Adhesives Used to Improve Optical Lenses

Posted By ASC, Thursday, December 10, 2015

Micro-optics, a development that was first introduced in mobile phone cameras in 2007, are now used for a variety of applications. These include LED flash modules, infrared sensors, ambient light and proximity sensors as well as cameras.


Optical wafers consisting of multiple small lenses are used to manufacture devices using micro-optic technology. Crystal clear adhesives are used in the assembly of these optical wafers, and together with the lenses, adhesives are helping to improve quality while reducing costs. The adhesives allow manufacturers to attach a large number of optical and optoelectronic components to each glass wafer.


This technology allows for greater image quality through reduced pixel sizes, and the UV-curing adhesives offer excellent optical clarity while withstanding temperatures of up to 260°C and tolerating humid environments. Today, high-power Fresnel lenses are manufactured using optical adhesives.

Adhesives Deliver Innovative Solutions to Nike, Coach, Athletica

Posted By ASC, Tuesday, December 8, 2015

Brands like Nike, Coach and Athletica are facing labor shortages, most recently in China, previously a go-to destination for outsourced sewing and stitching work. But adhesives technology is stepping into the breach. Bemis Associates offers sew-free alternatives in the form of adhesives, allowing designers to create new products that don’t call for sewing or stitching.

 

Adhesives allow for bonding with heat and pressure, enabling designers to ‘ditch the stitch’ to deliver more durable products than traditional, stitched designs. Additionally, lighter weight products can be produced utilizing innovative adhesive technologies.

 

Bemis traditionally specialized in adhesives used for labeling and in footwear manufacture, but has been targeting its efforts at the apparel manufacturing market during the last 30 years, winning over big brands like Tory Burch and Coach.

 

Apart from enabling greater design creativity and quality, the adhesives may be instrumental in helping apparel manufacturers to overcome the looming Chinese labor shortage.

ASC MEMBERS REPORT SIGNIFICANT PROGRESS MADE
ON DELIVERING VALUE FROM 2010 TO 2015

 

All Six Measures Grow from 2010; Five of Six Reach 60% Approval Ratings

 

 

December 7, 2015 – Bethesda, MD – The Adhesive and Sealant Council’s (ASC) 2015 Member Value Survey illustrates significant progress has been made in delivering value across the Council’s programs and services.

The ASC Member Value Survey, first conducted in March of 2010 and repeated in 2013, asks a series of questions about how effective the Council is in delivering value via programs and services. The 2015 survey benchmarks against both the 2010 and 2013 results, and clearly illustrates growth. Five of the six values have grown by double digits, and five of the six have eclipsed a 60% threshold for members reporting significant value.  The rating % illustrates the number of respondents that marked “Highly Effective” or “Effective” on the survey.

 

Members were asked, ‘Overall, how effectively does ASC…’

 



Survey Note:  The responses illustrated in the chart indicate the percentage of members that reported ASC was either “very effective” or “effective” when it comes to the specific value driver.


“The results of this year’s Member Value Survey illustrate how successful the ASC Board of Director’s long term path of value creation has been as these industry leaders, working side by side with committee members and staff, have spent considerable time and effort to try new things, take new directions and work hard to remain fiercely relevant to the 138 members that are part of ASC,” notes Matthew E. Croson, President of ASC.  “This energy and effort has allowed ASC to achieve regulatory wins, ensure new employees have technical training, market analysts have access to the latest data and our conventions remain a primary factor in keeping the industry connected.  It is amazing to have 90% of respondents respond favorably to ASC’s ability to connect members via networking and relationship building.  In 18 years of association management experience, I’ve never seen a 90% rating, and appreciate all of the members who have worked diligently to ensure we are creating value for our member companies.”

HB Fuller Adhesive Wins 2015 Energy and Clean Tech Award

Posted By ASC, Friday, December 4, 2015

HB Fuller’s Liquamelt® adhesive system has achieved recognition in the form of the Minnesota High Tech Association (MHTA)Tekne Award for Energy and Clean Tech, 2015. According to MHTA, the adhesive technology won the award thanks to the enhanced sustainability and efficiency it provides.

 

The commercially efficient, ‘green’ approach adhesive system can be used as a replacement for traditional thermoplastic adhesives, and does not require heating before use. This allows for improved production line efficiency including a reduction in stoppages to clean away adhesive build-up, and reduces energy consumption by up to 75%.

 

In addition, manufacturers need not order their adhesive as frequently, reducing shipping. Other benefits include greater workplace safety thanks to the elimination of hot adhesives from production processes. The adhesive itself is manufactured using 40% bio-renewable resources.

Medical Industry Looks to Adhesives Companies for Solutions

Posted By ASC, Thursday, December 3, 2015

The needs of the medical industry are varied and many. Adhesives are increasingly playing a part in the creation of innovative medical products. For instance, non-toxic adhesives that are biocompatible are being used in medical appliances, wearables and surgery. In order to assist device manufacturers, one-part epoxies with varying viscosities have been developed.

 

Medical tapes and films are also undergoing development. The films must exclude pathogens, while allowing the skin to breathe. While they must stick to skin, sometimes for periods of up to seven days, they should not adhere to other substrates such as stitches. When the film is removed, it should not damage skin. Stick-to-skin films are used to secure dressings, drug-delivering patches, monitoring devices and to support injured joints.

 

Plans to use implantable silicone chips that dissolve in time for medical use present a new challenge to the adhesives industry. Further advances as yet to be used in human trials involve the use of photopolymers to block breaches in tissues such as that of the heart using a balloon catheter. The adhesive is cured using a UV light attached to the catheter and dissolves as the tissue heals.

Auto Manufacturers Look to Adhesives Companies to Solve Practical Problems

Posted By ASC, Tuesday, December 1, 2015

Adhesives are quickly becoming the preferred bonding method for the automobile industry by enabling smaller, lighter, and stronger assemblies. With the rapid development of new composites and polymers and the need to bond materials with different rates of thermal expansion and surface-free energy (SFE), adhesives are fast becoming the preferred technology to solve complex problems and provide innovative solutions.

Cut-to-size layered adhesive films from 3M, for instance, are being used by designers to create custom parts to not only create aesthetically pleasing looks but also cut assembly times, thin out parts, and reduce overall weight.

An innovation from Fabrico allows foam blocks designed to help reduce noise and vibration to be bonded to metal parts by using laminated film. The first adhesive layer bonds to metal and a layer of aluminium foil, and a second layer of film bonds to the foil and the foam block.

Apart from requiring versatility in developing adhesives for new materials, the automotive industry also needs adhesives that will perform under a range of temperature conditions, tolerating exposure to fuel and oil. Label adhesives, for example, must be durable enough to maintain a bond under harsh conditions. In addition, foam tapes can be used to attach elements such as trim, reducing the need to drill holes in bodywork and applying rust-proofing, and providing a neater finish.

Pressure Activated Dry Powder Glue Now a Reality

Posted By ASC, Tuesday, December 1, 2015

Researchers in Japan have come up with a dry powder pressure sensitive adhesive (PSA). The technology is simple: beads of liquid latex adhesive are coated with nanoparticles of calcium carbonate to form a ‘powder’. As soon as pressure is exerted, the liquid adhesive is freed from its coating and is able to form a bond. This allows the adhesive to be poured in a dry state before it is activated.

 

As for bond strength, the team found that their powdered adhesive forms a stronger bond and is compatible with more substrates than other pressure sensitive adhesives. Researcher Syuji Fijii from Osaka Institute of Technology says that the new adhesive will be useful when bonding materials in hard to reach places creating a strong bond between intricately shaped parts.

 

He expects that the adhesive would be suitable for adoption in the automotive, aerospace and electronics industries.

Hole in the Heart? Adhesive Technology Coupled with New Device Solves Problem

Posted By ASC, Tuesday, November 24, 2015

Sealing holes in soft, flexible tissues such as the heart has proved a challenge to medical technologists. But recent advances in adhesives technology may prove to be the answer.

The biocompatible, light-curing adhesive that could solve the problem has existed for some time, but the means of applying it safely to human patients is a newer development. A team of researchers including specialists from the Boston Children’s Hospital, Harvard’s Wyss Institute for Biologically Inspired Engineering, and Harvard’s School for Engineering and Applied Sciences SEAS have found a way to apply adhesive patches with a minimally invasive procedure.

The instrument consists of a catheter with a double balloon and a fiber optic UV system. The balloons are used to apply the necessary pressure to the adhesive and the fiber optic lighting is used to activate and cure the adhesive.

At time of writing, only animal trials have been conducted, but the adhesive and the new apparatus will certainly be investigated further with the help of adhesives company Gecko Biomedical.

Crystal Clear Adhesives Improve Quality and Strength of LCD Displays and Touch Screens

Posted By ASC, Thursday, November 19, 2015

Adhesives have multiple functions. They bond materials, equalize tension and conduct electricity, but they also provide optical enhancement and re-enforcement when used on LCD displays and touch screens.

Unless screens are attached using adhesives, gaps remain around the edges. Crystal clear adhesives produce an invisible bond and improve viewing quality. They also prevent humidity and dust from affecting internal components.

Light reflection from screens is reduced by as much as two-thirds and color contrast is stronger when crystal clear adhesives are used to seal glass screens. But special crystal clear adhesives can also be used to provide improved shock resistance when combined with aluminosilicate glass.

In tests conducted by Delo Industrial Adhesives, a 13.49 lb. steel ball was dropped onto standard LCD screens and equivalent bonded glass composites from a height of 8.27 feet. Standard LCD screens shattered, but bonded glass composites made with crystal clear adhesive coatings merely bent.
