  • In the diverse and ever-growing world of medical devices, particularly those involving polymeric tubing, it is always crucial, and not always easy, to test and definitively guarantee the adhesion of your bonds and coatings. In the pursuit of bringing solutions to adhesion issues, BTG Labs is proud to be participating in the third annual AMI Medical Tubing Conference where our Custom Applications Scientist and Research and Development Chemist, Elizabeth Kidd, will be presenting the paper “UTILIZING WATER CONTACT ANGLE MEASUREMENTS TO VALIDATE CHANGES IN POLYMERIC TUBING SURFACE CHEMISTRY” on Tuesday, October 2.

     

    Understanding and measuring the surface energy of your device is crucial to ensuring long lasting adhesion. This presentation will walk attendees through:

  • solving surface adhesion in tight areas

    What do both of these statements about surface adhesion have in common?

    • “We need to measure surface quality of the teeth on a gear to make sure the coating stays on.”

     

    • “We need to make sure the coating on our tubing is uniform, but we can’t measure a curved surface with our current surface testing method.”

    The answer?

  • surface cleanliness measuringPerforming any kind of inspection on small parts can be difficult. When measuring for surface cleanliness, accessing small parts can be even more challenging, especially when measuring on the factory floor.

    With the Surface Analyst, measuring surface cleanliness on small parts has never been easier. This handheld instrument is fast, easy, accurate, and non-subjective allowing for precise measurements, right on the factory floor.

    With specialized measurement heads and a tether to allow access to small parts, manufacturers can verify surface readiness to bond, paint, clean, coat, print, or seal. The Surface Analyst optimizes manufacturing, repairs, and maintenance. …Read More

  • BTG Lab’s recently held another successful webinar. Hosted by Products Finishing and presented by Dr. Giles Dillingham, the webinar emphasized the importance of monitoring cleaning processes and explored different ways to measure surface cleanliness.

    In the webinar, Dr. Dillingham discusses measuring surface cleanliness as a way to quantify cleaning processes. By measuring the success of cleaning processes, manufacturers can determine the ideal solution for their application.

    Precisely evaluating cleaning processes with water contact angle is a fast, easy, accurate, quantitative to way to gain ensure consistency and precision on the factory floor.

  • 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

  • Teflon is a household name that commonly invokes images of eggs sizzling on a skillet, spatulas flipping pancakes, or rice steaming in a pan.

    But, there is much more to this magical non-stick coating.

    Teflon, a brand name for PTFE (polytetrafluoroethylene), prohibits food from sticking to pots and pans because of its hydrophobic properties.

    As a low-energy, fluorocarbon solid neither water nor water containing substances can influence the surface. This means that nothing will stick to the surface or penetrate it.

    Today, Teflon has improved culinary pursuits and made cooking more accessible, but that isn’t the only field PTFE has influenced.

    The medical device industry would not be what it is today without PTFE. As medical devices work intimately with the human body, they must be completely sanitary, inert, and harmless.

    With its lubriciousness and impenetrable properties, PTFE is used to coat a variety of medical devices such as catheters, surgical equipment, balloons, bladders, and implants.

    But, PTFE only works when the coating itself sticks to the surface. This requires proper surface preparation which can be challenging in any manufacturing floor. It’s especially difficult in medical device manufacturing as specifications are so high and there is no room for failure.    …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 year for Memorial Day weekend, my family would pack up the station wagon and head to the lake. The weekend would be filled with red, white and blue, firing grills, festive picnic tables, and bathing suits. My mother would chide me to apply sunscreen before doing anything. And time after time, I would jump in the pool first. The sun screen could wait. I had been pining all winter for the water and some smelly, greasy paste wasn’t going to stop me.

    And then I would fry.

    I’ve since learned to appreciate the importance of sunscreen, but perhaps that is because it is much better than when I was younger. It’s less greasy and smelly, can withstand sweat and water, and better absorbs into the skin—thankfully preventing that touristy semblance.

    Skin care manufacturers work constantly to improve their brand. With a product that works so intimately with the human body and at times for important applications such as UV protection, failures are not acceptable. Yet, developing skin care products comes with challenges. Testing on artificial skin falls short of the real thing as skin types vary greatly. However, in-vivo testing is nearly impossible. …Read More
