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.
Last week, BTG Labs exhibited and presented at ANTEC 2017. We were pleased to connect and exchange intelligence with leaders in the plastics industry.
Our booth featured the Surface Analyst, which uses contact angle to measure surface cleanliness of a material. This monitors the surface preparation process and ensures readiness to bond, print, paint, coat, or seal which can be challenging on plastics. More and more, plastics manufacturers are turning to the Surface Analyst for guaranteeing their surface treatment and final product.
Along with exhibiting, BTG Labs’ Chief Scientist Dr. Giles Dillingham presented the paper, “Rapid Evaluation of Surface Properties of Medical Tubing for Process Development and Quality Assurance.” The paper explains that the key to manufacturing high performance medical devices is understanding and controlling surface properties. Crucial characteristics of medical tubing such as wettability, adhesion, antithrombogenicity, and biocompatibility depend on only the top few molecular layers of a surface. Dr. Dillingham discusses research done with the Surface Analyst for highly sensitive surface measurements on medical tubing to control coating application. …Read More
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
