Adhesives for Ventilators – Special Properties for Life Saving Use

Posted By ASC, 18 hours ago

Finding an explanation for why the world is fighting a deadly virus without enough ventilators to assist it in the struggle against a respiratory virus is not easy, but understanding the complex requirements of only one section of their assembly might make it at least a little clearer. Adhesives, for instance, need to have high and numerous credentials before they can be used in the assembly of medical equipment, especially so when that equipment is scheduled to help patients with respiratory problems, like those seriously affected by Covid-19.


According to medical adhesive manufacturer MasterBond, some of the most vital properties required include good strength, high speed processing and often a high degree of flexibility. But to be suitable, adhesives also have to get through stringent tests for biocompatibility and cytotoxicity, and in many instances are restricted from containing certain materials. They must also be suitable for use bonding the parts of equipment that is resistant to a wide range of temperatures, sterilants and chemicals and at the same time be able to bond with a wide array of substrates from acrylics, polycarbonates and polyesters, through metals, ceramics, plastics and some electronic components.

 

Assembly of parts like filters, valves, cartridges, tubes, gaskets, sensors and face shields, all of which can become parts of Respiratory Device Assembly require certain adhesives.

 

These Medical Grade Adhesives Include:

 

  • UV curing systems that can be biocompatible per USP Class VI testing with medium viscosity, abrasion resistance, non-yellowing, thermal and electrical insulating qualities, serviceable from -80°F to +250°F, and resistant to exposure to radiation, Et0 and chemical sterilants.
  • Low viscosity epoxy adhesives, sealants, coatings and casting compounds that are USP Class VI approved and resist vibration, impact, shock, thermal cycling. They must be suited for bonding dissimilar substrates, serviceable from -80°F to +250°F, exposure resistant to EtO, radiation and chemical sterilants, and have excellent toughness.
  • Specially formulated one component systems must cure at room temperature, have a viscosity of less than 250 cps and be serviceable from -60°F to +200°F. Other requirements are that they must be suitable for both bonding and priming polyolefinic surfaces to promote adhesion of polyolefinic substrates to other surfaces such as metals and ceramics, and must pass ISO 10993-5 for medical devices.
  • Dual cure systems with UV and heat curing mechanisms which cure at 80°C in shadowed out areas must be Nano filled, and have high dimensional stability and abrasion resistance. They should also able to bond well to metals, glass, ceramics and most plastics, and be serviceable from -60°F to +350°F.
  • Single component silicone with a paste viscosity for bonding, sealing and coating medical devices should be non-corrosive and neutral cure. The compound must comply with USP Class VI and ISO 10993-5 specifications and resist many kinds of sterilization including gamma and other types of radiation, as well as EtO and some types of liquid sterilants.

Covid-19: Hot Melt Adhesive Helps Sportswear Company Produce 100,000 Masks Weekly

Posted By ASC, Monday, April 6, 2020
Under Armour athletic wear manufacturers have switched their focus and manufacturing machinery from making active wear to meeting medical gear needs in response to the Coronavirus pandemic. In light of the current global shortage of protective gear for medical workers the company has produced its own design for disposable protective masks, which it envisages should allow for production at a rate of 100,000 masks a week.

The company reports that to ensure speedy production, the masks are created without any sewing. Instead, they are made from a single piece of fabric similar to that used for surgical masks, which is cut in bundles of about 100 on the company’s knife cutter. They are then carefully folded by a group of volunteers to cover the entire face, and the folds are held together by thermoplastic hot melt adhesive (HMA), also known as hot glue, which creates a very secure bond critical to the design and function of the masks.

Initially the protective masks will be distributed at cost to the University of Maryland, John Hopkins Medicine, LifeBridge Health and Medstar, all of which are situated in Maryland, a US state currently fighting against fast escalating numbers of confirmed Coronavirus cases and deaths.

Although the disposable masks have not been certified by a medical organization, the company reports that they can act as effective barriers against the virus for those medical workers not working directly with Covid-19 patients; or be used as an extra shield to prolong the life of the respiratory N95 mask used by those in ICUs or Covid-19 patient wards.

In addition to the masks, Under Armour is also using hot melt adhesive to produce plastic face shields (for use with the masks). It’s also investigating using its 3D printers to generate N95 and N80 masks.

Stamping Out Adhesive Fungus to Save both Bond and Parts

Posted By ASC, Thursday, April 2, 2020
From irritating and annoying to downright destructive, fungal growth on adhesives can lead to problems when it comes to electronics and small electrical equipment parts. When the adhesive is not fungus resistant, fungus can affect both the adhesive bond and its surroundings, by breaking the resin in epoxy-based adhesives down into particles which are small enough to allow it access to the carbon in the resin, which it regards as a nutritional source.

Fungus can lead to a series of bad outcomes, according to MasterBond. The molecular degradation which results from the particle breakdown can weaken the core performance of epoxy (and therefore the bond), and so reduce the adhesive’s ability to protect against moisture and chemicals.

As the fungus grows and spreads, it may also build electrical bridges over insulation materials, leading to electrical failures, or fuse together small mechanical parts and restrict their movement. Fungus also tends to attract or add moisture to its living environment which can also negatively impact on the bond.

These problems have driven MasterBond to put six of their fungus resistant adhesives through tests drawn up by the US Defence Department to determine microbial growth in adhesives. The company reports that it was rewarded with winning zeroes on all of them. Compared against a control specimen which registered a high 4 for heavy growth, MasterBond’s MasterSil 151AO; EP36AN; EP39MAOHT; EP3RR-80; EP30LTE-LO; and EP37-3FLFAO; which vary in their applications and qualities, all registered as showing no microbial growth whatsoever.

Adhesive Backing Helps Cut Security Wires, Saves Money

Posted By ASC, Wednesday, April 1, 2020
With the importance of home security constantly on the rise, and more and more home-owners attempting to take on security installations themselves, adhesives are stepping into the role of DIY security application superheroes. They are doing this by saving the less handy from hours of hard wiring, as well as cutting costs and adding extra safety to the home by making it near impossible for intruders to disable it by removing the option of cutting the wires.

The adhesive backings fall right in line with the online SimpliSafe concept, an eight-component wireless security system. These include components which are attached to the wall as well as the sensor/magnet combinations which trigger the alert when a door or window is opened. All these are attached by simply removing the adhesive backing’s cover tape, and activated by removing the battery activation strip attached to each of them with easily removable adhesive tape.

The system is powered by a five-year battery and controlled by a base station which holds the fort, keeps the householder in touch with the on line company, a keypad and remote control.

Can Sealants Be Fun? DIY Grouting Options Say Yes.

Posted By ASC, Tuesday, March 31, 2020

It’s cheap, shiny, and full of bling and glitter. That’s hardly the first description that comes to mind when thinking about grout, which is more usually viewed as an uninspiring material used simply to fill the gaps between newly applied tiles, or update the look of older tiling. But in many homes, grout is now becoming a décor trend with the introduction of a glitter grout.


The new easily tooled silver or gold clear glitter adhesive and sealant is fast becoming a favourite for those thinking of giving dull places in the home a tweak. It can shine a path not only as grout between tiles, but can also be used on the tiles themselves, and on concrete, bricks, metal and stone, for decorative as well as practical purposes. Applied with a pen-like dispenser, it allows for various ways to add a glittery shine to areas in the home which may be looking a little drab. These include kitchens and bathrooms, which some find to be rather gloomy and clinical and may feel a little twinkling may change the ambience.

New Crack Sealing Machine for Roads, Airfields, Bridges and Parking Lots

Posted By ASC, Thursday, March 26, 2020
Industry solution provider TICAB has launched a new crack-sealing machine, the BPM-500, for filling and sealing the cracks that develop in highway surfaces, parking lots, on bridges, and on the tarmacs of airfields.

Supported by a frame, the sealing machine is designed to be installed on a truck or trailer. Powered by a diesel engine, its 500 litre (130gal) capacity tank is filled through the machine’s upper hatch using an electrically heated hose.

Once loaded into the tank, the bitumen-elastomeric sealing compounds are mixed with horizontal paddles and heated by thermal oil to a maximum temperature of 200°C (390°F) before being used to fill and seal the cracks using a pump with hydraulic drive. For optimal results, an optional hot air lance is available to clean and heat the cracks before they are filled.

Die-Cut High Adhesive Tapes: Customizing to the Job at Hand

Posted By ASC, Wednesday, March 25, 2020

A solutions provider in the adhesive tape space, Budnick Converting, has added another advantage to the list of benefits already associated with using high bond acrylic foam tapes, which include temperature and shock resistance, design flexibility, absence of long cure times, ability to bond dissimilar materials, and light weighting. The company reports that these versatile high bond acrylic adhesives can also be converted to match the user’s exact application requirements in terms of form, shape and size using die-cutting, so increasing the efficiency of production.

 

According to the company, the die-cut option saves time spent on trimming parts by hand (and running the risk of injury while doing so), uses less material because of the company’s ability to reduce scrap by spacing parts carefully, and leads to a consistency seldom achieved manually. The company is also able to present the customized die, cavity, butt, or cavity cut tapes individually, in sheet form, or on rolls.

Take the Squeak out of Stairs with Adhesives and Foam

Posted By ASC, Thursday, March 19, 2020

While old squeaky stairs can range in emotional impact from being irritating to almost causing a panic attack, there’s no need to sell-up and move out because of them. For those with a DIY inclination the answer to the problem lies in construction adhesive and closed-cell foam, plus a bit of work, and the stairs will become quiet once again.


Tips from those in the know suggest that this approach can be used on both new stairs as a precaution against their becoming creaky in the future, and on old stairs which already make a noise.
For these veteran staircases, the best approach is to either shim the treads and risers from below, or drive the existing shims deeper, and glue them in place with construction adhesive. The next step is to fill in the seams between the treads and risers with the same adhesive, and tool it into the joints before using screws to bond the treads and risers more securely to the stringers that link the flight of stairs.


Where does the closed cell foam come in? It’s the final step in the stair-quietening process. The foam is sprayed over the entire underneath surface of the stairway to a thickness of about one inch. This deadens any sound as well as locking the structure together.
