• 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.
  • Successful adhesive bonding requires precise control of the physical and chemical properties of a vanishingly small volume of material: the first few molecular layers that surround the interface.

    This requires developing a sensitivity to the factors that affect this region by imposing effective process control protocols.

    This webinar will review the requirements for high-performance surface treatment processes, strategies for developing these processes for new material systems, and protocols for control of these processes after implementation in manufacturing.

    Primary Topics:
    • Basic principles of adhesive bonding for joining composite structures
    • Common composite surface preparation methods, their advantages and disadvantages
    • Development of surface treatment processes: how to evaluate and optimize performance
    • Deployment of adhesive bonding processes in manufacturing: how to ensure control to achieve consistent bond performance

  • 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

  • The success of bonding and printing to thermoplastics depends on effective control of a remarkably thin zone on the surface of a polymer.

    Seemingly subtle changes in processing or composition can result in dramatic changes in the surface properties that control adhesion and product quality. This webinar discusses the fundamentals of adhesion and relates this to surface engineering of thermoplastics via techniques such as flame, corona, and plasma treatment.

    The effects of surface active additives are presented along with techniques for detecting their presence and understanding their effects on adhesion. Practical strategies for process development and process control are presented in a way that provides participants with useful tools for improving product quality and consistency

    Primary Topics:

    • The Nature of Thermoplastics and why Understanding and Controlling the Surface is important for Bonding.
    • The Fundamentals of Adhesion on polymers and how to Optimize flame, corona, and plasma treatments.
    • Detecting Contaminants on the Surface that could be Detrimental to Adhesion.
    • Useful Strategies for Process Development and Process Control to Improve Product Quality and Consistency.
  • 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
