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
BTG Labs will present new data on monitoring laser cleaning with Surface Analyst at ALAC (Advanced Laser Applications Conference) 2017. Taking place in Novi, Michigan from May 9-10, this show brings together the latest in advanced laser technology.
BTG Labs’ Lead Sales Engineer Lucas Dillingham will present a paper entitled, “A New Technology to Develop, Monitor, and Validate Laser Cleaning Processes” at 10:00am on May 10. Verifying the effect of laser cleaning on metal surfaces has proved challenging, especially on the manufacturing floor. This paper showcases new data on using the Surface Analyst to monitor and optimize laser cleaning processes on metals. The Surface Analyst’s portability allows for its use directly on the manufacturing floor to objectively verify laser cleaning on every part. Knowing the quantitative outcome of a laser cleaning application allows optimization to produce a more reliable final product. The Surface Analyst is the ideal way to verify laser cleaning processes quantifiably and precisely right on the factory floor. …Read More
It’s the first day of spring. Depending on where you live, this could mean opening the windows, planting seeds, rolling out the motorcycle, and waiting for Opening Day. Here at BTG Labs, we think of spring cleaning. Of course, this usually generates visions of humming vacuums and sloppy mops, but we see whooshing parts washers and smooth solvent wipes. Why? Well, because our instrument, the Surface Analyst is a significant player in the cleaning game.
The Surface Analyst is the keystone to verifying, troubleshooting, monitoring, and even choosing a cleaning process.
A cleaning method is only as useful as it’s verification process. In under two seconds, the Surface Analyst measures water contact angle to determine surface cleanliness. The instrument can be programmed to produce a pass/fail result based on the manufacturer’s specifications. This is an easy, objective method that immediately assures the technician of the surface cleaning process.
Furthermore the Surface Analyst can be used to choose the most efficient cleaning method and optimize existing cleaning methods. Sometimes a particular solvent is more effective than another or the water in a parts washer becomes dirty. The Surface Analyst helps detect these elements to ensure the process is running flawlessly.
Lastly, the Surface Analyst helps manufacturers choose the best cleaning method for their manufacturing process. In most scenarios, the only way to test a cleaning process is in the field or the laboratory. This is time consuming and causes failures and waste. The Surface Analyst, on the other hand, tells the user right on the factory floor, whether or not the part has been properly cleaned to bond, print, seal, coat, or paint without out wasting time or material. …Read More
The world of consumer goods is highly diverse so consequently, manufacturing processes are even more varied. From golf clubs to paints to windows to solar panels, consumer goods products face a variety of stresses in the field that can include moisture, impact, contaminants, and environmental stresses. Manufacturers must produce a product to withstand those stresses. BTG Labs’ Surface Analyst™ can do just that. It is a versatile, handheld, accurate, easy to use instrument that can cut down on failure and waste and ensure surfaces are properly prepared to create the strongest bonds whether its coating, printing, painting, sealing, or cleaning. The Surface Analyst measures, monitors, and guarantees from the lab to the factory floor.
