  • How Clean is Clean Enough?

    by Emily Walsh May 2017

    Manufacturers often encounter a similar puzzle, when cleaning invisible contaminants from a surface, how do you know when the surface is clean; how clean is clean enough? This is a common question that manufacturers ask when preparing their surfaces for bonding, coating, sealing, printing or painting. Until now, there hasn’t been an objective and reliable way to answer this question. Successfully cleaning a surface directly correlates to the adhesive ability of the surface. In order to get something to stick reliably the surface must be clean. How we define that parameter is different for a variety of materials.

    For example, you clean your car differently than you clean your dishes. Why? Because a car rides on the road through rain, smog, dirt, maybe mud, and the other is a vehicle for your food.

    At BTG Labs, our answer to the “clean enough” question is, “Depends on what you’re doing.” There are dozens of critical surface preparation processes that exist for a number of different applications. A handful include:

    • Flame treatment on polypropylene bumpers prior to painting
    • Plasma treatment on PET catheters prior to coating
    • Hand sanding and solvent wiping on aircraft nut plates before adhesively bonding to composite
    • Grit-blasting titanium golf clubs in preparation of bonding to composite
    • Corona treatment on film for packaging prior to metallization, lamination, or coating

  • Surface Analyst Inspection on Engine Casing

    Manufacturers working with metal are all too familiar with the obstacles that come along with coating, painting, bonding, printing, or sealing it. While the uses of metal in manufacturing are countless and exist in numerous industries, the common denominator is ensuring the appropriate surface cleanliness prior to surface critical processes to guarantee successful adhesion. Common surface cleanliness gauges—dyne inks and water break—are subjective and do not offer quantitative results. Water break can be messy and time consuming and dyne is destructive to the part and dangerous to the user. While these methods can offer some insight into surface cleanliness, they are less than ideal.

    BTG Labs Surface Analyst is a fast, easy, accurate, and non-destructive surface cleanliness gauge that tells the user right on the manufacturing floor how prepared the surface is to bond. This hand-held instrument improves surface processes and guarantees a bond will stick. Numerous manufacturers in industries such as consumer goods, automotive, and aerospace, have implemented the Surface Analyst in their specifications to improve their critical metal surface processes. …Read More

  • Consumer Goods

    Golf BallThe world of consumer goods is highly diverse so consequently, manufacturing processes are even more varied. From golf clubs to paints to windows to solar panels, consumer goods products face a variety of stresses in the field that can include moisture, impact, contaminants, and environmental stresses. Manufacturers must produce a product to withstand those stresses. BTG Labs’ Surface Analyst™ can do just that. It is a versatile, handheld, accurate, easy to use instrument that can cut down on failure and waste and ensure surfaces are properly prepared to create the strongest bonds whether its coating, printing, painting, sealing, or cleaning. The Surface Analyst measures, monitors, and guarantees from the lab to the factory floor.

    Unraveling Grit-Blasting Effects

     

    This paper is part of an ongoing collaboration between Dr. Giles Dillingham, BTG Lab’s chief scientist, and other members of the University of Cincinnati’s Department of Chemical and Material Engineering, Boeing, and the Materials Directorate of the Wright Patterson Air Force Base to study the effects of grit-blasting on graphite/epoxy composites.

    Grit-blasting, a commonly used surface preparation process  frequently applies to polymer composites. However, very little experiments and observations exist concerning the effects of grit-blasting on the surface properties of composites. …Read More
