Master Bond offers the display industry a broad and sophisticated range of adhesive solutions. These systems are formulated for applications requiring durable and transparent bonds. Non-yellowing, optically clear adhesives designed for electronic display components help to protect the integrity of critical display components, enhancing both aesthetic and practical functionality.
The Master Bond product line includes both one and two component epoxy resin compounds and one component UV curable compositions. The epoxy resin compounds are all specially formulated to maximize resistance to liquid water, water vapor and other adverse environments. Some of the outstanding features of the optical systems offered by Master Bond are excellent light transmission characteristics, superior non-yellowing properties along with a wide range of systems where the index of refraction ranges from a relatively low 1.43 up to 1.61. It should be noted that the ultraviolet compositions cure tack free in the presence of air. All Master Bond products have been carefully processed to exclude such potentially objectionable contaminants as chlorine and other halogens as well as sodium and related elements. They provide innovative solutions to the many processing problems of these industries and virtually eliminate quality control difficulties caused by corrosion and other environmentally induced conditions.

Custom Formulations
The many potential applications of display adhesives make for a very complex selection process; one requiring much research of all relevant considerations. It is for this reason that Master Bond Inc. offers custom formulated solutions; tailor-made products possessing those properties necessary for successful adhesive employment. Regardless of the application requirements, adhesive formulations may be adjusted to possess all required characteristics. Noteworthy are systems boasting cryogenic serviceability, superior thermal conductivity, high chemical and temperature resistance, vibration, impact and shock resistance, low shrinkage and low-stress properties. Special grades are NASA low outgassing approved. Master Bond optical adhesives exhibit excellent light transmission characteristics, and superior now yellowing properties. Additionally, a range of systems with a wide index of refraction indices from a relatively low 1.43 up to 1.61 is available. Processing requirements such as cure speed and viscosity may also be altered for optimal system compatibility and performance.
Master Bond Optically Clear Systems for Display Applications
Optical clarity is one of the many important properties a display industry epoxy may require. Much investment of research and development has yielded a high-end line of optical adhesives, boasting optical clarity, and specially formulated for reliable performance in the potentially trying climates of electronic devices. Specially optically clear compounds offer service temperatures from as high as 600ºF (300ºC) to as low as cryogenic temperatures (4K). Spectral transmission ranges from 300 nanometers to in excess of 2000 nanometers are available. Typical optical transmission measurements in the most widely used 300-400 nanometer range are greater than 90%. In addition, these optically transmissive compounds exhibit excellent long-term stability and exceptional resistance to unfavorable environment exposures including moisture.
