Purdue Researchers Design Bioinspired Elastin Medical Adhesive

Posted By ASC, Thursday, March 16, 2017

Biocompatible adhesives that will form and maintain bonds in wet environments are important for medical applications and are exciting much interest in the research community. Researchers at Purdue University have announced their development of a new adhesive formula to address unmet needs for biomedical adhesives. The new formula can also be adjusted to meet a variety of needs thanks to its environmentally responsive properties. The adhesive material, ELY16 is made from a polypeptide that is similar to elastin, a protein found in connective tissue.

 

The underlying principles behind the adhesive match those used by marine creatures like mussels and sandcastle worms. The new material undergoes chemical reactions after exposure to enzymes, converting into mELY16 and 3,4-dihydroxyphenylalanine (DOPA). DOPA helps the protein to bond with glass with an adhesion strength of around 250 kPa. When compared to fibrin sealants, mELY16 exhibits significantly greater bond strength. The researchers have concluded that the new adhesive protein shows potential for further commercial development as a smart biomedical adhesive.

Adhesives.org BLOG: Imparting Barrier Properties in Flexible Packaging Application: Part 2

Posted By ASC, Tuesday, March 14, 2017

BLOG:  Imparting Barrier Properties in Flexible Packaging Application: Part 2

 

By Deb Bhattacharjee, Adhesives.org Expert Blogger

 

In an earlier blog HERE, the discussion centered on the fundamentals of barrier properties, how it can be best achieved in a practical and cost effective manner through judicious selection of multilayer polymer films necessary for success in a specific application.While most of the barrier properties to oxygen would come from the plastic layers, design of the polymer backbone in adhesive could also play a very important part in improving the barrier properties. This is quite intriguing as adhesives constitute a very small fraction (~1wt.%) of the total mass of the overall packaging material. The purpose of this blog is to discuss several approaches of improving barrier properties through modification in adhesives composition and incorporation of fillers.


These include:

 

  • Acrylic adhesive composition containing (meth) acrylate component and a cure system including naturally occurring filler (e.g. a tannin-containing cellulosic material, such as wood flour) which inhibits free radical cure, and oxygen scavengers like triphenylphosphine and phenyl dihydropyridine, was also reported to impart barrier characteristics in packaging applications (US8231758)
  • Epoxy hardener obtained by reacting m-xylylene or p-xylylene diamine with unsaturated carboxylic acid was claimed to have improved gas barrier properties (US20150082747)

AkzoNobel rejects $22 billion PPG bid, citing #DutchPride

Posted By ASC, Friday, March 10, 2017

Dutch paints and chemicals maker AkzoNobel NV on Thursday spurned a takeover offer by PPG, but the Pittsburgh coatings company said it will continue to pursue a deal despite political sentiment against foreign takeovers in the Netherlands.


PPG’s unsolicited bid for the Dutch company totals 21 billion euros ($22 billion), or about 83 euros per share, including 54 euros cash plus 0.3 shares of PPG for each Akzo share.
Akzo’s shares jumped by 13 percent Thursday to close at 72.79 euros while PPG shares fell by more than 3 percent to close at $102.93, down $3.90. PPG’s stock had surged Wednesday on news of the bid.


Akzo said the offer was too low and was reviewing its options, including the possibility of spinning off its chemicals business to boost its value.


“The unsolicited proposal we received from PPG substantially undervalues our company and contains serious risks and uncertainties,” Ton Buchner, Akzo’s chief executive, said in a statement.
“The proposal is not in the interest of AkzoNobel’s stakeholders, including its shareholders, customers and employees, and we have unanimously rejected it.”


Securities analysts said it’s likely PPG will increase its bid and could possibly structure a friendly offer for Akzo.

Frogs Hold the Secret to Reversible Adhesives for High-Speed Application

Posted By ASC, Wednesday, March 8, 2017
Nature has been an inspiration for many scientific and technical advances, and now frogs may be pointing the way towards yet another advance in adhesives technology. In a recent discovery, frog saliva has been found to act as a non-Newtonian fluid that can act as both a liquid and a solid. This adhesive tolerates forces twelve times that of an object’s gravity, allowing frogs to catch creatures nearly one and a half times their body weight.

The frog’s viscous saliva liquefies on contact solidifying instantly to form a bond that penetrates every crevice on a surface. The action of the tongue itself also plays a role, absorbing energy and ensuring good coverage on the surface it contacts. Then, the tongue retracts, and the frog saliva slips off, allowing the frog to swallow its prey. The combined action of tongue and saliva result in adhesion that is fifty times greater than that of current synthetic polymer materials and could become the principle behind reversible adhesives for high-speed application.

Adhesives.org BLOG: Let’s Define “Structural Joint”

BLOG:  Let’s Define “Structural Joint” – to Ensure the Integrity of the Joint Design and Bond

 

By Dan Daley, ChemQuest, an Adhesives.org Expert Blogger

 

Let me start by introducing myself and my colleague, James Swope, at the ChemQuest Group, Inc., as new contributors to the ASC Blog. In 2017, we will discuss adhesive and sealant technology for use in transportation applications. Jim and I are both excited to be contributing posts on topics that are relevant to adhesives’ end users and tap into our working knowledge – having spent decades in our previous roles – at formulating and end-use companies, respectively. In our current roles, identifying unmet market needs is central to nearly every ChemQuest project in which we are engaged, especially on behalf of automotive tier suppliers and their end customers.


A buyer or user of adhesives – who is new to adhesives technology – might want to learn all they can about chemistries, resin types, application methods, performance properties, dissimilar substrates, vendors and formulated products on the market. In our discussion of blog topics, we found that even our most experienced colleagues had different opinions as to the meaning of “structural bonding” or “structural joint”, which can and does lead to intriguing discussions.


While the word “structural” might conjure up images of “strength” for many people, Merriam-Webster Dictionary’s definition of “relating to the way something is built or organized, ”certainly resonates with me as a materials engineer. The durability and integrity of the structural joint is completely dependent on how expertly it is designed and organized: Materials and their properties are a factor as well as...Read More

Thermal Imaging Helps Chemicals Company to Monitor Package Sealing Quality

Posted By ASC, Thursday, February 23, 2017

Recochem Inc., a Canadian manufacturer of chemical products and fluids, needs to ensure that its products are effectively sealed in the packaging process to safeguard product quality and safety. It distributes windshield fluid in jugs packaged within cartons with an overwrap. The cartons are sealed with a hot-melt adhesive, and Recochem needs to check that the adhesive has been correctly applied. To do this, the company is using thermal imaging using an FLIR AX8 thermal imaging camera.


The camera can “see” through the carton, checking adhesive spot sizes and temperatures. The thermal images show the higher temperature areas where the adhesive has been applied. If there is a problem with the glue gun, the hotter spots form a different pattern, alerting a technician who monitors the images. Previously, quality controllers would choose and destroy a random box every 10 to 15 minutes so that it could be inspected, but now, both the time needed for this and the waste of cartons has been eliminated from the packaging line. The company says that the resulting time and money savings are significant.
