Plastics manufacturers are all too familiar with the challenges of bonding thermoplastics. Last week, BTG Labs successfully hosted a webinar with Plastics Technology to discuss improving bonding of thermoplastics. The webinar, entitled “Understanding Surface Energy: How to Measure and Control the Surface Properties of Thermoplastics to Maximize Adhesion,” brought in almost 400 registrants.
Presented by BTG Labs’ Chief Scientist Dr. Giles Dillingham who discussed the surface characteristics of thermoplastics. Dr. Dillingham also explored surface treatment processes such as flame, corona, and plasma, and ways to monitor and verify those processes. The ability to understand and measure the surface precisely is the key to successfully bonding thermoplastics.

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.
