ST-EC800 Electrochromic Coatings
product presentation ：
The ST-EC800 is a high-performance electrochromic coating that enables reversible color changes under electric field. It features rapid response, long cycle life, high optical contrast, and low energy consumption. This coating is ideal for smart windows, anti-glare rearview mirrors, e-paper, and flexible display devices, making it an excellent material for intelligent and energy-efficient photoelectric control systems.
use ：
Intelligent dimming glass (used in architecture, automotive, aircraft windows, etc.);
Anti-glare rearview mirrors (for cars, motorcycles, helmets, etc.);
Electronic paper and flexible display;
Wearable device display module;
Smart tags and dynamic advertising screens;
Optical camouflage and anti-counterfeiting devices.

Construction process recommendations:
Substrate preparation: Ensure the substrate surface is clean and dry. Plasma or UV cleaning is recommended.
Coating method: Spin coating or scraping is recommended, with the wet film thickness controlled at 5-15 μm.
Drying and curing: pre-drying at 80°C for 5 minutes, followed by curing at 120°C for 30 minutes.
Electrode integration: Compatible with electrodes such as ITO, silver nanowires, and conductive polymers.
Encapsulation recommendation: Use UV-curing adhesive or epoxy resin for encapsulation to prevent moisture and oxygen ingress.
Driving test: Perform color switching tests using a DC power supply ranging from ±1.5V to ±3V.
