Big Facts about the Optical Bonding Adhesive

Optical bonding is an important industrial process that involves using a protective glass to glue a display system. This delicate process needs a unique and reliable adhesive to be fully completed. Using this special optical bonding mechanism helps to increase the readability of the digital device.


Using optical bonding in industrial environments

Optical bonding adhesives are used to join a protective screen cover on an LCD panel. The adhesives are used to glue this protective layer over the display panel. As a protective layer, it helps to get rid of air gaps in the display unit. This way, the screen will be highly visible. Optical bonding adhesives are used in any application that requires superior optical bonding. Examples of such applications include marine, defence, electronic, and automotive applications.

There are different types of optical bonding adhesives

Optical bonding adhesives can be applied in various optical bonding applications. When it comes to the industrial use of these special glass adhesive systems, there are three most common options. These are Epoxies, polyurethanes, and silicones.


Silicon optical bonding adhesives are used mostly for this application

Silicon optical bonding adhesives are the most common industrial glue for optical bonding. This adhesive has special properties such as chemical reactivity and low conductivity. This special adhesive also easily repels water to create watertight seals. This is why it is used commonly as optical bonding adhesive. In addition, because silicon adhesive for glass bonding is made up of a soft material, it is possible to rework them over time when the bond becomes weaker.


Epoxy optical bonding adhesives have more rigidity than the silicone-based variants

Epoxy optical bonding adhesives are engineered glues that are used for optical bonding. They are applied in industrial environments due to their structural properties. Epoxy adhesives for optical bonding usually produce more rigid bonds in comparison to silicone. Epoxy optical bonding glues are stronger than silicone types because of their structural properties. Epoxy adhesives prevent the creation of particulate debris – a common feature of silicone bonding adhesives. However, it is not possible to rework epoxy bonding adhesives once they are fully cured.


The basic idea behind optical bonding processes

Optical bonding involves the use of optical-grade adhesives for glueing glass to the surface of a display system. Optical bonding is not applied to attach two materials. The idea behind this special type of bonding is to enhance the display performance of the digital product when used in outdoor conditions. This is a special type of industrial bonding process that is applied in the glass industry. It is a method that gets rid of the air gap between the display and the cover glass. To increase the readability function of the display system.


Why is optical bonding adhesive important for producing display systems?

Optical bonding adhesives are very important engineering glues with special qualities. Rather than bind two surfaces together, they also work to enhance the readability of the display. Without optical bonding adhesives, the display will be normal. When such displays are used in outdoor environments, it can be difficult to read them. Such display systems are easily surrounded by condensation or fog – which forms around the inner surface of the screens. Another problem with normal display systems is the formation of mirror images. Thanks to specially engineered adhesives, the use of optical bonding can help solve these problems.


The use of the anti-reflective coating in optical bonding processes

Anti-reflective coating is a phenomenon that is usually applied in the optical glass bonding process. This is a special type of coating that is also known as an anti-glare coating. This is a distinct optical coating process that is used in glueing the surfaces of lenses and many other optical elements. This special process is used to reduce reflection during the use of the device. Anti-reflective coating is applied in typical imaging systems to improve efficiency as it helps to minimize the amount of light lost as a result of reflection.


Optical bonding is used for increasing the contrast ratio of the display

Optical bonding is a technical bonding process that is used to increase the visibility of digital lens systems. Display readability can be a problem in outdoor conditions due to its contrast settings. Optical bonding is used to increase the contrast ratio of the display system. It does this by reducing the total amount of ambient light reflected.



The benefits of optical bonding with the best adhesives

The optical bonding adhesive is a special engineering glue that can be used to achieve a wide range of benefits. Without the optical bonding adhesive, it will be difficult for this process to be achieved completely. Optical bonding comes with the following benefits:

Increases product ruggedness: With optical bonding adhesives, a special bonding is created. When it is used to bond a glass sheet onto a display system, this increases the robustness of the display system.


Enhanced durability: The optical bonding adhesive creates a sealed display that easily resists all types of unwanted agents on the display system. A display that is a result of the optical bonding can easily resist dirt, stains, fluids, and scratches.


Condensation: The optical bonding adhesive help to bond the product to prevent condensation. This bond gets rid of air gaps that usually form between the display and the cover glass. This means that the moisture can never penetrate and create fogging on the surface of the display.


Extend the temperature range: The use of optical bonding adhesives can be used to create a display product with extended temperature ranges.

How to select the right optical bonding adhesive for your local production facility

To choose the right optical bonding adhesive for your industrial application, you need to what properties to look out for. You must choose the right adhesive as this will go a long way to help you achieve the right results. Some of the important properties to look out for when selecting optical bonding adhesives include:

  • It should have excellent optical transparency
  • It should come with a high thermal stability
  • The adhesive should have a stable UV degradation value
  • It should be able to prevent yellowing when exposed to certain conditions
  • The right adhesive should have the right refractive index, hardness, viscosity, and adhesion according to the technical sheet.
