  • For the past five years BTG Labs has been a major presence at the annual meeting of the Adhesion Society. This year we are heading to Hilton Head, SC Friday 2/15 – Tuesday 2/19, to share our insight into how adhesion success begins and ends at the surface of materials used in bonding.

    BTG Labs’ CEO and Chief Scientist, Dr. Giles Dillingham, has been an active member of the Adhesion Society since the 1980’s and is a Robert L. Patrick Fellow of the Society. He has over 120 publications and patents and is teaching two sessions at this year’s Short Course as well as presenting at the conference during the Society Meeting.

    Dr. Dillingham’s first education course on Friday will examine the basic principles of adhesion and surface chemistry: how they are inextricably codependent and what the nature of their relationship is. The concepts he’ll be discussing is the science at the heart of all the work BTG Labs does. It’s this foundation that has allowed us to build an extensive customer base within a wide range of industries to develop and enhance manufacturing processes.

    The next course Dr. Dillingham will be leading takes the fundamentals of the first course and expands on them by exploring how to analyze and control the chemical makeup of a surface. The understanding that comes from the surface analysis allows for the proper control of the surface chemistry which, in turn, makes it possible to reliably predict adhesion success. This correlation between chemistry and adhesion is the fuel that powers BTG Labs’ technology.

  • Tom McLean’s distinctive voice can often be heard throughout the halls of BTG Labs. I sat down with President and Chief Growth Officer of BTG Labs to learn more about the man behind the voice.

    If you could, please walk me through the steps of your career.

    The career is dominated by software. I started working in the software business in ‘76. At that time, when you told people that you worked at a software company, they didn’t even know what it was. If I was at a cocktail party and said software, people would usually think ‘software’ referred to clothing.

    “Anyway, software from the early days was meant for computers the size of a warehouse. Things that were once done on computers costing millions of dollars are now done on your cell phone for almost nothing.”

    “There are similarities between Ci-Vision [where Mr. McLean was President] and BTG Labs. Ci-Vision is a vision inspection company using cameras, lights, and software, and BTG Labs uses cameras, lights, and software to inspect products, so it is also a vision company in many ways. Software is key in both situations. The more powerful your software, the more value you provide. We have a sophisticated scientific instrument here [the Surface Analyst™], which has important hardware elements, but software is also key.

    “I started my career as a programmer with a goal of going into sales and marketing. I was successful at sales, and over time, moved to product management, which I enjoyed most. To me, it is the most exciting area of any company. At BTG Labs, product management determines what features go into the next release of a product and the overall product direction. We blend what the market needs and wants, and what we can physically develop, not unlike other companies I have managed.” …Read More

  • Challenges often arise when verifying critical surface processes on the factory floor when measuring hard to reach areas and varying angles. The Surface Analyst conquers those challenges with the unique ability to measure on vertical surfaces, which include assembled parts and hard to reach spots. This allows for easier surface analysis on the factory floor.

    This ability is possible because of patented Ballistic Deposition which deposits a pulsed stream of micro droplets with enough kinetic energy to overcome surface roughness and textures.

    A few examples of the Surface Analyst’s ability to measure on vertical surfaces on the factory floor:

    • Airplane wings prior to bonding, painting, and repair
    • Canopy of jet fighters after cleaning
    • Wind turbine blades prior to bonded repair
    • Silkscreen bottles post flame treatment
    • Ship hulls prior to painting and bonding
    • Interior of automobile headlights prior to application of anti-fog coating
    • Windshield bond lines prior to sealing
    • Class A paint surface for decals applications and reapplications
    • Measuring appliances after metal cleaning and prior to power coating

  • 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

  • Thanks to advancements in powertrain manufacturing, sealing processes have improved assembly efficiency. Formed-in-place gaskets (FIPG) are replacing traditional mechanical fasteners as they are more cost effective, stronger, and easier to apply. However, adhesive bonding rather than mechanically fastening presents different challenges and requires new protocols.

    Lead Sales Engineer Lucas Dillingham has presented “Defining Cleanliness in Powertrain Manufacturing for FIPG Applications,” at several events and automotive factories. BTG Labs works with numerous automotive manufacturers on surface chemical cleanliness and what it means for assembly.

    Traditional millipore tests reveal particulate contamination, but on a sealing surface, one must detect chemical contamination. To adhere successfully, surface cleanliness on a chemical level is vital.

    A byproduct of automotive manufacturing processes is contaminants that are detrimental to adhesion. Processes entailing unwanted contaminants include:

    • Die-casting
    • Machining
    • Washing
    • Assembly

  • How Clean, is Clean Enough?

    by Emily Walsh May 2017

    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
