  • 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.

    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?

    It all starts at the surface. …Read More

  • In some industries–including film and flexible packaging–dyne is the primary language. BTG Labs’ Surface Analyst uses water contact angle measurements as a fast easy, objective, and non-destructive alternative to dyne inks.

    The main concern we hear from manufacturers is that both the suppliers and the customers speak dyne as their standard.

    The answer is the Surface Analyst’s Dyne Mode. This unique feature takes the Surface Analyst’s default contact angle measurement and automatically converts the measurement into a dyne/cm readout, directly on the instrument. This mode allows manufacturers to maintain their investment in the dyne measurement language.

    BTG Labs believes in dyne measurements, but not dyne inks. Manufacturers using dyne inks struggle with inaccuracy and subjectivity, leaving much room for error. Furthermore, because of dyne inks’ destructive nature, users can’t measure on the actual part. This leaves dyne inks virtually impossible for testing the part on the factory floor. …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.

    In 2014, a large manufacturer of automotive exteriors and interiors encountered a problem consistently adhering paint to their dashboards due to an inappropriate use of their flame treatment.

    Flame treatment is a popular and notable procedure that can successfully modify the surface chemistry of a polymer, readying it for adhesion. Although flame treatment is an effective solution, determining the amount of treatment can be a delicate procedure. The over-flaming of these highly sensitive polymers can lead to polymer reorientation due to localized melting and ultimately, destruction of the surface.

    In this case, however, the manufacturer was not utilizing flame treatment to monitor their surface cleanliness. Instead, they used it to deflash excess material on the edges of their dash boards. The edges of the dashboard were being over-flamed, hindering the polymer’s surface adhesion ability. This, in turn restricted paint from correctly adhering to the edges of the dashboard. The company needed a way to determine the appropriate amount of flame treatment.

  • 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.

  • 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.
