Sealant to Save Washington, D.C. Metro’s Red Line Subway

Posted By ASC, Tuesday, December 26, 2017

For years now, Washington, D.C. Metro’s Red Line has been battling a persistent threat from nature. The extra-deep underground segment has long been serving as a drain for underground water that once seeped into a nearby creek, and the persistent leaking that resulted has raised fears for the line’s safety.

Now, technicians believe that they have found a workable solution, and the Red Line Water Leak Pilot Project is underway. It aims to encase the tunnel with a special sealant that will form a leak-proof membrane. The ceiling of the tunnel will be drilled in hundreds of places, and then the sealant will be injected. Paul J. Wiedefeld, Metro Manager, says that the new strategy is effective but needs to undergo a testing period. In time, he hopes that the sealant process can be used along the length of the Red Line where leaks have caused track fires in the past.

ASTM International Standard Measures Residual Stress in Various Building Sealants

Posted By ASC, Thursday, December 21, 2017
Updated: Wednesday, December 20, 2017

A new ASTM International standard will help manufacturers and regulators better understand how building sealants change once they have been compressed or stretched. The standard (C1815) was developed by ASTM International’s committee on building seals and sealants (C24).

“Think about the last time you rolled out pizza dough,” says ASTM International member Christopher White, a research chemist at the U.S. National Institute of Standards and Technology. “You would stretch the dough and it would change shape some, but then spring back as well. If you held it stretched out, it would spring back a smaller amount. This is what some sealants do when installed in a building.

 

White says this standard helps quantify that behavior.

 

"This is important, as the sealant will fail when the internal stress is greater than the tear strength,” notes White. “This standard allows the community to start to understand and quantify the time-dependent response of the sealant.”

 

The standard will be used by manufacturers to measure the residual stress in various sealant formulations. In addition, regulators will use the standard to modify existing sealant standards to incorporate sealant compression behavior.

To purchase standards, contact ASTM International customer relations at (877) 909-ASTM or at sales@astm.org. For more information on building sealants and other relevant standards, download the ASTM International construction standards overview document.

RODA Introduces New Range Of Flexible Tubes For Adhesive Packaging

Posted By ASC, Monday, December 18, 2017

RODA Packaging is best known for its rigid plastic packaging and closures, but the company has extended its offering to include a range of extruded flexible tubes. Since its packaging was primarily used for caulk and sealant fiber, the production of flexible tubes for adhesive and grease packaging was the next step for the company in the diversification of its product range. The company says that the new addition to its offering comes as a result of market demand and a limited number of suppliers within the niche. Its capabilities embrace a production capacity of 22 million units per annum combined with attractive options for decoration and presentation.

 

RODA Packaging is able to provide 10-colour, high definition printing including pearlescent and metallic or foil finishes. In addition, it can assist with hot stamping, offset printing, and screen printing. Monolayer, coextrusion and laminate variants of the flexible tubes are available. They are resistant to moisture and are compliant with the relevant ISO standards.

When Adhesives Don’t Replace Rivets, They Strengthen Them

Posted By ASC, Friday, December 15, 2017

Rivets are being replaced by adhesives – but there are still areas where they are often used. Heavy-duty truck bodies are among these, but while the rivets bond the panels effectively on the factory-floor, the vibration of regular driving causes fatigue, while contact between rivets and aluminum panels causes corrosion. The latter problem is usually overcome by using a coating – but during repairs, the coating may be breached resulting in corrosion.

3M recently released information on how to prevent these problems through rivet bonding.It recommends 3M PN8115 Panel Bonding Adhesive for use in conjunction with rivets. When using the product with rivets, stronger bonds are formed, and the material acts as an isolator between dissimilar substrates that would otherwise corrode. At the same time, it prevents leaks and reduces vibration that would otherwise place strain on rivets. When using the product solely as an isolator between dissimilar substrates, a simplified process is followed.

Given that product selection depends on a variety of factors, choosing the right one can be difficult. To help repairers make the right material choices for the task at hand, 3M provides detailed information about its products and how to use them on its website.

B+BTech's New Hybrid Injection Adhesive Boasts Extreme Load-Bearing Capacity

Posted By ASC, Tuesday, December 12, 2017

B+BTec has announced the culmination of its latest product development initiative: a high-performance anchoring system that depends on its newly-developed injection adhesive. The product is used in conjunction with threaded rods and rebar and is used to reinforce concrete structures. The formulation has been assessed with an ETA Option and was found to be suitable as an all-terrain anchoring solution.

 

Apart from its high load bearing capacity, it cures in just 30 minutes at room temperature, can be used in flooded holes and tolerates extremely high temperatures. Its ability to maintain its integrity during short exposure to temperatures of 160˚C and longer-term exposure to a temperature of 100˚C makes it suitable for use in the construction of areas surrounding blast furnaces.

 

Finally, the new system, when used with threaded rods M8 – M30 and rebar diameter of 8mm – 32mm, has achieved C1 classification.

Adhesives Help Auto Manufacturers Eliminate Bond Line Read Through (BLRT)

Posted By ASC, Thursday, November 30, 2017

As auto manufacturers continue to move towards thinner composites in order to meet lightweighting targets, bond-line read-through (BLRT) has become an increasingly important issue. Ideally, bond lines should be invisible to the naked eye, and when they can be seen, consumers may reject the finished product. As a result, quality controllers may reject components that exhibit BLRT, resulting in rework and higher costs.

 

The use of dissimilar substrates that expand at different rates when heated or contract to a greater or lesser degree when cooled contributes to BLRT. This can cause deformation of the adhesive, particularly when large volumes are used. Differences in the bond gap have a similar effect.

To solve the problem, experts recommend design, process, and adhesive choices that will limit BLRT. Thus, the properties of the adhesive, the design of parts, and production processes will all have a role to play in mitigating BLRT.

 

The issue has been thoroughly researched by Ashland, and the result was a selection of epoxy and polyurethane structural adhesives, and hybrids using both adhesive technologies, that would also cure quickly and be heat resistant. These adhesives had to pass ecoat – a 40-minute exposure to a temperature of204°Cfollowed by a lap shear strength of 0.3MPa at the same temperature.

 

Once the testing had been concluded, Ashland’s research team selected four two-part polyurethane/epoxy adhesives and one epoxy which showed promise as a means of reducing BLRT while still passing ecoat. In addition, the chosen adhesives had to meet rapid curing targets of eight to sixty minutes. Of the selected adhesives, the epoxy demonstrated the highest tensile strength and modulus.

 

The next step was to measure BLRT with the help of a Zeiss surface analyzer. Adhesive bead width, the relationship between bond gap and curvature, and cure time were among the variables taken into account in Ashland’s study. The researchers were able to make the following conclusions:

 

  • Shorter cure times resulted in lower curvature
  • As bond gaps increased, so did curvature
  • Lower curvature was associated with lower modulus
  • Adhesive bead width did not affect curvature

 

They therefore concluded that high-elongation, low-modulus adhesives allow engineers to...
