自動車メーカーが認めるSilicone OCA。OPTαGEL 自動車メーカーが認めるSilicone OCA。OPTαGEL

Silicone OCA (Optical Clear Adhesive) OPT Alpha GEL provides the long-lasting quality required in the automotive industry. This soft, yellowing resistant material allows for re-working of bonding defects and is available in a variety of thicknesses (max 1.8 mm). Taica proposes total optical bonding solutions to our customers, including advice regarding bonding and die cutting.

Characteristics

●Silicone OCA
Made of high-grade silicone, this OCA boasts superior physical properties, providing more stable performance than standard acrylic materials.Compared to liquid bonding materials, OCA is much easier to handle.
●Long-term Reliability
OPT Alpha GEL shows minimal yellowing when exposed to heat and UV radiation. It has low temperature dependence, allowing OPT Alpha GEL to thrive at a wide range of temperatures.
●Elasticity
OPT Alpha GEL retains elasticity and reduces stress on display components at a wide range of temperatures. This contributes to a more uniform displayed image and improved shock resistance.
●Transparency
OPT Alpha GEL is highly transparent, improving display brightness and contrast.
●Reworkability
Displays can be reworked after bonding with OPT Alpha GEL, improving yields and reducing cost.
●Thickness Line-up (max 1.8mm)
OPT Alpha GEL is available in thicknesses between 0.175 mm and 1.8 mm.

Application Example

Inserting OPT Alpha GEL between an LCD unit and the cover lens has many benefits, such as improved shock resistance, stress mitigation, increased contrast, reduced parallax, and improved luminance.
