3M's New Adhesive Tape for Extended Wear Adhesion of Medical Devices

Posted By ASC, 18 hours ago

3M has added a second wearable adhesive tape for use with medical devices to its product range. The new nonwoven, water-resistant adhesive tape can stretch in any direction, is breathable, and has a wear time of up to 14 days. The company says that the new tape was developed based on client requirements for an adhesivethat would reduce costs and increase patient comfort by allowing medical devices to be worn for longer. According to 3M, the longest wear for medical tapes of this kind up till now has been around ten days.


Thanks to its new tape, 3M hopes to help its partners and their patients by reducing the number of times medical devices must be removed and reapplied every year. The company is also satisfied that the tape can be peeled off without damaging skin.


3M says that it plans to further extend its range of adhesive tapes for use with medical devices until it is able to offer a “family” of tapes with different properties that will suit a variety of medical device requirements.

Highlights of US General Services Administration - GSA’s 2018 report: The Impact of High-Performance Buildings

Posted By ASC, Monday, October 15, 2018
Updated: Friday, October 12, 2018

Adhesives.org Blog from Paul Bertram...

 

This report demonstrates how “GSA’s high-performance buildings save energy, save water, cost less to operate, produce less waste, and have more satisfied occupants compared with typical buildings.”

To better understand Federal Policy in the areas of High Performance Buildings it is helpful to review agency, policy hierarchy and reference standards.

In December of 2007 Congress authorized the Office of Federal High Performance Buildings under the Energy Independence and Security Act (EISA) . The Office works to promote, coordinate and stimulate efficient building across the entire Federal government; that includes 400,000 owned and leased buildings containing over 3 billion square feet of space.  Various Executive Orders regarding requirements for Federal buildings evolved from ESIA.

GSA Hierarchy of Polices, Committee Structure, Guiding Principles, Standards and Tools for High Performance Buildings... SEE ILLUSTRATION



Key Findings of the Report
The study included 200 buildings over a three-year period, and is the first to combine an internal analysis of GSA buildings with comparisons to industry-accepted benchmarks

GSA is leveraging the results of this study to promote cost savings, technology advancement, and operational excellence in our nation’s federal buildings. Data collection efforts and publications of these findings are intended to demonstrate how federal, state and local agencies as well as the private sector can understand the benefits of tracking building performance and using the resulting data to drive building-and portfolio-level decisions.

Note: “In this study, high-performance buildings are federally-owned, GSA-managed buildings that meet the Guiding Principles for Sustainable Federal Buildings. Legacy stock buildings are federally-owned, GSA-managed buildings that have not been upgraded to meet the Guiding Principles.”

Data for five metrics were collected...

New Cycle Tire Sealant Injector Prevents Blocked Valves

Posted By ASC, Friday, October 12, 2018

KOM Cycling has announced the release of its new Tubeless Sealant Injector. Instead of fitting over the tire valve stem as other sealant injectors did in the past, it fits inside the Presta valve after removal of the valve core. This means that less sealant spills or drips during injection, and because the design bypasses the valve core, injecting the sealant directly into the tire, there’s less chance of the valve becoming blocked.

 

Consumers who purchase the injector are also supplied with a valve core removal tool. KOM cycling says that its injector is compatible with most sealants on the market today.

Master Bond Inc Introduces New Adhesive for Electronics and Electro-Optics

Posted By ASC, Thursday, October 4, 2018

New Jersey-based Master Bond Inc has launched a new thermally stable two-part epoxy adhesive to be used in bonding electronic and electro-optic components. The adhesive, E70CN, will be used by OEMs and the aerospace industry.  The company says that the formulation is environmentally friendly, exhibits a high degree of physical strength and can be used for coating, bonding, sealing, and potting.

 

According to Master Bond, its clients can expect a tensile strength of 11,000 to 12,00 pounds per square inch and a modulus of between 30,000 and 350,000 pounds per square inch from the product. When optimally cured, the epoxy has a relatively high chemical resistance. For optimal curing, the company recommends an overnight cure at room temperature. After that, three to four hours of exposure to temperatures of 140 to 170 Fahrenheit will complete the curing process.

E70CN is compatible with a wide variety of substrates including ceramics, metals, plastics,and rubbers.

Ford and GM Compete for Truck Lightweighting Advantage

Posted By ASC, Tuesday, October 2, 2018

Ford’s F-series sets new records for fuel efficiency in the market for trucks, and GM was eager to follow suit. But General Motors engineers weren’t sold on the all-aluminum body that kept the F-series bodyweight low. Investigations led GM towards a lower-cost and even lighter weight solution: combining aluminum with high-strength steel.

 

With aluminum costs rising and the threat of import tariffs on vehicles made in Mexico where GM has a plant, both companies face headwinds. But GM is betting that its new, lighter weight Silverado will give it a competitive edge. The company’s lightweighting drive has shaved 450 pounds off the weight of a truck, allowing it to get 23 miles to the gallon.

 

GM’s decision to combine high-strength steel with aluminum has also leading to cost savings which it hopes to use on better entertainment and safety systems. However, despite GM’s efforts to attract consumers with better fuel efficiency and electronics, the F-series Ford truck remains the US national top seller.

 

Who is winning the fuel efficiency battle? So far, average fuel consumption for the two trucks is the same, but the Silverado has a slight edge on the open road where it gets 23 miles to the gallon while Ford gets 21 miles to the gallon. But GM plans to make more extensive use of carbon fiber in future while Ford will continue with its aluminum bodies.

 

As for consumers, they’re happy to get fuel economy from trucks most people see as gas guzzlers, and cost-efficiency is making the truck market attractive to light motor vehicle owners who would previously have balked at the fuel cost implications of driving a truck.

Device Incorporates Adhesives and Clips to Close Wounds Without Sutures or Stitches

Posted By ASC, Monday, October 1, 2018

DermaClip is a new innovation that combines an adhesive wound closure similar to Steri-Strip with a clip that helps to keep the edges of the wound aligned until it can heal.

As a wound closure that does not require needles, stitches, or staples, it is expected to be particularly helpful in situations where skilled personnel are not available. However, the solution may yet be used in settings where such personnel are on hand since it has the advantage of eliminating skin puncturing and could speed would closure time.

Ahesives.org Blog: The Forgotten Transportation Tiers

Posted By ASC, Wednesday, September 26, 2018

Latest Adhesives.org Blog (from Jim Swope, The ChemQuest Group) ...

 

Understandably, the original equipment manufacturer (OEM) tends to be the primary focus when analyzing the automotive market (or the broader transportation markets) due to the sheer size and technical scope of OEM bonding requirements and its relatively large volume of adhesives and sealants usage.  However, by focusing predominately on OEM assembly – at the exclusion of other transportation subsegments such as Tier I, II, and III parts, components, and subcomponents, for example – we can overlook much of the innovation enabled by adhesives and sealants.

 

New, lighter materials that are used to build more energy efficient vehicles have rightfully received copious attention in the transportation value chain. Lightweighting often involves substrates that are conducive to an adhesive solution. Joining mixed materials, thinner gauge substrates, and preventing noise transmission, while also meeting the requirements of automated processes, are all strengths of adhesivesthat OEM’s fully utilize (see Table 1 comparing adhesives bonding to other joining methods). These same OEM bonding requirements apply to Tier manufacturing.

Hybrid Dual-Curing Adhesives Address Light-Curing Limitations

Posted By ASC, Tuesday, September 25, 2018

Adhesives.org Article Highlight...

 

Light-curing adhesives are often preferred in manufacturing industries owing to the productivity benefits they confer as well as the accuracy with which they can be applied.  There are, however, limiting factors. They cannot be used at temperatures higher than 150°Cand they are not resistant to chemical exposure or oil. In addition, shadows cast by the components can limit light exposure, and without this, the adhesive fails to cure. 


Dual curing adhesives provide a solution. For example, when there are shadowed areas, a dual curing adhesive will work with a second curing mechanism such as humidity, heat, or exposure to anaerobic conditions. 


When natural air humidity acts as the second curing mechanism, manufacturers need not use any additional equipment. The process is therefore the same as it would be with a light-curing adhesive. However, these adhesives are not resistant to high temperatures and will only tolerate moderate chemical exposure. UV silicones work in much the same way and can tolerate high temperatures, but they have low bond strength andare only used as sealants. 


Adhesives that couple light-curing with anaerobic curing offer a middle-road solution. They will tolerate temperatures of up to 180°C and will resist harsh chemicals like brake fluid and oil.
Dual-curing adhesives that use light and heat offer the widest diversity of adhesive types ranging from flexible, dynamic-stress-tolerant acrylates to hard, chemical and heat resistant epoxies. Manufacturers first expose the adhesive to light, fixing the components in place so that they will not shift during heat-curing. Then heat is applied using convection or tunnel ovens, induction, or thermodes, curing the adhesive at temperatures from 100 to 120°C.

Adhesives Bond, Connect and Protect Advanced Driver Assistance Systems (ADAS) Components

Posted By ASC, Friday, September 21, 2018

Advanced Driver Assistance Systems (ADAS) are no longer the sole domain of luxury vehicles. They may notify drivers of current conditions, warn drivers of hazards, or even intervene to keep drivers safe. To gather the data they need, the computer-based systems use cameras, radar, LIDAR and other sensors. Many of these will be exposed to harsh operating conditions that are not compatible with delicate electronic circuitry. Moisture, impacts from road debris, or exposure to chemicals and oil are among the conditions the devices must withstand.

 

Henkel says that it offers material solutions that will protect ADAS sensors. The company recommends:

 

  • LOCTITE EA 5470 as a liquid foam gasket for sealing radar enclosures
  • LOCTITE 3217 for use in the precision-bonding camera lenses
  • Conductive adhesives that can be used as connecting solutions
  • Coatings, sealants and potting agents that protect the electronics

 

Henkel says that it expects to see further growth in the market for ADAS component adhesives and sealants as ADAS becomes the norm in a growing number of mid to upper-range vehicles.
