  • Connect with BTG Labs at CAMX 2017

    by Christian Meininger December 2017

    BTG Labs will exhibit at CAMX 2017, The Composites and Advanced Materials Expo, which will run December 11-14 in Orlando, FL. BTG Labs will host booth N17. Visit our booth for live demonstrations of the Surface Analyst.

    BTG Labs’ CEO and Chief Scientist Dr. Giles Dillingham will give a presentation entitled “Rapid Development of Surface Treatment Processes” on Wednesday, December 13 at 2:00 pm, Room W209A.

    Giles will discuss the use of rapid water contact angle measurements to screen surface preparation methods for adhesive bonding processes, and the transition of these measurements into the manufacturing environment to ensure long-term control. The course will review successful application of water contact angle measurements in laser surface preparation, peel ply and plasma treatment and secondary bonding of dissimilar materials in aircraft repair. Add this course to your MyCAMX schedule here.

    Giles will also be teaching a short course along side BTG Labs’ partner Lou Dorworth of Abaris Training Resources. This short course titled, “Surface Preparation & Adhesion Principles: Successful Bonding of Composites” will examine methods for achieving long-lasting bonds to laminated RFP composite structures by focusing on techniques to ensure proper surface preparation and surface treatment.

    This course will take place Monday, December 11 from 2:00 pm – 5:00 pm in room W207C. Add it to your MyCAMX schedule here.

    If you bond, coat, clean, seal, print, or paint, be sure to add the BTG Labs booth to your schedule here.

  • Parts washers play an integral role in manufacturing, especially on machined parts and bonding surfaces. Prior to coating, sealing, painting, and welding, parts washers help remove contaminants generated from fabrication to facilitate stronger bonds.

    But, for a reliable bond to form, the surface must not only be free of particles, it must also be chemically clean. Thus, quantifying and analyzing parts washer effectiveness in removing chemicals is the key to ensuring the desired surface is achieved.

    The importance of monitoring cleaning processes in preparation for bonding is becoming increasingly necessary as sealing processes are rapidly replacing traditional mechanical fasteners and gaskets.

    However, when sealing, the surface must be clean and clear of contaminants to guarantee the bond. The Surface Analyst monitors and optimizes washer systems to ensure the part comes out chemically clean and ready to hold a reliable bond. …Read More

  • Medical Device Applications

    by Emily Walsh February 2017

    BTG Labs’ origins are in the research and development of adhesives and coatings, including the development of a corrosion resistant antimicrobial coating–often used in the medical device industry. The Surface Analyst is the ideal surface cleanliness gauge for the medical device industry in that it is completely non-destructive, precise, quantitative, and able to measure on various substrates including rough, convex, and concave surfaces. BTG Labs’ twenty plus years of expertise can assist in the optimization of medical device manufacturing processes to meet the highly-tailored specs of this industry to manufacture more reliable, fail resistant products.
