    Watch the latest BTG Labs’ video showing the Surface Analyst’s revolutionary method for optimizing critical surface processes in manufacturing.

    This video demonstrates how the Surface Analyst provides total surface quality control for manufacturers who previously had ineffective methods, or no method at all. The instrument’s portability, ease-of-use, intuitive GUI, and rechargeable battery provides a surface cleanliness gauge that verifies surface treatment directly on the factory floor.

    Maintaining control of a surface allows the manufacturer to guarantee bonds, paint, and adhesives. The Surface Analyst provides instant quantitative surface cleanliness measurements to verify these bonds will hold reliably.

  • conPolymers are some of the most common base materials used in automotive parts. Polypropelenes, Polyolefins, and ABS plastics are used in dashboards, door panels, bumper fascias, liftgates, sensors, and increasingly exterior doors and fenders. A polymer is a low surface energy material that typically needs some form of surface processing prior to bonding an assembly, encapsulating a sensor, painting an interior control knob or an exterior bumper fascia. These materials also tend to show high contamination with mold releases that can be tough to remove and will essentially guarantee unsuccessful adhesion or coating.

    There are a variety of surface processing methods used in the industry to help remove contamination and increase the surface energy of these polymer materials. These processes include flame treatment, plasma treatment, corona treatment, and solvent wiping. Another option is to utilize specialty paints and adhesives that tolerate lower energy substrates. There are pitfalls, however, to implementing any of these methods that manufacturers need to be aware of. Understanding the nature of these surface-critical systems is the only way to guarantee success in the final result. Control of the inputs means predictability and control of the output.
