    Automotive Applications

    BTG Labs boasts relationships with some of the world’s top automotive manufacturers and tier 1 suppliers. The Surface Analyst™, a fast, easy, accurate, and non-destructive surface cleanliness gauge, quantifies how prepared a surface is for bonding, coating, sealing, painting, printing, or cleaning from the lab to the manufacturing floor. Therefore, it can be implemented in a variety of applications. This non-subjective, user-friendly system allows users of all training levels to measure surface cleanliness levels in either a pass/fail mode or exact contact angle degree in under 2 seconds. …Read More

  • Surface Requirements of Aluminum Castings

     

    Automotive manufacturers widely utilize aluminum castings as the most successful way to create aluminum parts. However, this process can involve inorganic contaminants on the surface which interfere with potential bonding, sealing, or coating. BTG Labs conducted a surface analysis test for an automotive company by measuring contact angle with the Surface Analyst™ to determine the condition and cleanliness level of their aluminum castings.

    Aluminum Casting

    Aluminum castings can sometimes entail silicone mold release or conversion coating which spells disaster for bonding, sealing, or coating. So the surface preparation processes of these castings plays a pivotal role in the success of any adhesion. For this analysis, BTG took surface measurements of the company’s machined engine front engine cover sealing surfaces in 10 different locations approximately 1.5″ apart. BTG measured in three different states: as received; after multiple isopropanol wipes; and after multiple hexane wipes. They also measured after treatment with 220-grit aluminum abrasive paper.
