|Dow launches next generation of silicone optical bonding materials for automotive, consumer displays at CES Asia|
|Innovator in silicone technologies adds two new DOWSIL™ VE Series products enabling improved readability, increased ruggedness and extended device life|
|SHANGHAI – June 11, 2019 – Dow Performance Silicones, a global leader in silicones, silicone-based technology and innovation is unveiling at CES Asia 2019 (booth N1-1014) two new optical bonding solutions for automotive and consumer displays exposed to harsh environmental conditions. They include DOWSIL™ VE-2003 UV Optical Bonding Material, designed to bond a glass or plastic display cover and touch panel to the LCD or OLED display module, and DOWSIL™ VE-4001 UV Electrode Protective Resin, which protects electrodes on the display module.
“As interactive displays in connected vehicles play an increasingly vital role in safety, navigation and entertainment, consumers expect an exceptional user experience,” said Jayden Cho, global consumer marketing segment leader, Dow Performance Silicones. “These displays must sustain their performance over the vehicle lifespan, under the demanding conditions of automotive interiors. DOWSIL™ VE Optical Bonding Materials deliver better readability, visibility and reliability compared to traditional organic materials, support new designs and easily adapt to existing optical bonding processes. Dow will continue to address our customers’ demands for higher-performing optical bonding solutions to meet the requirements of tomorrow’s increasingly sophisticated displays.”
These robust silicone-based materials represent the newest generation of DOWSIL™ VE Series optically clear resins, whose excellent optical properties help automotive and consumer displays deliver exceptional performance. Their benefits include high transmittance, low haze, minimal yellowing and superior reliability, even when subjected to temperature extremes, high humidity and prolonged UV exposure.
The automotive display market is projected to grow at a CAGR of over 10 percent through 2025, with 350 million units globally expected to ship by that date.1 Top design trends include the integration of touchscreens, larger displays, curved screens and heads-up displays.
Reliable Optical Bonding
In direct response to this challenge, Dow developed the new DOWSIL™ VE Series materials. DOWSIL™ VE-2003 UV Optical Bonding Material is a transparent, solventless, one-part UV-curable solution used to bond a cover window and touch panel made from glass or plastic, such as polymethyl methacrylate (PMMA) or polycarbonate (PC), to the display module. It is engineered to resist degradation and yellowing from ultraviolet (UV) exposure and from high and low temperature extremes and humidity. The material delivers consistent optical transmittance greater than 99 percent before and after reliability testing.
DOWSIL™ VE-2003 UV Optical Bonding Material offers excellent adhesion, self-leveling flowability, low modulus to avoid mura effect, and low shrinkage (less than 1.0 percent) for dimensional stability – especially in larger displays. It can cure to an extremely soft material which helps provide cushioning and stress relief for delicate components.
Benefits of an All-silicone Solution
To offer the industry a compatible, silicone-based EPR for use with DOWSIL™ VE-2003 UV Optical Bonding Material, Dow developed DOWSIL™ VE-4001 UV Electrode Protective Resin. This new solution offers high reliability including consistent hardness and adhesion before and after testing, thanks to its low volatility. The cured material provides stress relief for sensitive components.
DOWSIL™ VE-4001 UV Electrode Protective Resin is a translucent, one-part, UV-curable silicone resin designed for liquid-based bonding processes and is available worldwide.
