  • 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.

  • The BTG Labs suite of tools, that enable manufacturers and technicians to fully control their adhesion processes, has a new addition. The Surface Analyst 2001 introduces new levels of ease, simplicity and accuracy to manufacturing processes, providing the confidence that the surface will stick.

    This handheld tool is an entry-level surface inspection device that harnesses the power of the BTG Labs’ technology to precisely meet the needs of any manufacturing plant floor, field service troubleshooting, or processes that include heavily repeated surface preparation and inspection steps. The 2001 is built to be used in any environment and is sturdy enough to take accurate measurements under any circumstances.

    There’s a logical fallacy akin to a “what’s good for one is good for all” mindset that is devastating when applied to surface treatment in adhesion processes. Polymers are rapidly being developed and synthesized for niche applications to push the limits of current physical properties of materials. Polymers that are available today did not even exist a few years, or even months, ago. These different materials possess very particular molecular qualities that require distinct treatment approaches in order to compensate for their differences.

     New polymer materials enhance the aesthetics and safety of cars.

    In order to utilize these cutting-edge plastic technologies, manufacturers need to be aware of the effect on the full material system – the baseline material, the adhesion, and outcome of bond performance.

    Diversified polymer use has seen huge advances in consumer goods industries

    The chemical make-up of the baseline material surface is where it all begins and controlling this aspect of the process can stop adhesion failure at the source. This is, however, often the most overlooked and least understood component of successful adhesion.

  • click here to view plasma treatment webinarPlastics are ubiquitous a material as they come, and there is nary an industry that does not utilize them in an adhesion application; medical device, automotive, aerospace, consumer goods, and flexible film and packaging industries all exploit the versatility of polymers in manufacturing. Take a closer look at medical device and automotive industries and you’ll find that the same polypropylene used to make car bumpers in the automotive is also used to make life-saving implantable medical devices.

    Polymers are generally chemically stable materials. While this is a desirable quality for other purposes, it is the industry’s greatest challenge to overcome for adhesion applications (coating, bonding, printing, priming and painting). In order for these materials to adhere successfully they have to undergo some type of surface activation process, like plasma treatment. This process will impart chemically reactive groups on the surface and increase chemical reactivity. This reactivity is a quantifiable material property called surface energy. Plasma treatment is a convenient, cost effective means of achieving surface activation of polymers. Before the plasma treatment can accomplish the proper activation of the surface, the chemistry of the polymer must be considered.

    This week BTG Labs and Plasmatreat got together to co-present a webinar that de-mystifies plasma treatment as it relates to polymer chemistry.

    Understanding surface state at each manufacturing step will allow you to gain complete control over your surface treatment and bonding operation. Here at BTG Labs, we provide a process control check that quantifies that surface state with a simple number.

    Control the process, control the number, control the product.

  • What is a Critical Control Point?

    A Critical Control Point (CCP) is any point in the manufacturing process where the surface condition of a material has the opportunity to change—intentionally or unintentionally—and impact adhesion, in a positive or negative way.

    Why should you care about them?

  • As the wind energy industry grows—by 2020 it is expected to provide 10% of the nation’s electricity— wind turbine manufacturers must strive for the most reliable and efficient product that operates reliably and seamlessly. Adhesion failures in the field, are unacceptable and even dangerous, but still occur.

    Wind turbine manufacturers are making it a priority to overcome adhesion failures in the field and implement ways to ensure repairs only need to be done once. Currently, wind turbine repair is extremely expensive: in most cases, the part must be shipped back to the manufacturing plant for repair. And most importantly, turbine failure could be damaging and dangerous to what could be in the vicinity.

    Adhesion failures most often happen due to improper surface treatment prior to adhesion. Optimizing adhesion processes and gaining control of the bond surface guarantees a reliable bond and prevents failures in the field.

    As a result, wind turbine manufacturers are turning to the best in surface cleanliness gauges: The Surface Analyst.
