Researchers Uncover the Secret Behind Ivy’s Natural Adhesive Paving the Way for New Biomimicry Advances

Posted By ASC, Monday, June 20, 2016

Charles Darwin was the first to observe that Ivy exudes a liquid adhesive that helps it to cling to surfaces. Now researchers at Ohio State University have identified the protein that allows Ivy to stick. Nanospherical arabinogalactan proteins (AGPs) allow Ivy’s adhesive to enter nanoscale openings rather than just coating surfaces.Curing takes place due to calcium-driven electrostatic interactions among carboxyl groups of the AGPs and pectic acids. As water evaporates from the adhesive, chemical bonds are formed between adhesive and substrate.


The researchers say that their discovery opens up the possibility of applying its findings to the development of adhesives for a wide range of applications ranging from medical adhesives to coatings and even cosmetics. To test their hypothesis, the researchers created a basic adhesive using ivy nanoparticles combined with pectic polysaccharides and calcium ions. The prototype adhesive could form the basis for future high strength adhesives and coatings and may allow for the development of engineered scaffolds for use in tissue engineering and regenerative medicine.

New Solvent Free Lamination Technology from Dow and Nordmeccanica

Posted By ASC, Thursday, June 16, 2016

Dow Packaging and Nordmeccanica have announced a new lamination technology that combines new machinery with new adhesives. The newSYMBIEX™ Solventless Adhesives cures rapidly, and can be used in conjunction with Nordmeccanica’s Duplex SL One Shot™ lamination line. The announcement follows the collaboration agreement between Dow and Nordmeccanica 18 months ago.


The companies say that their combined innovations will improve efficiencies, reducing time to market and conversion costs. Laminations can be slit after 90 minutes compared to the current standard of 24 hours. Additional benefits include the elimination of pot life and mixer concerns, reduced production line downtime and curing inventory, the ability to use laminated materials in less than a day while still achieving food compliance, the elimination of misting and improved wettability, no adhesive wastage, easier equipment cleaning, and the ability to perform quality control checks within 30 minutes of lamination.


The new laminating equipment ensures that the two component adhesive only begins its chemical reaction at the lamination nip station. This means that no mixing unit is needed while pot life issues are eliminated. As a result, machines require less downtime and are easy to clean.

ASTM Proposes Standard to Determine Sealant Longevity

Posted By ASC, Wednesday, June 15, 2016

The ASTM Committee C24 on Building Seals and Sealants is in the process of developing a standard that aims to make accelerated sealant design life testing possible for makers of joint sealants used in the construction industry. The resulting guide, WK48490, Practice for Developing Accelerated Tests to Aid Prediction of the Design Life of Sealants, will set out the steps that need to be followed for accelerated sealant testing procedures.


ASTM commented that it is important to determine just how long sealants will last under real conditions, but that accelerated design life testing will be needed. The new standard will deal with the testing of sealants used for building insulation and water-proofing. He believes that the protocol will be helpful to companies that are developing new sealant products and systems for the construction industry.


ASTM says that participation from the sealants industry is welcomed during the formulation of standards such as this.

Automotive Manufacturers Turn to Injection Bonding of Composite Adhesives for Carbon Fiber Inlays

Posted By ASC, Tuesday, June 14, 2016

Carbon fiber components are changing the way cars are manufactured as the adhesives industry comes up with bonding solutions that make engineering ideas workable. Injection bonding of composite adhesives allows manufacturers to insert carbon fiber parts as inlays in the metal housing that runs along the A-pillar and down the D pillar. This increases occupant safety during side-on collisions or if the car were to roll. It also improves the torsional stiffness of the vehicle, improving vehicle handling.


Because carbon fiber and metal have different Coefficients of Linear Thermal Expansion (CLTE), adhesives such as DowAutomotive’s BETAFORCE, with its high elongation factor and modulus provide sufficient stiffness while still being flexible enough to tolerate differing CLTE. In order to bond carbon fiber inlays to metal, a robot injects the adhesive, surrounding the carbon fiber. Dow is currently assisting BMW with its lightweighting efforts and says that it develops products and techniques according to its clients’ requirements.

ASC CELEBRATES SENATE APPROVAL OF TSCA REFORM

 


June 10, 2016 – Bethesda, MD – The Adhesive and Sealant Council (ASC) applauds the Senate’s passage of legislation to reform the decades-old Toxic Substance Control Act of 1976 (TSCA). The Senate voice vote under unanimous consent necessitates only President Barack Obama’s signature for the measure to become law.

ASC has been a leading advocate of TSCA reform for more than eight years and a founding member of the Alliance for American Innovation, a coalition of trade associations representing a broad spectrum of the economy dedicated to creating a more transparent and evidence-based chemical review program.

“The widespread support for this legislation is testament both to the urgent need to update U.S. chemical safety laws and the ability of Congress to still be able to come together to solve important problems facing our country,” said Mark Collatz, ASC’s Director of Regulatory Affairs. “The compromises worked out through the Frank R. Lautenberg Chemical Safety for the 21st Century Act will restore a regulatory framework that protects human health and the environment, while providing a greater regulatory certainty for chemical manufacturers and their down-stream customers such as adhesive and sealant manufacturers.”

“The Council looks forward to working with the Environmental Protection Agency (EPA) in the coming months as they begin the rulemaking process to implement this historic measure,” said Collatz.

Trends to Consider: Driverless Cars and Traffic

Posted By ASC, Thursday, June 9, 2016

A recent report on the driverless car reports that these cars can navigate safely under most conditions and could become available in the next 5 to 10 years, and driverless cars that can handle all sorts of conditions should be on the road in 10 to 20 years. Because cars will be able to drive kids to school, pick up groceries and help disabled or elderly people get around more easily, experts believe that the number of miles driven and the number of cars on the road will increase.


Last year, a total of 3.1 trillion miles was covered by drivers in the US. With autonomous cars ferrying kids and senior citizens from place to place, that distance will increase by a further 2 trillion miles per annum. If people start sending driverless cars to run errands by themselves, the increase in distance traveled could be as much as 4 trillion miles.


Driving will be less risky and less costly. Driverless cars will reduce traffic accidents and insurance will be cheaper. The time that people using these cars will save and be able to use productively will be the biggest cost-saving factor. A study in the journal of Transportation found that driverless cars will cut travel costs by up to 80% when this factor is taken into account. But the researchers warn that with easy, cheap travel at their fingertips, car owners will travel more miles than ever before.


Many believe that despite this, traffic congestion will be reduced because of safer, faster travel and fewer accidents. But these benefits will only be realized when driverless cars are widely adopted. Some experts say that commercial carpools consisting of driverless cars that can be summoned on demand are the answer. These cars could transport several passengers who are travelling in the same direction on any given trip.


On the other hand, if half the cars on the road are still conventional cars, miles traveled will increase by 30 – 90% even if driverless car sharing is adopted. Policy changes that disincentivize the use of private cars may have to be adopted, and even land use policies may have to change to prevent people from moving out of urban centers owing to easy and fast commuting.

Aerosol Foam Sealants Standard Proposed by ASTM

Posted By ASC, Wednesday, June 8, 2016

ASTM’s Committee C24 on Building Seals and Sealants is currently developing a guide that will be used internationally in order to assist designers and consumers in choosing the most suitable aerosol foam sealants for projects. The standard would distinguish between sealants based on the areas in which they would be used, namely: windows, doors and skylights, where they would be applied as a secondary seal, fire blocking and gap sealing, and adhesive foams used as drywall or subfloor adhesives and for structurally insulated panels and insulated concrete forms.


The organization says that its new standard would help designers and consumers to understand the wide variety of foam sealants currently available on the market allowing them to make better material choices. The guide will also highlight the energy cost savings that can be achieved through the use of aerosol foams. An easily understandable format using pictograms will demonstrate the ways in which foam sealants can be used. Different types of dispensing mechanisms, and typical can sizes will be explained. The subcommittee is inviting expert input related to foam sealants’ movement capability and its measurement.

New Liquid Gel Adhesive Cures Instantly on Exposure to Electric Current

Posted By ASC, Tuesday, June 7, 2016

Researchers at Nanyang Technological University in Singapore have announced the development of a new, low viscosity liquid gel adhesive. The adhesive can be applied with precision, and curing is activated by exposure to electric current. By varying the voltage and duration of the current, the adhesive is exposed to, adhesion can be fine-tuned.


The new adhesive can be used in medical device manufacture as well as in automobile and consumer goods production. There are also biological devices for which adhesives that are cured using heat or light are unsuitable or difficult to use. These include bioelectronics and polymer electronic devices that are attached to living tissue.


The bonds formed using the new adhesive are strong, and demonstrate high sheer strength while providing a high degree of elasticity. The tunability of the adhesive will allow it to handle specific vibration frequencies and create bonds that match the flexibility and firmness of living tissues.
