Sika Corp Releases New Mirror Grip Adhesive for Vertical Mirror Installation

Posted By ASC, Wednesday, June 28, 2017

Sika Corporation has added a new product to its Flat Glass product range. The adhesive has been designed specifically for bonding mirrors to vertical surfaces and is effective across a wide range of interior substrates. The company says that its new product allows for instant grip and reduces the amount of material needed to fix mirrors to surfaces. Vertical beads can be spaced eight inches apart, whereas older products required a five-inch spacing between beads.

 

Sikaflex®-124 Mirror Grip will not cause any discoloration or staining of the mirror, is low in solvents and adheres well to Category II safety film. Although the company says that its product grips instantly, it nevertheless recommends using mechanical support during and after installation to ensure absolute safety. However, it notes that Sikaflex®-124 Mirror Grip will eliminate the need to use several products for different types of mirror installations.

Adhesives.org BLOG: What makes Firestop different from other sealants?

BLOG:  What makes Firestop different from other sealants?
 
By Sharron Halpert, Adhesives.org Expert Blogger

 

There is one important element in firestop materials that makes them different from so many other sealants is the way they behave in a fire. Of course the “secret sauce” that goes into the product that makes them more expensive than other sealants also. The key element in many, but not all, firestop products is their capacity to expand when the product is exposed to the heat seen in a fire scenario. The industry lingo is intumescent. When looking at the sealants used in firestop they are either used in joint applications so they need to allow for movement, or they are used in through penetrations in which case many applications will require an intumescent product. Today we will discuss why this more expensive material can not be substituted for the non-intumescent material.


First of all, this intumescent material is needed when dealing with combustible through penetration such as insulation around pipes or ducts. As the fire causes the insulation to melt or soften, the expanding intumescent firestop will close the gap that is created. It’s even more obvious that intumescent material would be needed around plastic pipes. Plastic pipes will melt at temperatures around 300F-500F degrees, depending on their chemical composition. For many pipes under 2” diameter an installer can use an intumescent sealant. “Many” is a tricky word. It alludes to the potential for exceptions, and in this case the exception is FRPP, plastic fire sprinkler pipes. Most manufacturers will not be able to firestop 2” diameter FRPP with just sealant.


Some firestop materials are not even compatible with FRPP because over time the chemical incompatibility will etch holes in the plastic pipe. It is recommended that installers check the...

The Many Benefits to Choosing Structural Adhesives for Your Next Application (Part 2 of 2)

Posted By ASC, Friday, June 23, 2017

Structural Adhesives Save Manufacturers Time and Money

 

When structural adhesives are used to bond components together, manufacturers save a great deal of production line time and realize cost savings. For example, welding takes a considerable amount of time and expertise and leads to a need for additional steps to obtain a neat finish. If they choose to use nuts, bolts, and rivets, there will be several attachment points per component, and each of these will add to the amount of labor needed to create a finished product.

 

In most cases, adhesive application is a single-step process. Whereas the two-part epoxies of the past required a mixing process, many modern epoxies are no mix products that are applied using advances such as static mixing wands that precisely measure and mix the components during use. Adhesive technology advances have also reduced cure time, and even longer-curing adhesives often produce bonds that will allow for component handling within minutes or even seconds. Instantly curing UV adhesives and cyanoacrylates were previously not suitable as structural adhesives, but they too have advanced. These adhesives are now suitable for lower stress structural bonds.

 

By eliminating the need for an extensive inventory of fasteners for different components, reducing the number of steps in the production process, and reducing the time needed for each process, structural adhesives enable manufacturers to reduce costs and save time.

The Many Benefits of Choosing Structural Adhesives for Your Next Application (Part 1 of 2)

Posted By ASC, Wednesday, June 21, 2017

Manufacturers and engineers are increasingly choosing structural adhesives over other methods of fastening such as welding or rivets. Uptake of these high-tech materials has been widespread in the automotive and aerospace industries, and appliance manufacturers are beginning to adopt them more widely.


Structural adhesives are particularly useful when bonding dissimilar metals, when thermal cycling forms part of the product environment, and when corrosion risk must be avoided. In these instances, adhesives reduce the effect of differing thermal expansion rates and provide a barrier between metals that would corrode if they were in direct contact with one another. In addition, while water or chemicals can penetrate into areas secured by mechanical fasteners, adhesives seal the bond.


The benefits of lightweighting provide a further incentive for manufacturers to choose adhesives over traditional fasteners. Airlines realize substantial cost reductions and reduce emissions when weight is reduced, and car and boat manufacturers have followed suit for the same reasons. But it is not only end users who enjoy the benefits of reduced costs. Although specialized structural adhesives themselves may seem costly, they offer manufacturers a single solution that can be used in many different ways, reducing or eliminating the need for specialized fasteners and saving time in production lines.


The final appearance of the bonded components is also an issue. Welded seams require finishing, and traditional rivets, nuts and bolts spoil the clean lines most product designers and consumers prefer to see. Finally, structural adhesives improve product performance and durability since it is not necessary to drill holes through components, creating weakened areas that carry concentrated loads and are subject to corrosion.

Coatings and Sealants Manufacturers Will Help to Prepare for the Rise of Autonomous Vehicles

Posted By ASC, Tuesday, June 13, 2017

Automakers are racing to create a future in which driverless cars will rule the roads, but despite progress which indicates the inevitability of this development, city planners are not incorporating it into their infrastructure plans. The pressing question is just who should be responsible for creating smart infrastructure that includes standing structures that will be easily identifiable to an autonomous car’s sensors.

 

Federal, state and local governments are already struggling to maintain existing infrastructure with highways badly in need of repair. This indicates shortfalls in funding – but further funding will be needed to convert infrastructure into smart infrastructure.

 

Just as the rise of the automobile led to the construction of roads and highways that could accommodate the new mode of transport, so modern infrastructure must change with the times. Cooperation and standardization will be the order of the day, and both government and private enterprise will need to be innovative.

 

Coatings manufacturers will have an important role to play thanks to their long-standing relationships with OEMs. For example, coatings and paints will need to have infrared light reflecting properties to optimize detection of objects by electronic sensors. Current coatings in darker shades still absorb too much infrared light, making them more difficult to detect. Coatings and sealants will also protect the sensors and their related electronics. For example, they will be needed for sealing sensor covers and lenses to protect them from dirt and moisture.

 

Our cars are changing, and materials and infrastructure must change with them,creating new opportunities for innovative sealants and coatings that will facilitate a smooth transition to driverless transportation.
