  • BTG Labs Presenting at AA&S 2017

    by Emily Walsh May 2017

    Top aerospace manufactures recruit state-of-the-art equipment to ensure precision and perfection. One thing the best of the best have in common: the Surface Analyst. BTG Labs first engineered the Surface Analyst through an SBIR (Small Business Innovation Research) grant to collaborate with the USAF (United States Air Force). Born out of necessity, the instrument was engineered to verify a surface’s readiness to adhesively bond fasteners.

    Today, the Surface Analyst is written into Lockheed Martin specifications for fighter jet manufacturing; it played a major role in the development of the F-35; and its expertise is trusted on all factory floors of top aerospace manufacturers.

    While the Surface Analyst use has spilled outside of the aerospace box, BTG Labs remains closely tied in the aerospace industry and that is why you will find us at AA&S 2017. Taking place May 22-25 in Phoenix, Arizona, The Aircraft Airworthiness and Sustainment Conference attracts leaders of the aerospace industry from around the world.

  • There’s nothing like arriving at the course on a fresh spring morning. The sun is low, casting long shadows across the green mounds, foggy rays bring hints of warmth, a fresh, dewy smell fills the air, and everything is the most vivid green of the year.

    It’s time to get out the bag, polish the clubs, and maybe replace the grips. The courses are meticulously manicured. The weather is warming. It’s spring and we’re in the midst of golf season.

    Whether it’s a tournament or a casual round with a buddy, relying on your equipment is reflexive. Although, mishaps do occur—grips slip, shafts bend, and balls lose their print—top  golf manufacturers use the Surface Analyst to produce a reliable product that will hold up all season long. …Read More

  • Visit booth 220 or attend the presentation of Chief Scientist, Dr. Giles Dillingham.

    What is known as The Plastics Technology Conference, ANTEC (Annual Technical Conference) 2017 brings together diverse members of the plastics industry from around the world. Taking place in Anaheim, California May 8-10, ANTEC 2017 showcases the latest technologies and advancements in the plastics industry.

    Dr. Dillingham’s presentation, “Rapid Evaluation of Surface Properties of Medical Tubing for Process Development and Quality Assurance” explores methods of quality assurance testing on sensitive medical tubing. Significant properties of medical tubing–adhesion, wettability, antithrombogenicity, biocompatibility—allow for the ability to deliver fluids, gases, drain, and enter the body effectively. Yet, these properties depend on the top 2-3 molecular layers of the tube’s surface. This is why precise control of the surface is crucial for the success of medical tubing. But, this can be challenging. Laboratory techniques such a FTIR and XPS can reveal surface composition, however, these methods are not practical on the manufacturing floor.

  • 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

  • BTG Labs’ to Present at CMH-17

    by Emily Walsh March 2017

    This week, BTG Labs will attend the CMH-17 PMC Coordination Meeting in conjunction with ASTM D-30 in Salt Lake City, Utah. The purpose of this gathering is to present and collaborate on the latest in composite advances and standards and contribute to document updates.

    CMH-17, the Composite Materials Handbook, is the go to reference and guide for aerospace manufacturers who adhesively bond composite parts. It features standard, vetted composite technologies as well as standardization for data collection and analysis of composite processes. BTG Labs maintains a strong connection with CMH-17 by presenting at working group meetings and contributing to content.

    This year, BTG Labs’ Chief Scientist Dr. Giles Dillingham and Research and Development Engineer Tim Barry will attend the March meeting to collaborate and present.

    Dr. Dillingham and Barry will present BTG Labs’ work to a joint meeting of ASTM committees D30 and D14.80.01 on adhesives and composites. This presentation intends to create a new standard based on BTG Labs’ Surface Analyst™, a handheld instrument which measures water contact angle in 2 seconds to ensure bonding. The proposed standard especially focuses on the instrument’s unique abilities to deposit water drops via patented Ballistic Deposition technology and image drops from above to determine the contact angle.

  • Food packaging and print industries often face the obstacle of adhering to low energy substrates such as polypropylene. Measuring the surface’s cleanliness prior to bonding or printing is the key to successful adhesion. The common method for measuring surface cleanliness, or surface energy on these materials is dyne inks. However, dyne is highly subjective and requires a skilled technician, and because of its destructive nature, dyne can only be used on a sample rather than an actual material on the assembly line. These downfalls often restrict the use of dyne inks.

    This paper examines the relationship between surface energy and adhesion and how water contact angle provides an accurate and quantitative method for predicting adhesion.  The results of this paper reveal that the Surface Analyst, a handheld water contact angle measurement instrument is an accurate and effective indicator of surface energy. …Read More

  • The utilization of composites increases daily in manufacturing as more ways in which to use this advanced material are discovered. Composite is a smart material that provides a lighter weight and stronger product. This advanced material is being used in many different industries, from consumer products like bicycle frames to airplanes. Yet, because the strength is held in the fibrous matrix of the material, composites must be adhesively bonded together as traditional mechanical fasteners can break the fibers and compromise the material’s integrity.

    To guarantee these bonds, BTG Labs’ Surface Analyst™ precisely, accurately, and quantifiably measures the surface’s readiness to bond. BTG Labs’ experience in the field of composites reaches back to the genesis of the Surface Analyst when the USAF turned to the company to engineer a hand-held surface energy measurement device for composite bonding of aircraft. Since then, the Surface Analyst’s composite applications continue to increase and span into many more industries.
