    A Meeting of the Adhesion Society

    Annually, scientists, engineers, manufacturers, and students professionally concerned with the science and technology of adhesion, gather for a meeting of the Adhesion Society. Since 1978, this gathering has brought together these great minds to discuss, present, and learn the results of research and the newest findings in the science of adhesion.

    BTG Labs’ Chief Scientist Dr. Giles Dillingham has been presenting regularly since the late 1980s. In 2006, he was elected Fellow of the Adhesion Society in recognition of his contributions.

    This year he will be presenting at the 40th Annual Meeting happening February 26 – March 1 in St. Petersburg, Florida. Dr. Dillingham will present on a paper entitled, “Control of Cleaning Processes to Maximize Sealant Performance.”

    Controlling the cleaning processes of sealing surfaces in power train components is the key to long life and low warranty percentages in automotive manufacture. One of the final steps in the die-cast and machining process is cleaning. Current commercial washer systems can be quite effective at removal of particulate contaminates. The efficiency of washer systems has traditionally been evaluated using the Millipore Test. This method measures the mass of particulates post washing.

  • 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

    Controlling Surface Condition in FIPG Application

     

    Increasingly, FIPG processes are replacing traditional gaskets for a variety of automotive applications such as air filters, oil filters, door panels, and external engine parts. The advantages include cheaper material cost, higher throughput capability, ability for assembly at the supplier, and greater control over sealing processes. These advantages, however, come with processing challenges that the manufacturer must take into account; namely the surface of the part they are sealing.

    Within the automotive industry, a common FIPG application is RTV (room-temperature-vulcanization). Defining and controlling surface condition prior to applying an RTV silicone sealant is critical for a successful seal. Variables such as inadequate cleaning, over-used washing fluid, excess oil contamination, and poor handling can wreak havoc on an RTV application process. This can lead to rework, customer complaints, and warranty claims after the customer purchases the product. So how does an OEM or supplier design and control an appropriate FIPG process that will be successful?
