Sealant Ensures Happy Landings for Air Traffic

Posted By ASC, Wednesday, April 20, 2016

Airport runways and parking aprons handle heavy traffic and all kinds of weather. Inevitably, the wear begins to tell, with cracks and joints needing sealing to keep airplane traffic running smoothly and safely on the ground. A new caulk has been developed by Ultimate Linings Ltd that resists jet fuel spills and harsh weather conditions to help ensure smooth landings and cut down on costly maintenance.

 

UL Caulk-JF is a non-toxic polyurethane calking sealant that is applied using a straightforward pneumatic gun and could help address the wear and tear problems faced by the 19,000+ runways around the United States. After a costly development project, the scientifically developed product has achieved Federal specification SS-S200E, the necessary ‘green light’ that certifies it as a safe solution for airfield applications. The caulk has been made available in a variety of packaging sizes, ranging from a 750ml cartridge to a 250 gallon tote.

New Hot Melt Adhesive Strand Coating System Nominated for Award

Posted By ASC, Monday, April 18, 2016

An innovative device from Dynatech, the Ultra Strand Coating System, now allows for greater efficiency in coating elastic strands with adhesives. The device is designed for use in the disposable personal hygiene sector and allows for faster processing times amounting to 1,400 pads per minute. In addition, a Rapid Change Over feature will speed equipment maintenance processes, while Ultra-stich and Ultra-touch nozzles match various manufacturers’ requirements.

 

Optimal device lifespan, production line efficiency and the application of the least possible volume of adhesive have all been taken into account. Total creep strength has been reduced to 1%, and the larger nozzles are less likely to block, causing production line hold-ups. The equipment was developed using computational fluid dynamics technology, and has been nominated for an award by the Association of Nonwoven Fabrics Industry (INDA). Dynatech’s systems are implemented on a global scale, particularly in the manufacture of disposable diapers.

Carbon Fiber in Auto Manufacture: Too Costly or Material of the Future?

Posted By ASC, Thursday, April 14, 2016

Experts are divided in their opinions regarding the use of carbon fiber in auto manufacture. Critics say that the material is too costly when compared to aluminum and high-strength steel. They also observe that most body shops won’t know how to repair or replace the new materials.


On the other side of the debate, proponents of carbon fiber hail it as a ‘paradigm shift’ that will change the way cars are engineered. They argue that most repairs will be very simple, and that body shops will be able to repair or replace components with relative ease. The BMW 13 even has markings showing where the carbon fiber components should be cut away when replacements are needed.

 

As for the safety benefits of carbon fiber combined with adhesives, engineers are impressed. The new BMW i3 has a life module consisting of 90% carbon fiber and is constructed from nine molded parts. It has performed very well in crash tests in the EU, and US results are expected to be as favorable.


The use of adhesives to bond the body to its aluminum frame raised eyebrows, but this choice was vindicated by fruitless attempts to rip the body from the frame. Munro and Associates, whose company disassembled a BMW i3 RX down to the ball bearings (and is regularly contracted to do these teardowns for the industry), was blown away by the car’s engineering and implications. Ultimately, a vibrational cutter had to be used to slice through the epoxy and the whole process took a week. Munro senior associate Mark Ellis says that he will trust epoxy over spot welds from now on. Adhesives are also used to bond overlapping carbon fiber panels to the aluminum floor pan, eliminating galvanic corrosion and reducing noise.

 

However, the concerns regarding the cost of carbon fiber are warranted, and may limit or delay the widespread adoption of this material in vehicle manufacturing.

Research Advance in Customizable Drug Delivery Bioadhesives

Posted By ASC, Tuesday, April 12, 2016

Researchers at LSU are in the process of developing a new adhesive gel for drug delivery that will be more cost-effective than existing hydrogel-based carriers. A process dubbed a “pH clock reaction” is being applied after studies into the interaction between urea and the enzyme urease.  With the addition of two chemicals during the “clock reaction”, a water-soluble adhesive gel is created.

 

This gel, though similar to other delivery methods will offer cost-savings owing to the resulting ‘one-pot’ formula that does not require the use of polymerization catalysts or initiators. Thus, the bioadhesive can form in the human body without any external stimulus.

 

As the hydrogel degrades, the drug is released, and since this process is tunable, a high degree of customization and predictability becomes possible. Although the bioadhesive and its degradation products are completely non-toxic, researchers say that further work will be needed before the advance is market-ready.

Adhesive Dispensing Equipment Choices

Posted By ASC, Friday, April 8, 2016

Adhesives are playing an important role in innovation of consumer products, but the choice of the right dispensing equipment is as important as using the right adhesives. The materials to be bonded, requirements for curing, cure time and production line requirements are among the considerations to be taken into account.

 

Manufacturers are advised to discuss the materials that will be used, bond strength requirements and the operating environment in which adhesives must maintain their integrity with adhesives specialists. The volume of adhesives required and the accuracy with which they must be applied will also affect the choice of adhesives and their related dispensing equipment. Low flow, high volume machines dispense accurately over a longer time period, while high flow, low volume machines dispense large amounts of adhesive in short burts.

 

Manufacturing volumes also play a role. Bulk processing is generally more economical and allows for increased automation including robotics. In this case, options range from simple pneumatic circuitry to integrated PLC controls. System controls and interfaces should also be simple to use and allow for easy maintenance.

ASC CREATES PRODUCT CATEGORY RULE FOR SEALANTS

 

Member Task Force Drafts PCR; Seeks Industry Input



April 5, 2016 – Bethesda, MD – The Adhesive and Sealant Council (ASC) announced that it has created the first draft Product Category Rule (PCR) for Sealants for North America. The PCR sets the rules that industry should follow when conducting a Life Cycle Assessment (LCA), which is then used to create an Environmental Product Declaration (EPD). EPDs are tools that the value chain is beginning to use to communicate impact categories within the building and construction industry, and other industries.

The PCR for Sealants was created in a collaborative, consensus driven manner with an ASC member task force, UL Environment and Thinkstep. The draft PCR is now open to public comment as ASC strives to deliver an industry wide PCR for sealants supporting the North American market.

“PCRs are the first – and important step – in supporting the industry as we respond to an increase in customer requests for product information,” notes Matthew E. Croson, President of ASC. “The PCR will outline in detail how a company should approach an LCA when developing an EPD, and is a vital part of the EPD process."

Within the building and construction industry, some architects are asking for product information in order to gain points for the United States Green Building Council’s LEED program, specifically in the EPD credit worth 1 or a ½ point. In other parts of the world, EPDs are becoming an accepted mode of communications between materials manufactures and the design community. In Europe, both the IVK and FEICA – two of the leading organizations supporting the adhesives and sealants communities in Germany and the EU, respectively, have already developed PCRs and even model EPDs, to support industry.

“UL Environment is pleased to work with the ASC to issue this PCR, which will enable manufacturers of sealants to communicate their products’ environmental impacts so that purchasers can make more informed buying decisions,” said Anna Nicholson, Program Manager for UL Environment. “This PCR is a significant step and shows the industry's commitment to continued sustainability."

The PCR is now available for public review and comment until April 29, 2016 at http://bit.ly/1qlp2ev, after which it will be reviewed by an independent expert panel.

Comments to be submitted here: epd@ulenvironment.com

“I would like to recognize the dedication and leadership of Steve Rosenberg of Sika for leading this effort which was a long process. Anna Nicholson of UL Environment and Christoph Koeffler of Thinkstep also played key roles in the development process of the PCR,” noted Steve Duren, ASC Senior Director of Member Services. We also want to recognize members of our steering team who were instrumental in the heavy lifting on content and decision making; Dan Marvin and Chris Bierschank-Mapei, Shen Tian and John Brand of Covestro, Jennifer Prancing of Dow Corning and Steve Rosenberg of Sika. The ASC took time to consider all sides of the PCR effort, and considered all options before bringing the draft to industry."

The ASC Task force voted unanimously 15 to 0 to develop the PCR and was further authorized by the ASC Executive Committee in November of 2015. Through a series of conference calls and ongoing dialogue with both the steering group and full task force, the document was created.

ASC will host a series of four speakers on the PCR topic at its Spring Convention in New Orleans April 18-20, the full program can be reviewed here. More details and history of the PCR can be found in the upcoming ASC/ICIS convention magazine, which will be available onsite in New Orleans or you can preview the article here.
