Thermal Imaging Helps Chemicals Company to Monitor Package Sealing Quality

Posted By ASC, Thursday, February 23, 2017

Recochem Inc., a Canadian manufacturer of chemical products and fluids, needs to ensure that its products are effectively sealed in the packaging process to safeguard product quality and safety. It distributes windshield fluid in jugs packaged within cartons with an overwrap. The cartons are sealed with a hot-melt adhesive, and Recochem needs to check that the adhesive has been correctly applied. To do this, the company is using thermal imaging using an FLIR AX8 thermal imaging camera.


The camera can “see” through the carton, checking adhesive spot sizes and temperatures. The thermal images show the higher temperature areas where the adhesive has been applied. If there is a problem with the glue gun, the hotter spots form a different pattern, alerting a technician who monitors the images. Previously, quality controllers would choose and destroy a random box every 10 to 15 minutes so that it could be inspected, but now, both the time needed for this and the waste of cartons has been eliminated from the packaging line. The company says that the resulting time and money savings are significant.

New Low Halogen Adhesives from Techsil Looking to Provide Greater Precision for Electronics Manufacturers

Posted By ASC, Tuesday, February 21, 2017

Techsil has announced the release of two new adhesives specifically formulated to increase adhesive dispensing precision in the manufacture of electronic components. The two low halogen adhesives, Vitralit UD 8050 and Structalit 8838, encapsulate components on PCBs and are said to provide better flow control and dispensing precision owing to their viscosity.

 

The two products are “glob top” adhesives used to seal and encapsulate components. They prevent moisture, dust, dirt and solvents from entering the components and protect them from mechanical damage.

 

Vitralit UD 8050 is a fast-curing single component acrylic adhesive. It will be well-suited to the manufacture of consumer electronics, and easy dispensing and rapid curing under UV light will help manufacturers to keep production lines efficient according to the company. A formulation that contains a fluorescent marker will help quality controllers to check components with ease.

 

Structalit 8838 is a single component epoxy offering rapid thermal curing, a low glass transition temperature, and excellent flexibility. It performed well in temperature and moisture tests, protecting the components without impairing their functioning.

Adhesives.org BLOG: Insights to the National Institute of Building Sciences - 2017 Building Innovation Conference

BLOG:  Insights to the National Institute of Building Sciences - 2017 Building Innovation Conference

 

By Paul Bertram, Adhesives.org Expert Blogger

 

As 2017 year began, the National Institute of Building Science held its annual Building Innovation conference in Washington DC in January. Resilience was the one overarching theme that resonated in many of the sessions. Resilience, for the purpose, of this discussion, was presented as: How fast a building can rebound from extreme weather conditions.

Establishing a definition for Resilience falls into the same problematic categories of “Sustainability” and “Durability”. These terms seem to be interrelated and causing confusion in the industry.

In sessions related to building codes, ICC representatives expressed that resilience is already in the codes. They cited examples that included wind & snow loads, tornadic impacts, fire, seismic, and flooding. During this session, Resilience was defined as: the ability to prepare and plan for absorbing and recovery; or more successfully adapt to actual or potential adverse events. Key to this presentation was the reminder that building codes are the minimum level of compliance requirements.

In many of the presentations building code adoption was cited as an impediment for delivering High Performance resilient buildings because of the long code development improvement cycles and even longer adoption timelines. In relationship to increasing extreme weather conditions, this leaves buildings more vulnerable to expensive damage and insurance payout, let alone the social impacts.

The ICC compliance process is intended to construct safe, sustainable, affordable and resilient structures. Recently, the ICC Board directed staff to engage the stakeholders by announcing a "Call for Feedback" on any and all aspects of the ICC code development process. The next step in the process is the deadline for feedback, which...

Dow Corning Targets Growing Wearable Medical Devices Market with Silicone Adhesive

Posted By ASC, Wednesday, February 15, 2017

The growing market for wearable medical devices is expected to grow to $27.8 billion by 2022. Dow Corning says that adhesive technologies will drive growth in the wearables market. Specialized adhesives will be developed based on factors such as how long devices are to be worn, their size, and their weight. Patient comfort will be an important factor. If patients find wearable devices uncomfortable, compliance will be lower, even when devices monitor important physical processes and dispense treatments.

 

Other factors contributing to the medical wearable devices growth trend include an aging global population, the prevalence of chronic conditions, a growing patient interest in self-management of health and fitness, and the need to reduce costs by extending out-patient care. The adhesives used for skin-adhered devices must provide comfort during both the period when they are worn and when the devices are removed. Silicone-based pressure-sensitive and soft-skin adhesives fulfill the need for biocompatibility, repel water, and can be designed for different levels of adhesion strength and tack. Dow Corning’s MG 7-1010 Soft Skin Adhesive with its high adhesion level is an example of the medical adhesives already developed by the company.

Techsil Releases a New Solvent-Free UV-Adhesive for Bonding of Elastomeric Materials

Posted By ASC, Tuesday, February 14, 2017

Rubbers and elastomers have differing polarity, surface properties, and polymer structures. In the past, this has made bonding with adhesives difficult. Until now, cyanoacrylates have offered the best solution, but they have little resistance to impact and easily become brittle according to UK-based adhesives technology company Techsil. They have announced a new solvent-free UV-adhesive to address the issue.

 

According to the company, the product, Vitralit VBB-2N LV has low viscosity and high bond strength. It has been developed specifically for bonding elastomeric materials and cures quickly under UV or visible light making it well-suited to high-volume and automated production line manufacturing.

 

The new adhesive is suitable for bonding large areas and is effective when gap size is very small. After curing, the adhesive remains flexible with good environmental stability. Techsil says that its new product is suitable for use on most elastomers. Vitralit VBB-2N LV will be well-suited to medical applications, meeting the USP Class IV requirements. It can also withstand autoclaving, gamma irradiation and EtOsterilization processes.

Researchers Find Similarities Between Barnacle Adhesive Proteins and Insect Silks

Posted By ASC, Monday, February 13, 2017

A study by the Naval Research Laboratory (NRL) published in Scientific Reports concludes that the proteins used in tough natural adhesives that help barnacles cling to rocks are similar to those found in insect silks. It has long been known that barnacles are more closely related to insects than mussels and tubeworms, and the similarity in their adhesive chemistry may point to a closer relationship than has previously been considered.

 

The research heralds the discovery of a previously unknown class of specialized proteins, and the mesh-like adhesive structures that barnacles produce is more complex than expected, consisting of over 50 proteins and enzymes. The proteins are made up of flexible amino acids arranged in repetitive sequences, and it is these sequences of amino acids that indicate the similarity of barnacle adhesive to insect or spider silk.

 

The NRL’s discovery not only sheds light on one of nature’s toughest adhesives but will provide valuable information to shipbuilders seeking to solve the problem of barnacle accumulation on ships’ hulls.
