Henkel Releases New Structural Bonders to Address Maintenance Industry Costs

Posted By ASC, Thursday, August 3, 2017

Henkel has introduced new structural bonders that the company reports combine the benefits of epoxy adhesives with those of instant adhesives and structural adhesives. They are designed for general-purpose repairs, and as such, they are able to form strong bonds across a wide range of substrates including plastics and can tolerate demanding operational conditions.

 

Loctite HY 4070 adhesive allows for rapid bonding and maintains bonds when subjected to a wide range of temperatures, according to Henkel, as well as offering chemical resistance and resistance to humid conditions. It performs well when used to bond metals, rubber, and most plastics. It has been released along with Loctite HY 4060 GY, a general-purpose adhesive that cures in just five minutes. Like its relative in the Loctite range, it is able to form high-performance bonds across a wide range of substrates.

New Electronics Assembly Adhesive from Dow Corning for OEMs

Posted By ASC, Tuesday, August 1, 2017

With electronic devices becoming important features in today’s newest cars, OEMs have been seeking adhesives that can tolerate harsh environments, provide robust bonds, cure quickly at relatively low temperatures, and bond a variety of substrates reliably. Dow Corning’s new EA-5151 Quick in Connect (QiC) Adhesive seeks to address these issues.


The one-part silicone adhesive is designed for use with plunger driven applicator guns or robotic applicators and delivers instantaneous green strength, allowing components to be handled immediately after the adhesive has been applied. The bonds will cure fully thanks to exposure to ambient humidity within three days at room temperature, but if heated to between 120°C and 130°C before 24 hours have passed, the adhesive can be removed, allowing manufacturers to reassemble components if necessary.


Dow says that its newest adhesive is flexible, offers shock, and impact resistance, and will provide manufacturers with a cost and energy efficient solution that compares favorably with earlier adhesives and double-sided tapes.

New Sealant Allows Historical Buildings to be Energy Efficient Yet Remain Authentic

Posted By ASC, Monday, July 31, 2017

Historical buildings add charm and character to any landscape, but they may not be very energy efficient. Now, a new sealant, Hotver A+, will allow the custodians of these architectural gems to improve energy efficiency through better insulation of glass surfaces without affecting the authentic appearance of windows.


SafeGuard, a UK manufacturer of insulating glass units will apply sealant technology developed in partnership with the Fenzi Group to its units, allowing historic buildings to reach energy efficiency targets in line with the EN1279 standard. This requires low gas leakage and moisture penetration. Previously, it was not possible to achieve this owing to the narrower space for glazing available in old buildings which did not allow for the installation of energy-efficient glass.


To ensure that the sealant would continue to perform well for extended periods, the Fenzi Group tested samples of the insulating glass, and the company says that its product will provide a long-term seal that will limit the need for further work on historic buildings after it has been installed.

Dow Introduces New Food Packaging Adhesive for Medium-Barrier Applications

Posted By ASC, Thursday, July 27, 2017

Dow Chemical Company has announced the release of a new food packaging adhesive which the company says will confer several advantages to food packaging companies. It has been designed for resource efficiency and to enhance the recyclability of flexible packaging by enabling the use of polyolefins instead of metalized packaging, aluminum-based packing, or PET. Dow says that the advance will meet the demand for cost-competitive, recyclable packaging while still optimizing shelf-life.

 

When used in medium-barrier applications, the company reports that the product will not adversely affect the shelf-life of packaged foods and may even provide a better seal, excluding oxygen and moisture more effectively. Meanwhile, food packaging companies will be able to enhance their sustainability profiles by supplying products in packaging that is compatible with existing recycling techniques.

Adhesive Backed Floor Mats Improve Safety in High Traffic Retail Areas Subject to Spills

Posted By ASC, Wednesday, July 26, 2017

Mats can easily slip and slide, and in areas where spills are likely, moisture can pool and be tracked to other areas. Traditionally, the solution has been to provide absorbent mats with a rubber backing, but these mats tend to curl at the corners, may become bunched up, and can still move about. The solution from New Pig, a company that specializes in leak and spill protection equipment, is called Grippy Mat, and it overcomes these problems by using an adhesive instead of a rubber backing.


The matting is designed to protect floors from moisture. It can remain in place while being buffed or mopped and has NFSI certification as a high-traction, rip, shred, and fray-resistant floor covering. The P53 adhesive used as a backing keeps the matting firmly in place while the upper layers eliminate pooling of liquids when spills occur. Business owners can leave these mats in place for twelve weeks at a stretch, saving maintenance and matting hire costs.

Adhesives.org BLOG: Off-Site Construction is Changing the Work

Posted By ASC, Tuesday, July 25, 2017

BLOG:  Off-Site Construction is Changing the Work
 
By Paul Bertram, Adhesives.org Expert Blogger

Owners, Architects, Engineers and Contractors in both commercial/industrial and residential housing markets are seeing increasing Off-Site Construction system integration. This is changing the work process as related to components that make up systems including adhesives and sealants. The functional performance requirements are the same but with skilled labor shortages Off-Site construction fabrications including mechanical and electrical systems are offering higher quality control, fewer construction defects, faster build speeds.


The National Institute of Building Sciences defines "Off-site construction" as the planning, design, fabrication and assembly of building elements at a location other than their final installed location to support the rapid and efficient construction of a permanent structure. There are many variations of Off-Site Construction including: Prefabricated, Permanent modular construction, Unitized modular and construction.


Manufacturers, suppliers and subcontractors’ businesses are being impacted as more Off-Site construction is adopted in lieu of Site Built Systems. It requires culture changes to address their customer bases. Off- Site Construction does not totally eliminate Site Built applications of Adhesives and Sealants but is impacting the amount of that work.


Adhesives and sealants are being applied in Off-Site prefabricated systems in a controlled environment by trained laborers for consistent performance and require a different solution from suppliers. When these systems come to the job site for final installation on site use of adhesives and sealants is necessary to “marry – up” the multiple systems. An example would be...

Airbus to Use 3D-Printed Polymer Jet Parts

Posted By ASC, Wednesday, July 19, 2017

Airbus, with its supply partner Stratasys Direct Manufacturing, will use 3D-printed polymer parts for use on its A350 XWB passenger jet. The Stratasys will print non-structural, installation parts such as brackets with ULTEM 9085 material. This particular resin has become popular in aerospace due to its flame-retardant characteristics and high strength-to-weight ratio.

Airbus feels the use of 3D printed parts will help it cut costs and improve supply chain flexibility, due to the quicker turnaround times on parts. The lower weight of the parts could also improve fuel efficiency and passenger jet performance. Airbus also believes the nature of 3D printing will allow for producing and shipping parts in an on-demand fashion, thereby lowering inventory costs.

Stratasys and Airbus have had a working partnership in place since 2013. Since 2015, Airbus has installed thousands of FDM (Fused Deposition Modeling) flying parts on aircraft.

Flexible New “Superglue” Created in Quest for a Rapid, Efficient Bonding of Hydrogels

Posted By ASC, Tuesday, July 18, 2017

Hydrogels are increasingly being used in electronics manufacture, but this calls for adhesives that can from strong bonds that can flex with the hydrogel. In a quest for a rapid, efficient way to bond hydrogels, researchers have achieved a flexible “superglue” by adding a non-solvent to a Cynoacrylate adhesive. The non-solvent allows the adhesive to disperse into the hydrogel forming a deeper bond instead of a superficial one.

 

The Cyanoacrylate component bonds when exposed to the moisture in the hydrogel while the nonsolvent prevents it from hardening and becoming brittle while allowing for the deeper bond. The research team has tested its innovation by creating an electronic skin that was able to communicate data to a smartphone.

 

They also tested the adhesive on artificial vertebrae made from hydrogel. These may be used in future to replace worn-out spine discs. Assembly was much quicker using the prototype adhesive. In addition, the research team believes that the new adhesive will be useful in soft robotics, allowing robotics experts to affix sensors to flexible surfaces.

EPA to Accept Nominations for Science Boards

Posted By ASC, Monday, July 17, 2017

The U.S. Environmental Protection Agency published a notice in the Federal Register seeking nominations for the Science Advisory Board (SAB) and Clean Air Scientific Advisory Committee (CASAC). Nominations will be accepted until July 27, 2017. Members serve at the request of the Administrator and are carefully selected for their scientific expertise and independence.

“These boards play an important role at EPA by providing independent advice based on sound science in support of the agency’s mission, and I would like to thank all board members for their service,” said Administrator Pruitt. “I strongly encourage scientific viewpoints from a full range of stakeholders in order to achieve balanced scientific advice.”

In 1978, Congress directed EPA to establish an SAB to provide independent scientific advice to the Administrator on science that underlies agency rulemaking.

As spelled out by the Clean Air Act, CASAC has specific statutory duties, including advice related to air quality standards like the National Ambient Air Quality Standards (NAAQS). A recent Government Accountability Organization report found that CASAC has never provided advice on adverse social, economic or energy effects related to NAAQS because it was not asked to play that role. Moving forward, EPA will ensure the CASAC addresses this serious deficiency and fulfills its complete duties, as spelled out by legislative statute...READ MORE
