Field Adhesion Tests for Construction Sealants

Posted By ASC, 18 hours ago

Application conditions and methods will determine whether or not construction sealants perform to specification. Rework is costly, so experts recommend on-site tests to ensure that there are no potentially costly errors. In field adhesion tests, the join sealant is applied on site and then tested by cutting an area of the sealant to see how well it is adhering to the substrate.

A failed test could indicate a range of potential problems to eliminate. For example, the sealant or primer could be contaminated, the substrate may not have been cleaned properly, the wrong primer may have been chosen or the primer may have been applied incorrectly, the substrate could have too much movement, coatings could be incompatible, and so on. There are two possible types of failure to look for: cohesive failure, and adhesive failure. 

When conducting a field adhesion test, a log recording the date and location of the adhesion test, the age and identity of the sealant, the width and depth of the sealant applied, and the test results should be kept.

From HVAC to Outer Space, Aluminum Foil Adhesive Tape Offers Solutions to Critical Issues

Posted By ASC, Tuesday, December 11, 2018

You’ll find aluminum foil adhesive tape in everything from furnaces to space gadgets. The tape’s versatility is attributable to its unique properties beginning with the most basic reasons to choose a foil tape: complete fire resistance and the ability to reflect heat and light.

Combine that with UV resistance and an adhesive that can tolerate a huge range of temperatures (-65F to 300F) and still hang on tight yet peel off cleanly when deliberately removed, and it’s even clearer why its aluminum foil tape is a standby in almost any toolbox.

Finally, there’s the advantage of conformability that comes with using aluminum foil adhesive tape. Even if the surface is curved or corrugated, the tape follows the contour. The tape is widely used in HVAC repairs and maintenance, in manufacturing fridges and freezers, and as a means of protecting delicate components from extreme heat.

Increased Use of Mixed Materials and Structural Adhesives a Continuing Trend in Auto Manufacturing

Posted By ASC, Friday, December 7, 2018
Emissions targets are still driving automobile lightweighting initiatives, but they’re not the only reason why auto manufacturers are following the trend towards mixed materials and structural adhesives in auto design and manufacture. It also helps engines to deliver better performance and gives motorists a better ride.

Choosing the best material for every component may make sense, but in the past, the difficulty of bonding components made from different materials together limited designers’ scope. But with structural adhesives overcoming fastening and substrate interface problems, the use of mixed materials is gaining momentum.

The Center for Automotive Research predicts that a body in white, which currently has an average of 55 percent mild steel, will only be 5 percent mild steel by 2040. The organization tips aluminum and composites to take steel’s place. Already, adhesives are making this possible, and the materials advances of the future will go hand-in-hand with innovation in adhesives.

How Ingevity's Resin Helps Improve Road Markings to Save Lives

Posted By ASC, Tuesday, December 4, 2018
A highway death in the U.S. occurs every 21 minutes as a result of a lane departure. This equates to over 25,000 fatalities annually and represents almost 60 percent of the fatalities on America’s highways. The U.S. spends approximately $2 billion each year on thermoplastic pavement marking materials, and many transportation agencies and research institutions continue to experiment with ways to enhance pavement markings as a method to reduce road fatalities.

Ingevity, a specialty chemicals company headquartered in North Charleston, S.C., manufactures tall oil rosin resin that helps lane markings retain retro-reflectivity better after exposure to everyday wear and tear, and harsh weather conditions.

According to the company, the unique properties of WestRez® provide superior adhesion of the glass beads in the thermoplastic marking materials that enhances visibility and extends the life of the lane striping. This means that transportation agencies can save money, and ultimately reduce accidents and deaths on our roadways related to lane awareness.

3M's Adhesive Cartridges Address Common Problems

Posted By ASC, Monday, December 3, 2018

3M’s Scotch-Weld cartridges have recently undergone changes that target waste reduction, improve dispensing and mixing, and reduce the chance of leaks. The improved cartridge design features a cap that’s designed to prevent the accidental bonding of cap to cartridge while still preventing the cartridge’s contents from drying out. 

Meanwhile, the dispensing outlet has been improved for enhanced adhesive flow and precise mixing during application. A sealing flange which locks the pistons makes the cartridges acceptable as air cargo.The piston-sealing system has been further improved to distribute pressure evenly during application, reducing leakage and waste by replacing the previous O-ring with a double-lip seal.

The cartridges are produced in 48.5ml and 50ml sizes for the 1:1 and 2:1 Scotch-Weld adhesive systems. Despite the investment in the development of the improved packaging, the cost of Scotch-Weld adhesives will remain unchanged. While the manual applicator will work well with the 48.5ml cartridge, the 50ml 2:1 cartridge is for use with a pneumatic applicator.

Henkel Offers Sealant for Extreme Temperatures and Pressures

Posted By ASC, Thursday, November 29, 2018
Updated: Wednesday, November 28, 2018

Industrial customers from power plants to steel mills and refineries require extreme performance from their sealant solutions that can operate under demanding conditions. Industry manufacturer Henkel offers its Loctite NS 5540 and NS 5550 for extreme temperatures and pressures. Despite forming a good seal, the company reports that its products still allow for easy disassembly of components during repairs or maintenance. 

Both sealants are chemical resistant, tolerating exposure to oils, acids, hydrocarbons,and steam while not being affected by thermal cycling. NS 5540 is a liquid formulation that tolerates temperatures of up to 700C (1,300F) pressures up to 200 bar (2900 psi) while NS 5550 withstands 340 bar (5,000psi) and temperatures of 815C (1,500F) and is formulated as a paste.

Typical industrial applications include turbines and pump casings, boilers, stacks, heat exchangers, exhaust systems, steam traps, and ductwork. 

The company says that the two products are easy to apply – with a brush for the liquid and a spatula for the paste – and will cure with exposure to heat.

Industry Innovations Focus on Important World Trends

Posted By ASC, Wednesday, November 28, 2018
Energy efficiency, recyclability, and adhesive strategies that will allow us to extend products’ lifespan or repair them are among the strategic goals. Manufacturers are using adhesives to reduce their use of plastic in packaging,and the emphasis on positive environmental impacts seems very likely to continue making news. 

Dow, for instance, provides an example of improved recyclability thanks to its PE stand up pouch These traditionally consisted of aluminum and plastic layers – but they couldn’t easily be separated to allow for recycling. Dow developed a pouch in which two layers of recyclable plastic were bonded using a polyurethane adhesive. Now, the entire package can be recycled.

Electronics companies are among the manufacturing concerns interested in peelable liquid adhesives. They bond components securely to their substrates but allow them to be peeled away and replaced if repairs become necessary.

Growing interest in adhesives that are based on or mimic natural proteins has led to a great deal of research and development that targets the replacement of oil-derived adhesive ingredients. Biomimicry continues to draw research interest, with the most recent newsmaker being work on adhesives that will form bonds in wet environments.

Precision engineering industries and the makers of medical implants and appliances continue to express their interest in ultraviolet and electron beam technologies. Currently, UV resins are most often used as laminating adhesives, but their market share grows comparatively slowly compared to the pressure sensitive adhesives market. Once again, the new adhesives target sustainability with reduced use of PVC and solvents.

Middle-School Science Project Results in a Non-Permanent, Kid-Friendly, Antimicrobial Adhesive for Legos

Posted By ASC, Wednesday, November 14, 2018
Updated: Tuesday, November 13, 2018

Tripp Phillips may be just 11 years old, but his adhesive is likely to be the next big thing for Lego enthusiasts. Tripp is an avid Lego builder, and enjoys making complex creations with moving parts – but the Lego bricks didn’t always stay clipped together for as long as he would have liked. At times, he would use adhesives to stick the bricks together, but then it would be the end of the road for the bricks.

So, Tripp knew exactly what he wanted when he approached his father, an expert in adhesive chemistry, for help with his science project. With some extra input from his dad’s colleagues, they developed a non-toxic glue that will hold the bricks together,but that can be dissolved in warm water. The new adhesive, named Le-Glue, is fully compliant with all the relevant regulations and even contains antimicrobial agents that will prevent mold growth.
