  • 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.

  • 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

  • Manufacturers are all too familiar with the challenges of getting a bond to stick and hold. The success of a bond relies on the surface created prior to that bond, so, monitoring and measuring surface processes is the only way to know that the surface is ready to bond reliably.

    BTG Labs’ President Tom McLean and Sales Engineer Lucas Dillingham presented during Plasmatreat’s Open House on the 4 Surface Fundamentals for Successful Bonding in Manufacturing. They presented to industry leaders who can easily relate to bonding and cleaning issues. The presentation was such a success that BTG Labs decided to turn it into a webinar.

    Challenges with establishing a strong, reliable bond, when painting, coating, sealing, or printing are tied into the surface preparation process and the ability to monitor that process. This presentation focuses on the bond surface and what it takes to bond properly to that surface. There is also a comparison of various cleaning methods using contact angles taken with the Surface Analyst.

    While other monitoring processes such as dyne and water break fail to provide quantitative insight, monitoring cleaning processes with the precise and quantitative Surface Analyst tells the user, objectively, whether the surface is properly prepared to hold a reliable bond. …Read More

  • Smarter Surface Processes

    For over a decade, manufacturers and suppliers have spoken the language of dyne when dealing with surface preparation and treatment verification. Because the process of dyne analysis requires users to interpret the way the ink spreads on a surface, it is highly subjective, making the language of dyne precarious. Even so, what could read as a 42 to one user, could mean a 45 or even a 39 to another user. The varying measurement from one user to another is problematic for data collection and analysis. And, training a user is often very time consuming. Another threat to dyne’s accuracy is the fact that when a dyne pen is applied to a surface, the pen tip itself absorbs any contaminants on the test surface and spreads it to other surfaces, thus rendering the ink even more inaccurate over time.

    The Language of the Surface Analyst

    Conversely, the Surface Analyst is non-subjective and produces a quantifiable measurement in the form of a water contact angle. Unlike dyne, the Surface Analyst is fast, easy, accurate, and non-destructive using only highly purified water to take measurements. Therefore, the Surface Analyst can take measurements on almost any surface.

  • Common Surface Energy Tests: Dyne Inks

    by Emily Walsh September 2016

    For years, manufactures have implemented a conventional method of testing surface energy using a polyethylene solution called dyne inks. Dyne ink, when applied to a surface, can reveal the surface’s adhesion potential. But, there’s an inherent problem with the inks themselves…

  • A reliable way to verify surface cleanliness for automotive manufacturers

    Automotive manufacturers who bond, seal, coat, paint, or print now have a reliable way to verify the cleanliness of their surface.

    Higher Performance Materials Call for Higher Demand of Quality

     

    In the automotive industry, there is a constant focus on higher performance materials that provide more with less — better strength, better fuel economy, and better durability at the expense of weight and cost.

    What manufacturers once produced in steel and iron they now make in aluminum. Furthermore, manufacturers are increasingly replacing aluminum with composite. Whether it is a car roof, hood, trunk lid, intake manifold, or dashboard, automotive manufacturers are pushing the boundaries of what they thought was possible for material performance.

    New materials require new coatings, new adhesives, and new paints. And all of these require new process solutions to guarantee an ever-increasing demand of quality.

    A major challenge has been the need to shift to a higher performance material that requires bonding, coating, sealing, painting, or printing. These materials often have more stringent processing specifications to get similar adhesive performance. …Read More
