  • The competitive nature of the automotive industry requires manufacturers to engineer the ideal product; failures, no matter how small, are unacceptable and can bring heavy consequences.

    A particular problem that plagues automobiles is condensation collecting on the inside of headlights. High performance automotives must not only perform well mechanically but must also maintain an exceptional aesthetic. Water droplets condensing on the insides of headlights are unappealing and unacceptable to consumers.

    In order to prevent that condensation, manufacturers use an invisible coating on the inside of polycarbonate headlight lenses called anti-fog.

    This coating is applied via spray application which can be difficult and inconsistent due to several variables: low energy mold releases left on the surface; environmental contaminants; contaminants from handling; uneven spray application; and incorrect coating solutions.

  • 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

  • Home exhibiting Tesla solar roof. Image by Tesla.

    Last month, Elon Musk announced the availability of Tesla’s new solar roof. These solar roofs are made to masquerade as tasteful, modern shingles; their attractive panels offer roofs from sleek modern to French slate. The solar panels are hidden in a pane of glass which contains a hydrographic coloring–a process that uses water to apply printed designs– to provide texture.

    But, these shingles must not only look good, like all solar panels, they must be tough enough to withstand elemental threats.

    Wind, rain, snow, sun, extreme temperatures–these are all stresses to any structure, especially solar panels. Because solar panels serve as an energy source, there is no room for failure in the field. The bonds that keep them together such as bonds between dissimilar materials, bonds on low energy polymers, coatings, laminates, and seals, must withstand the stresses as well. That’s why solar panel manufacturers turn to the Surface Analyst.

  • 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

  • There’s nothing like arriving at the course on a fresh spring morning. The sun is low, casting long shadows across the green mounds, foggy rays bring hints of warmth, a fresh, dewy smell fills the air, and everything is the most vivid green of the year.

    It’s time to get out the bag, polish the clubs, and maybe replace the grips. The courses are meticulously manicured. The weather is warming. It’s spring and we’re in the midst of golf season.

    Whether it’s a tournament or a casual round with a buddy, relying on your equipment is reflexive. Although, mishaps do occur—grips slip, shafts bend, and balls lose their print—top  golf manufacturers use the Surface Analyst to produce a reliable product that will hold up all season long. …Read More

  • Roosevelt University, Image by Chicago Tribune

    Roosevelt University, a liberal arts college in the Loop of downtown Chicago perfectly contrasts antiquated and contemporary architecture. Roosevelt’s first venue, constructed in 1889 just in time for the World Fair, is 17 floors of beautiful Art Nouveau structure. The Auditorium Building encompasses ornate railings and scaffolding, topping off with a regal library and a lofty tower overlooking Grant Park. However, because of its age, the Auditorium Building demands constant attention and is inefficient in the frigid Chicago winters and hazy summers.

    Their new building, the Wabash Building, erected in 2012 is just the opposite. Its 32 towering floors of curved glass superintends the Auditorium Building, arriving amongst the structural giants of Chicago. Illustrating the epitome of modern design, this highly efficient, state of the art structure is LEED certified.

    When looking up at the two buildings, old charm vs new-age sleek, the phrase comes to mind: they just don’t make things like they used to. But, there’s necessity behind this. As the global population rises, infrastructure becomes denser, and resources become scarce, engineers concentrate on building smarter. Designing a building that spares no expense—in terms of efficiency in operation and manufacturing of these smarter materials—is pivotal. This all begins in the research and development lab and extends to the manufacturing floor. Materials and processes are developed to allow for more efficiency in both the production of materials and the final construction. Guaranteeing bonds will hold; paint, print, and coatings will stick; seals will persevere; and cleaning processes will clean effectively is crucial to manufacturing a product that will withstand stresses of any structure.

    That is why more and more manufacturers are turning to the Surface Analyst™. This hand-held instrument ensures any surface is ready for effective bonding, coating, cleaning, sealing, printing, or painting. The ability to verify and quantify critical surface processes on the manufacturing floor is the keystone to efficient manufacturing and smarter structures.

    A high-grade window manufacturer, for example, uses the Surface Analyst to verify plasma treatment on vinyl window frames prior to sealing. This guarantees the windows will efficiently heat or cool a structure while also withstanding the elements of rain, wind, and snow. …Read More

  • Surface Analyst Inspection on Engine Casing

    Manufacturers working with metal are all too familiar with the obstacles that come along with coating, painting, bonding, printing, or sealing it. While the uses of metal in manufacturing are countless and exist in numerous industries, the common denominator is ensuring the appropriate surface cleanliness prior to surface critical processes to guarantee successful adhesion. Common surface cleanliness gauges—dyne inks and water break—are subjective and do not offer quantitative results. Water break can be messy and time consuming and dyne is destructive to the part and dangerous to the user. While these methods can offer some insight into surface cleanliness, they are less than ideal.

    BTG Labs Surface Analyst is a fast, easy, accurate, and non-destructive surface cleanliness gauge that tells the user right on the manufacturing floor how prepared the surface is to bond. This hand-held instrument improves surface processes and guarantees a bond will stick. Numerous manufacturers in industries such as consumer goods, automotive, and aerospace, have implemented the Surface Analyst in their specifications to improve their critical metal surface processes. …Read More
