Products and Services

• Azodicarbonamide, Hydrazide, and UNICELL-G Series: Designed for use in plastics and rubber, these foaming agents play a critical role in the production of lightweight and durable materials.
• Photoresist: A polymer compound vital for lithography, it changes under exposure to light to form specific patterns essential for semiconductor manufacturing.
• Stripper: A specialized material used to remove photoresist (PR) in the production of LCD and OLED panels, ensuring the clean elimination of PR without damaging the underlying material.
• Etchant: An acid solution used to etch away specific metals in a multilayer configuration, critical for creating microcircuit wiring within electronic devices.
• Color Resist: An organic composition containing pigments that emit red, green, and blue light, crucial for the display technologies in electronic devices.
• Background Electrode Materials: Applied to the back of electrodes, these materials enhance touch sensitivity by dispersing electricity into a conductive polymer layer, protecting internal components.
• Hard Coating Material: Provides a durable protective layer on surfaces to resist scratches and other forms of wear.
• Touch Screen Materials: Key components for the manufacture and functionality of touch-sensitive screens.
• Semiconductor Thinner: Utilized in the edge bead removal process to clean excess photoresist from the silicon wafer edges after the spin coating process.
• CMP (Chemical Mechanical Planarization): A technology that flattens the wafer surface both mechanically and chemically by applying slurry, essential for high-precision semiconductor production.
• Anti-Reflective Coating: Material that minimizes reflections and optical interference, improving the performance of optical and electronic devices.
• Spin-On-Carbon Hardmask: Serves as a hardmask during lithography for defining ultra-fine patterns on semiconductor wafers.
• Precursor for CVD/ALD: Chemical materials used as raw input for Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD) processes in semiconductor manufacturing.
• Melamine Mold Cleaner: An epoxy molding compound cleaner designed to protect semiconductor IC and diode package from impact.
• Fuel Cell Membrane Electrode Assembly: A critical component in fuel cells that contributes to energy conversion efficiency.
• Li-ion Battery Conductive Slurry: Applied to polymer batteries, this enhances conductivity and overall battery performance.
