• Cleanliness in product finishing is critical for several reasons. For example, particulates generated in casting and machining processes must be effectively removed to prevent premature wear of sliding and rotating parts. Because of this, one of the final steps in component manufacture is the cleaning process. Washer systems can be quite effective at removal of particulate contaminants. However, performance of bonding, coating, and finishing operations are not dependent on particulate removal efficiency, but rather on the chemical cleanliness of the surface. These processes depend on being able to establish a strong and stable interface with the part surface, which requires establishing and controlling surface cleanliness on a molecular level. This trend toward high-performance adhesive bonding and coating is forcing a reevaluation of the performance of parts washers.

    Primary Topics:
    • The meaning of surface cleanliness which goes beyond particulates.
    • Quantifying parts washers
    • How to measure surface cleanliness
    • Establishing strong interfaces that are ready for successful adhesion

  • This webinar delves into the challenges manufacturers face when establishing a bond. The success of  printing, painting, sealing, or coating relies on the ability to control the bond surface. BTG Labs’ Surface Analyst uses contact angle measurements to provide insight into the cleanliness level of a surface. This shows the manufacturer how prepared a surface is for bonding.

    The Webinar Answers these 4 Questions about Optimizing the Bonding Process:

    1. Why it’s important to know the condition (contact angle) of incoming material, whether it’s from a supplier or out of a parts washer.
    2. Why it’s necessary to know how your material responds to processing, i.e. plasma, etc.? Is the in-place processing treatment actually cleaning your product’s surface like it should?
    3. How long does the processing treatment last until it is no longer effective?
    4. What is the appropriate contact angle to guarantee performance
