Akron Ascent Innovations (AAI) Partners with Velcro for Launch of New Dry Adhesive

Posted By ASC, Wednesday, February 1, 2017

When insects or geckos cross a surface, they leave no traces behind. Now Akron Ascent Innovations (AAI) has developed a dry adhesive that the company reports can stick to almost anything without leaving a residue. The new adhesives have strong shear adhesion but a low peel strength and very minimal tackiness. Peel them away from surfaces, and there’s no stickiness left behind according to the company.

 

AAI’s president, a senior research fellow at Akron University, says that the newly announced partnership with Velcro will help AAI to market its product much more effectively. Velcro sees a market opportunity for the adhesive in interior decoration. Pictures and hangings can be attached to walls using Velcro, and a dry adhesive backing will, in turn, attach the Velcro to the surface of walls or windows.

 

The versatility of the adhesive is demonstrated by its ability to bond with a wide variety of substrates including plastic, glass, steel, and drywall.  Further uses in the packaging, personal care, automotive, medical and construction industries are being explored. It’s first use, however, seems likely to stem from Velcro’s concept, and the resulting product is expected to be available by the end of 2017.

Louisiana Multi-Functional Materials Group Receives NSF Grant for New Sealant Technology

Posted By ASC, Tuesday, January 31, 2017

Louisiana Multi-Functional Materials Group has received a $225,000 research grant from the National Science Foundation (NSF) through the LBTC for the development of two-way shape memory polymers that can be used as sealants. It hopes to develop a cost-effective sealant for expansion gaps and for cracks in paving or bridge decks. The National Science Foundation reports that such a sealant would also be helpful in the construction and maintenance of harbors, buildings, domestic paving, swimming pools and more.

 

Although a variety of sealants has been used for this type of application, the group notes that most fail to seal cracks and joints properly because they expand when heated and contract when cooled. The new sealant would behave in the opposite way, expanding when cooled and contracting when heated. This would limit the thermal movement of jointed structures during extreme weather conditions, limiting damage and the need for repairs and maintenance.

 

The grant was awarded in December 2016 as part of the NSF’s Small Business Phase 1 Program, and the end date is estimated to be 31 August 2017.

W.F. Taylor and Spray-Lock Team up in Marketing Alliance

Posted By ASC, Monday, January 30, 2017

W.F. Taylor and Spray-Lock have announced their plans for a joint marketing initiative in which they will market each other’s product ranges along with their individual product offerings. W.F. Taylor specializes in trowel-applied adhesives but feels its clients will benefit from Spray-Lock’s spray-on adhesives in certain circumstances, and Spray-Lock will now be offering its clients W.F. Taylor’s products when they are better-suited to their requirements. Thus, both companies will have an extended product range and will be equipped to serve a wider customer base.

 

Taylor’s CEO commented that construction industry professionals would now have one-stop access to environmentally-friendly adhesives that will meet their needs despite installation variables. According to Spray-Lock, the alliance will help its clients find the best-fit product quickly, leading to greater efficiency. Both companies confirmed that the alliance is not a merger but a marketing alliance that will promote synergy in the supply of adhesives and the development of new products.

Nordson Releases a New Hose to Combat Adhesive Degradation and Downtime

Posted By ASC, Wednesday, January 25, 2017

Nordson has announced the release of a patent-pending hose that will reduce downtime for businesses using its equipment to apply hot melt or standard adhesives. The hose prevents adhesive degradation, reducing downtime as a result of clogged nozzles and ensuring that adhesives applied will be free of contamination that affects performance and final product quality.

 

The company says that its PureFlow hose is expected to have twice the life-span of regular hoses. It can be used to replace the Blue Series hoses which, though they had a long life-span, are nevertheless not as long-lasting as the new innovation. PureFlow hoses will be manufactured in the same standard lengths and will have the same flexibility as Blue Series hoses. RediFlex II hangers are included with the hoses. The hoses can be used without RediFlex II frame mounts, but if Nordson clients wish to make use of the hangers, the parent machine can be equipped with mounts.

New Polyolefin Sealant Released by Jindal Films

Posted By ASC, Monday, January 23, 2017

Jindal Films Europe has released its new SealTOUGH technology, a coextruded packaging film that is intended as a replacement for lamination with layers of sealant, or mono-web layers in packaging. The company says that its new product offers puncture resistance and enhanced clarity with improved modulus and seal strength and that the sealant film will allow a 30 to 40 percent reduction in gauge, contributing to reduced materials requirements and costs while remaining recyclable.

 

The company reports that the new packaging film has three times as much tensile strength and twice as much resistance to puncturing and impact as traditional materials. Clarity is as great as that offered by BOPP, but seal strength is as great as that of blown PE reports Jindal.

 

Jindal Films will be relocating its head office to LaGrange, Georgia, and the Georgia production plant is undergoing upgrades to increase its production and product range capacity. These improvements include the addition of orientation, metalizing, coating and slitting capabilities.

Adhesives.org BLOG: Imparting Barrier Properties in Flexible Packaging Applications

BLOG:  Imparting Barrier Properties in Flexible Packaging Applications

 

By Deb Bhattacharjee, Adhesives.org Expert Blogger

 

Each layer in multilayer flexible packaging serves unique property for the benefit in its end use application, esp. for improving the shelf life of the packaged goods. The packaging material needs to be versatile enough to withstand handling process forces maintaining physical integrity, resistance to chemicals, and suitable for barrier properties to several gases (e.g., O2, N2, CO2, moisture vapor). The driver and trends of barrier materials for flexible packaging, including functionalities and global volumes of barrier materials like aluminum foil, PET film, nylon resins, metallized films, PVDC resin, EVOH resin, transparent oxide-coated film, COC (cyclic olefin copolymer) resin, AMAB (acrylonitrile-methyl acrylonitrile copolymer grafted with butadiene) resin, etc. are described in details in the recent article, “Barrier materials for flexible packaging”, Market Focus Research – 2011 to 2015, by Allied Development Corp.


What are the fundamental properties determining the difference in barrier properties?

Barrier properties are correlated to the intrinsic structure of the polymer such as degree of crystallinity, crystalline/amorphous phase ratio, nature of polymer, orientation, thermal and mechanical treatment before and after food contact, polarity of chemical groups present into the polymer, degree of cross-linking, and glass transition temperature. Furthermore, the intrinsic composition of the packed food...READ MORE

Pioneer Adhesive’s Epoxy Clay Used to Mend Coral Reef

Posted By ASC, Tuesday, January 10, 2017

Fixing coral reefs with the help of adhesives may sound strange, but it is a reality. Pioneer Adhesive’s epoxy clay is being used for the job, in which divers affix coral fragments to bare rock in the hope that the living coral will grow and regenerate the threatened coral reef. The fragments are grown in special coral nurseries before being taken out to sea where divers first clean rocks, and then attach the coral using a combination of nails, zip ties and the epoxy clay.

 

The project is sponsored by Pioneer Adhesives Foundation Inc. in cooperation with local government and Pangasinan State University in the Philippines. In a single dive expedition, five teams of divers consisting of five divers per team will plant up to 2,500 coral fragments. Meanwhile, onshore efforts to support the establishment of the coral have been underway with volunteers planting mangroves to prevent sedimentation.
