Epoxy liquid optically clear adhesives glue for touch screen panels and display devices to bonding the cover lens and plastic
Recently, optically clear adhesives are one of the most necessary elements for various touch screens and electronic appliances. It stands true across numerous industries.
These substances or products come into application for several optical bonding uses. They allow for curved and free-form display designs.
Optically clear adhesives make the best choice for applications that demand sturdy contact bonding and transparency. On top of that, they help safeguard sensitive electronic parts and bond dissimilar substrates. They can do so efficiently, quickly, and conveniently.
In this article, let us discuss further optically clear adhesives.
What are the Varying Types and Categories of Optically Clear Adhesives?
Optically clear adhesives can get classified into varying types depending on their composition and application. These types consist of the following:
• Liquid Optically Clear Adhesive (LOCA)
LOCA serves as a suitable choice of adhesive for touch panels, display screens, and other bonding applications related to the lens. They can secure the required components in place securely. On top of that, it allows for a sturdy bonding on substrates and plastic structures for automotive displays, mobile phones, etc.
Liquid optically clear adhesive (LOCA) is liquid-based bonding technology used in touch panels and display devices to bind the cover lens, plastic, or other optical materials to the main sensor unit or each other. These adhesives improve optical characteristics and durability. LOCA glue is often hardened using ultraviolet light.
LOCA primarily gets used for automotive applications.
• Acrylic Optically Clear Adhesives
Acrylic optically clear adhesives possess a liquid form. Nevertheless, they get made using acrylic adhesives instead of silicone. Their high resistance to haze makes them suitable for electronic uses such as touch and display screens.
• Epoxy Optically Clear Adhesive
Epoxy optically clear adhesive uses a purely UV-curing method. It can get attached to different and distinct substrates. These adhesives have high thermal resistance and low shrinkage. It allows the epoxy optically clear adhesives to get used for lens bonding purposes.
• Optically Clear Resin (OCR)
OCR has a liquid form and can get injected into the required area during application. It is highly suitable for various printable materials. These adhesives typically get used for video display and touch screen applications. It can be because of the need for high environmental factors resistance and secure bonding.
What are the Diverse Industrial Applications of Optically Clear Adhesives?
Optically clear adhesives are an exceedingly essential material used in a broad range and scope of products these days. A few industries where they find applications comprise the following:
• Optical
Optically clear adhesives get used in the optical industry for lens bonding, fiber array assembly, MUX, DEMUX, PLC, and photonics design using silicone in optical transceiver systems. It can also do so for the entire assemblage.
Different values or measurements of refractive index and suitable transparency remain necessary for matching distinct substrates with a light patch and refractive index.
• Automotive
In the automotive industry, optically clear adhesives get used to secure the displays and screens to their consoles. On top of that, they get utilized for various design types.
• Electronics
Optically clear adhesives play a significant role in the electronics industry with the advent of various touch screen devices and products. They require advanced adhesive uses and solutions to hold the screens in place. In addition to that, they protect the entirety of the product.
