Silicone OCA for Display Projects: A Scenario-Based Selection Guide

Silicone optically clear adhesive (OCA) is used to bond display cover glass, touch panel layers, and display panel layers into a single optical stack. Selecting the right silicone OCA requires matching its optical, mechanical, and environmental performance to the actual display project conditions. This guide examines how project requirements should drive silicone OCA selection, using the Polomo TS107, TS108, and TS109 series as a documented example.

Problem Definition: Why Project Matching Matters

Display full lamination projects are not uniform. An automotive cockpit display faces wide temperature swings, high humidity, high-altitude negative pressure, vibration, and strong UV exposure. An industrial touch display may require consistent adhesion to glass and PET, while a medical display may need low-odor, low-VOC properties for health-certified applications. If the adhesive does not fit the environment and process, common lamination defects such as bubbles, mura, and yellow spot defects can appear. The core sourcing question is therefore: which OCA properties are required by this project's environment and process?

Industry Background: Silicone OCA in Display Markets

The global optically clear adhesives market was valued at approximately USD 2.1 billion in 2024, with automotive displays accounting for around 20% of revenue, according to Verified Market Research. The automotive silicone market reached about USD 10.2 billion in 2024, and silicone-based automotive adhesives are projected to grow at a CAGR of 8.8% from 2025 to 2032. Asia Pacific accounted for roughly 51% of the automotive adhesives market in 2024. Industry references also indicate that large curved automotive displays require low-modulus silicone OCA to prevent thermal-stress-induced mura, and that UV resistance and anti-yellowing behavior are standard priorities for cockpit durability.

Company Profile

Guangdong Polomo New Materials Technology Co., Ltd (Polomo Group) is a materials company that integrates R&D, manufacturing, and sales. Founded in 2002, Polomo supplies high-performance adhesive and functional film solutions for optoelectronic displays, semiconductor packaging, energy storage/batteries, and AI-enabled smart hardware. Its manufacturing base covers 90,000 m², employs about 300 people, and has an annual output capacity of 10 million pieces; the R&D team includes 80 engineers. Around 30% of output is exported to global markets.

Core Product: Silicone OCA TS107, TS108, TS109

The silicone OCA series TS107, TS108, and TS109 is an all-climate optically clear adhesive for display full lamination. Documented parameters include:

• Thickness: 20–2000 μm
• Product size: 3–50 inches
• Appearance: colorless transparent solid
• Modulus: 22±5
• Δb: 0.03
• Haze: <0.3
• Water absorption: <0.3
• Dielectric constant (1 MHz): 2.9

According to the product specification, the series provides high transmittance and yellowing resistance; low modulus and strong degassing capability for large-size displays; weather resistance under high/low temperature, high humidity, high-altitude negative pressure, vibration, and strong UV; low odor and low VOC with low volatilization at high temperature; and adhesion to glass, PET, polarizers, and metals. The product is applicable to automotive, industrial control, medical, smart home appliances, consumer electronics, aerospace, marine, and other industries.

Manufacturing and Customization Capabilities

Polomo operates under an OBM production mode. Customization is available for thickness and dimensions. Monthly capacity is approximately 1 million pieces, with a lead time of 7–10 working days; MOQ is to be discussed. Quality control includes 100% pre-shipment testing. After-sales support includes 8D complaint handling, online and on-site production line support, root cause analysis, and continuous improvement based on customer pain points.

Step-by-Step Lamination Process

The documented operating sequence for the TS107, TS108, and TS109 series in display full lamination is: remove light release liner → STH → remove heavy release liner → HTH → autoclave. The process uses lamination equipment and requires room temperature and low-pressure conditions.

Use Cases by Application

Automotive Displays

In automotive programs, the product is used by OEMs, Tier 1 suppliers, panel manufacturers, lamination manufacturers, display terminal manufacturers, and distributors. The documented case record spans more than 10 years, with shipments exceeding 30 million pieces and application in over 120 vehicle models. Reported outcomes include improved lamination yield by 1.5%, resolution of bubbles, mura, and yellow spot defects, improved production efficiency by 75%, and improved rework efficiency by 85%. The material also meets health and safety requirements for mother-and-child-friendly smart cockpits. End-vehicle brands in the documented case base include Mercedes-Benz, BMW, Audi, Toyota, Volkswagen, Li Auto, NIO, and BYD.

Industrial, Medical, and Other Displays

For industrial touch displays and medical displays, the same material attributes—UV resistance, weather resistance, low odor, low VOC, and adhesion to glass/PET—are relevant. The product's applicable industry list explicitly includes industrial control, medical, smart home appliances, consumer electronics, aerospace, and marine applications. In health-certified environments, the low-odor and low-VOC profile supports materials qualification.
