• Most polymers contain many non-polymeric components intended to stabilize, toughen, color and lubricate the final product. Certain classes of these additives are capable of migrating to the surface. This additive migration can create a surface that has a composition very different from the bulk of the polymer. If the manufacturing process includes an interface between the polymer and an adhesive or paint, or in the case of a medical device, contact with human tissues, additive migration to the surface (blooming) can have serious consequences. Blooming represents a form of contamination that can result in adhesive or paint failures or worse.

    This webinar discusses:

    • The origins of blooming
    • Common additives that are subject to blooming
    • Strategies for detecting, controlling, and avoiding issues associated with blooming.
  • Primary Topics:
    • The Meaning of Surface Cleanliness–Going Beyond Particulates.
    • Quantifying Parts Washing
    • 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
