OPTAlphaGEL Catalog

Product catalog summary

Product Overview

The document describes silicone-based optical gel products (N100SP, K120E, K95E) manufactured by Taica Corporation, designed primarily for use in LCD and touch panel applications. These gels are applied between protective panels (such as PMMA or reinforced glass) and LCDs to improve display performance and durability.

Applications

Used between protective panels and LCDs in mobile phones, digital photo frames, portable DVD players, and other display devices.
Enhances visibility, luminance, and reduces parallax in LCDs.
Improves shock absorption and stress relaxation, contributing to device durability.
Supports reworkability due to different adhesibility on each side of the gel.

Product Specifications

Thickness Ranges: N100SP: 0.2 to 1.8 mm (increments of 0.1 mm between 0.2 to 1.0 mm); K120E: 0.175 to 1.0 mm; K95E: 1.1 to 1.8 mm.
Widths: Liner width 500 mm; gel coating width 480 mm; effective width varies with thickness (460 mm for 0.175–0.5 mm, down to 400 mm for 1.1–1.8 mm thickness).
Lengths: 50 m for thinner gels (N100SP 0.2–1.0 mm, K120E 0.175–0.5 mm); 25 m for thicker gels.
Core Sizes: 3 or 6 inch cores depending on product and thickness.

Handling and Processing Recommendations

Vacuum lamination is recommended for applying the gel; users should contact the manufacturer for detailed lamination methods.
Consultation is advised for cutting procedures of the gel.
The gel is supplied with a liner on one side for ease of handling.

Performance Characteristics

Optical Improvements: Using the gel improves luminance by approximately 8-9%, reduces reflection losses (~4%), and enhances contrast by reducing sunlight reflection.
Shock Absorption: Ball drop tests show a shock absorbing rate of over 90% across various environmental conditions (high temperature, humidity, heat cycling, light resistance, low temperature).
Environmental Stability: The gels maintain transmittance and peel strength after 1000 hours of environmental testing including temperature and humidity cycling.
Reworkability: The gel can be delaminated without glue residue, facilitating repair or replacement.

Material Properties

Silicone-based gel containing low molecular siloxane, which may be volatile.
Potential silicone oil bleeding requires users to conduct reliability tests before market delivery.
Not recommended for medical applications, especially implantation.
Physical properties include specific gravity, needle penetration, Young's modulus, refractive index, and peel strength measured against various substrates (glass, PMMA, PC, PET, polarizer).

Limitations and Warnings

Products are sold without any warranty or guarantee, including implied warranties of merchantability or fitness for a particular purpose.
Users assume all risks and liabilities associated with product use.
Silicone oil bleeding and volatility of low molecular siloxane require pre-market reliability testing by users.
Use in medical or implantation applications is strongly discouraged.

Additional Notes

Copyright and trademark protections apply to the brochure content and product images.
Contact information for Taica Corporation is provided for inquiries regarding lamination, cutting, and other technical support.
