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?
Manufacturing a product to withstand the environmental stresses of wind, rain, and sediment is challenging enough. But, when you add saltwater and wave action to the mix, the detrimental threat of corrosion increases significantly.
Anti-corrosive or anti-fouling coatings and protective paints serve to protect ships against those environmental threats.
But, the coating or paint is only as strong as its adhesive quality. If the adhesion fails, the coating or paint chips and the ship becomes vulnerable to corrosion. Failures in the field can be both costly and dangerous.
Ensuring quality adhesion is the key to guaranteeing successful protection. But, how can quality adhesion be achieved?
In 2014, a large manufacturer of automotive exteriors and interiors encountered a problem consistently adhering paint to their dashboards due to an inappropriate use of their flame treatment.
Flame treatment is a popular and notable procedure that can successfully modify the surface chemistry of a polymer, readying it for adhesion. Although flame treatment is an effective solution, determining the amount of treatment can be a delicate procedure. The over-flaming of these highly sensitive polymers can lead to polymer reorientation due to localized melting and ultimately, destruction of the surface.
In this case, however, the manufacturer was not utilizing flame treatment to monitor their surface cleanliness. Instead, they used it to deflash excess material on the edges of their dash boards. The edges of the dashboard were being over-flamed, hindering the polymer’s surface adhesion ability. This, in turn restricted paint from correctly adhering to the edges of the dashboard. The company needed a way to determine the appropriate amount of flame treatment.
Last week, SAMPE hosted a one-day technical conference, the High Desert Chapter, to provide an opportunity for composites manufacturers to touch base before the next full length SAMPE show in 2018.
BTG Labs’ West Coast Sales Engineer Aaron Berding, hosted a booth for the event.
Was this your first time at the show? What were some advantages to a smaller show? What was different about this one?
This was BTG’s first time at the show. The advantage of the small show was that attendees had more time to stop and chat without the overwhelming crowds and busy schedule. They are more willing to stop and chat with your because there were only 75 booths, instead of 300, 500, etc. …Read More
Check out BTG Labs’ recent article published in Converting Quarterly’s Q3 issue. The official publication and technical journal of International Metallizers, Coaters, and Laminators, Converting Quarterly is the go-to publication for web processing, converting, and finishing industries.
Industry professionals and researchers contribute to the magazine and offer the latest in research and development and industry trends.
Dr. Giles Dillingham, Chief Scientist of BTG Labs, contributed to the most recent issue with an article entitled, “Film surface properties: Techniques for measurements and control of treatment level.”
The success of print quality and adhesion quality of films relies on precise control of the surface. Manipulating surface composition with methods such as flame, corona, and plasma treatment can increase surface energy and thus improve the integrity of print and adhesion on film. …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.
Contrary to popular belief, print isn’t dead: at least not printed packaging, an industry growing to a worth of $8 billion of the $20 billion global print market.
The printed packaging market is booming. As with any growing industry, manufacturers must work vigorously to produce the best product and continue developing better ones.
Some of the newer developments include smarter surface processes. Que BTG Labs. When it comes to surface processes, we’re in our element. As experts in materials science, we have the ability to optimize critical surface processes for manufacturers—including printed packaging.
Any printing involves critical surface processes including supplier quality check, surface treatment, verification, shelf life, and trouble shooting.
The Surface Analyst improves these areas of printed packaging. This surface cleanliness gauge determines the quality of incoming product; sets or optimizes specifications; verifies surface treatments such as corona and flame; determines the shelf life of the material after treatment; and trouble shoots printing issues.
