Partnering with Plastics Technology, BTG Labs held a webinar about a topic that’s attracting a lot of attention.
In the webinar you’ll learn about how blooming can be detrimental to adhesion when bonding, coating, painting and sealing and, in the cases of medical equipment failures, can be a tremendous risk. Dr. Giles Dillingham walks through strategies for detecting, controlling, and avoiding issues associated with blooming using methods like contact angle measurement.

Think about your company’s manufacturing operation.
Now, think about fixing your adhesion problems simply by knowing a single number…
What do both of these statements about surface adhesion have in common?[spacer height=”15px”]
- “We need to measure surface quality of the teeth on a gear to make sure the coating stays on.”
- “We need to make sure the coating on our tubing is uniform, but we can’t measure a curved surface with our current surface testing method.”
“We need to be solvent wiping our aluminum before it’s coated/painted/sealed/insert adhesion-intensive process here.”
Technically, that’s correct…you should be.
But is that understanding enough?
Water break testing. Dyne pens. Goniometer. No method at all.
The search for a reliable, repeatable, objective method (i.e. not based on opinion) for measuring surface readiness in manufacturing was a search all too common among our current customers, and these methods are the most commonly tried and (formerly) used among them.
Achieving great adhesion in manufacturing comes down to surface preparation (we call it “Clean to a Number”) and optimal surface prep is the difference between an average product…and an industry-leading one.
But getting there means having an objectively quantified understanding of the top 3 molecular layers of your material surface.
Did we just say “top 3 molecular layers?”
On May 21-24, BTG Labs heads back to Long Beach, CA but this time for the SAMPE 2018 Conference & Exhibition.
Recently in Long Beach for AeroDef, one of the aerospace and defense industries’ most widely recognized conferences, BTG Labs now contributes to this tradeshow that features “the latest technologies and research advancements in the industry.” Maybe you’ve heard of a little instrument called The Surface Analyst?
New industry buzzword?
Or a new generation of process and quality control?
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
BTG Lab’s recently held another successful webinar. Hosted by Products Finishing and presented by Dr. Giles Dillingham, the webinar emphasized the importance of monitoring cleaning processes and explored different ways to measure surface cleanliness.
In the webinar, Dr. Dillingham discusses measuring surface cleanliness as a way to quantify cleaning processes. By measuring the success of cleaning processes, manufacturers can determine the ideal solution for their application.
Precisely evaluating cleaning processes with water contact angle is a fast, easy, accurate, quantitative to way to gain ensure consistency and precision on the factory floor.
Challenges often arise when verifying critical surface processes on the factory floor when measuring hard to reach areas and varying angles. The Surface Analyst conquers those challenges with the unique ability to measure on vertical surfaces, which include assembled parts and hard to reach spots. This allows for easier surface analysis on the factory floor.
A few examples of the Surface Analyst’s ability to measure on vertical surfaces on the factory floor:
- Airplane wings prior to bonding, painting, and repair
- Canopy of jet fighters after cleaning
- Wind turbine blades prior to bonded repair
- Silkscreen bottles post flame treatment
- Ship hulls prior to painting and bonding
- Interior of automobile headlights prior to application of anti-fog coating
- Windshield bond lines prior to sealing
- Class A paint surface for decals applications and reapplications
- Measuring appliances after metal cleaning and prior to power coating
