    Preparing a Ship Hull for Coating and Painting

    Manufacturing a product to withstand the environmental stresses of wind, rain, and sediment is challenging enough. But, when you add saltwater and wave action to the mix, the detrimental threat of corrosion increases significantly. A coating adhesion test is important for quickly testing a surface before spending hours of work, coating and painting the hull just to find out that the surface lacks the adhesive quality enough to withstand the elements.

    Anti-corrosive or anti-fouling coatings and protective paints serve to protect ships against those environmental threats.

    But, the coating or paint is only as strong as its adhesive quality. If the adhesion fails, the coating or paint chips and the ship becomes vulnerable to corrosion. Failures in the field can be both costly and dangerous.

    Ensuring quality adhesion is the key to guaranteeing successful protection. But, how can quality adhesion be achieved? A proper coating adhesion test should be done beforehand to gauge the surface preparedness before painting or coating occurs.

    It all starts at the surface. …Read More

  • Of all the challenges manufacturers face, creating and optimizing critical surface processes for various materials can be very difficult. Traits such as location, size, shape, and texture can add to the challenge. The success of any critical surface process requires an in-line, fast, easy, and accurate verification method.

    That’s why more and more manufacturers are turning to the Surface Analyst. Whether it’s bonding, painting, printing, cleaning, coating, or sealing, BTG Labs’ Surface Analyst optimizes critical surface processes and monitors surface treatment on virtually any surface so the product is guaranteed to deliver.

    BTG Labs engineered the Surface Analyst to adapt to any application directly on the factory floor. Patented Ballistic Deposition deposits a stream of micro-droplets on the surface; these micro-droplets contain kinetic energy which allows the drops to overcome various textures and different angles without interfering with measurement accuracy. The drop size can also be adjusted so that measurements can be taken on any sized surface from a giant wind turbine to a minuscule medical catheter.

  • converting quarterlyCheck out BTG Labs’ recent article published in Converting Quarterly’s Q3 issue. The official publication and technical journal of International Metallizers, Coaters, and Laminators, Converting Quarterly is the go-to publication for web processing, converting, and finishing industries.

    Industry professionals and researchers contribute to the magazine and offer the latest in research and development and industry trends.

    Dr. Giles Dillingham, Chief Scientist of BTG Labs, contributed to the most recent issue with an article entitled, “Film surface properties: Techniques for measurements and control of treatment level.”

    The success of print quality and adhesion quality of films relies on precise control of the surface. Manipulating surface composition with methods such as flame, corona, and plasma treatment can increase surface energy and thus improve the integrity of print and adhesion on film. …Read More

  • BTG Labs Takes on Vegas

    by Emily Walsh October 2017

    Last week, BTG Labs traveled to Las Vegas for the largest and most comprehensive packaging event in North America: PACK EXPO 2017. BTG Labs Sales Engineers met with leaders of the packaging industry to exchange the latest trends and advances.

  • 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

  • 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.

  • BTG Labs Presenting at AA&S 2017

    by Emily Walsh May 2017

    Top aerospace manufactures recruit state-of-the-art equipment to ensure precision and perfection. One thing the best of the best have in common: the Surface Analyst. BTG Labs first engineered the Surface Analyst through an SBIR (Small Business Innovation Research) grant to collaborate with the USAF (United States Air Force). Born out of necessity, the instrument was engineered to verify a surface’s readiness to adhesively bond fasteners.

    Today, the Surface Analyst is written into Lockheed Martin specifications for fighter jet manufacturing; it played a major role in the development of the F-35; and its expertise is trusted on all factory floors of top aerospace manufacturers.

    While the Surface Analyst use has spilled outside of the aerospace box, BTG Labs remains closely tied in the aerospace industry and that is why you will find us at AA&S 2017. Taking place May 22-25 in Phoenix, Arizona, The Aircraft Airworthiness and Sustainment Conference attracts leaders of the aerospace industry from around the world.
