  • Nestled in the tall pines of the Jemez Mountains lies the Los Alamos National Laboratory. This center of scientific excellence, brings together some of the top minds in the world to maintain the country’s nuclear arsenal.

    This maintenance requires precise attention to detail and includes upkeep and repairs.

    Dr. Dillingham presented to the lab last week on how those repairs can be improved and ways to establish the strongest possible bond.

    His presentation, “Understanding and Controlling the Bond Surface in Manufacturing for Reliable Adhesive Bonding” delved into surface characteristics, the importance of controlling the bond surface, and characteristics of the surface that can be manipulated to form stronger bonds. …Read More

  • Dr. Carlos Barrios, a colleague of mine from 3M St. Paul, asked over dinner at the last meeting of the Adhesion Society if I would like to take part in teaching a week-long course in polymers at the leading university in Colombia.

    The course took place at Universidad Nacional in Bogota, Colombia. About 50 engineering students and several professional engineers from the community attended.

    I taught the course in conjunction with Carlos and Omar Arias (Manager of Technical Service for 3M in Latin America).

    We split the course into three segments: I taught “Fundamentals of Surface Energy and Adhesion”; Carlos taught “Recent Advances in the Science of Pressure Sensitive Adhesives”; and Omar taught “3M Solutions through High Performance Pressure Sensitive Adhesives”.

    My segment of the class included hands-on experiments that demonstrated the relationships between surface energy and peel strength of pressure sensitive adhesives.

    The students were incredibly engaged; as a result, the class lasted for almost 11 hours. The questions were technically very advanced and indicated a wonderful level of interest.

    Bogota was a wonderful experience in itself.  Founded by the Spanish Conquistadores in 1538, the old part of the city looks and feels like a medieval Spanish city. …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.

    This table shows the relationship between low surface energy and relative interfacial toughness. While thermoplastics are highly durable, they cause difficulties in bonding because of their low surface energy.

  • 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

  • New Paper Presented at ANTEC 2017

    by Emily Walsh May 2017

    Last week, BTG Labs exhibited and presented at ANTEC 2017. We were pleased to connect and exchange intelligence with leaders in the plastics industry.

    Our booth featured the Surface Analyst, which uses contact angle to measure surface cleanliness of a material. This monitors the surface preparation process and ensures readiness to bond, print, paint, coat, or seal which can be challenging on plastics. More and more, plastics manufacturers are turning to the Surface Analyst for guaranteeing their surface treatment and final product.

    Along with exhibiting, BTG Labs’ Chief Scientist Dr. Giles Dillingham presented the paper, “Rapid Evaluation of Surface Properties of Medical Tubing for Process Development and Quality Assurance.” The paper explains that the key to manufacturing high performance medical devices is understanding and controlling surface properties. Crucial characteristics of medical tubing such as wettability, adhesion, antithrombogenicity, and biocompatibility depend on only the top few molecular layers of a surface. Dr. Dillingham discusses research done with the Surface Analyst for highly sensitive surface measurements on medical tubing to control coating application. …Read More

  • Visit booth 220 or attend the presentation of Chief Scientist, Dr. Giles Dillingham.

    What is known as The Plastics Technology Conference, ANTEC (Annual Technical Conference) 2017 brings together diverse members of the plastics industry from around the world. Taking place in Anaheim, California May 8-10, ANTEC 2017 showcases the latest technologies and advancements in the plastics industry.

    Dr. Dillingham’s presentation, “Rapid Evaluation of Surface Properties of Medical Tubing for Process Development and Quality Assurance” explores methods of quality assurance testing on sensitive medical tubing. Significant properties of medical tubing–adhesion, wettability, antithrombogenicity, biocompatibility—allow for the ability to deliver fluids, gases, drain, and enter the body effectively. Yet, these properties depend on the top 2-3 molecular layers of the tube’s surface. This is why precise control of the surface is crucial for the success of medical tubing. But, this can be challenging. Laboratory techniques such a FTIR and XPS can reveal surface composition, however, these methods are not practical on the manufacturing floor.

  • 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
