurements on various surfaces and at any angle. Interestingly enough, this measurement produces a contact angle similar to the receding angle which correlates well with adhesive ability. The presentation always includes a question and answer portion in which all members of the BTG Labs team can ask questions.

    BTG Labs brings together brilliant minds of several disciplines like chemistry, engineering, and marketing. We have things to teach each other and we are always looking to learn more. As our team continues to grow, so does our ability as a member of the Material Science community.

    Evolution of Aircraft Manufacturing: Moving Towards a Lighter Material

     

    In the early 2000s, the U.S. Airforce recruited BTG Labs to aid in the development of bonding technologies for composite materials to replace heavier aluminum and titanium in aircraft manufacturing. Carbon fiber composites provide lighter, stronger options for aircraft materials. But, to realize these advantages composites  must attach by bonding, not by mechanical fasteners. The primary obstacle to bonding has been the lack of a practical way to inspect a bond surface and ensure that they have been prepared in a way that will produce a strong, reliable bond. Thus, they needed a method to adhere the composites effectively, efficiently, and confidently. …Read More
