What is an indium mirror coating system?
The indium mirror coating system is a dedicated coating process optimized for forming indium-based high-reflectivity mirror films. The standard process consists of a 3-coat, 3-bake structure (repeating application and drying three times), and the management of film thickness, heating conditions, and environmental control during each step significantly affects optical properties and adhesion. In particular, parameters such as the concentration of fine particles, temperature and humidity, and electrostatic environment within the painting booth influence the final film quality (reflectivity, durability), making the formation of the coating in a clean and stable environment extremely important. **Features and Benefits of Indium Mirror Coating** - A new metal color spray method that achieves reduced environmental impact: A coating system using spray painting technology as a replacement for traditional plating processes. - Compatibility with various materials: Forms a highly adhesive and uniform film on various substrates such as stainless steel, resin, and glass. - Excellent radio wave transmission characteristics: Equipped with radio wave transmission performance suitable for radar and communication devices, differing from optical high-reflectivity films, making it ideal for sensor-related applications. - Automation compatibility and multilayer coating: Can be integrated into automated lines in conjunction with Takubo's painting robots. Durability can be adjusted through multilayering from the base layer to the protective layer.
basic information
The indium mirror coating system is a dedicated multilayer coating process developed to achieve a high-reflectivity mirror film primarily composed of indium. The process consists of 3 coats and 3 bakes, where each layer undergoes application → drying → heat curing (bake) to form a coating with excellent adhesion, heat resistance, and optical performance. ■ Bake Conditions (Reference Values) ProcessTemperatureTimePurpose 1st Bake (after primer): 80–100 ℃10–15 minutesSolvent evaporation and mild curing of the base layer 2nd Bake (after intermediate coat): 120–150 ℃15–20 minutesStrengthening adhesion of the intermediate layer and improving smoothness 3rd Bake (after top coat): 150–180 ℃20–30 minutesComplete curing of the final film and stabilization of mirror finish *Conditions can be adjusted according to the heating method (hot air circulation / infrared / gas type, etc.) and work material. ■ Environmental Management Requirements (Recommended) Cleanliness: Class 10,000 (ISO 7) or better Temperature: 22–26 ℃ Relative Humidity: 45–60 % Static Electricity Measures: Conductive flooring and ionizer installation recommended *For more details, please refer to the materials.

|---|---|
| 3R3C Line Dancer 4gun 8top | This is a painting system consisting of three robots, each responsible for one coat. It has a short movement time, high productivity, and is suitable for mass production. It features a 3R3C line dancer with a four-gun, eight-top automatic painting system (for mass production). Each robot is equipped with four guns, and the transport device (table) has eight tops. |
| 3R3C Swampro 2gun 4top | Three robots will handle three coats (one robot per color). It is a compact type of semi-mass production system for plating and painting. The Swan Pro is a standalone autonomous robot, and the transfer is managed by a double turntable equipped with the Swan Pro. It is separated from the conveyor, and the painting object transport device, Co_Swan, is responsible for handling, which keeps the line clean and prevents defects in painting such as spots. This is the 3R3C Swan Pro 2-gun 4-top automatic painting system (for semi-mass production). |
| 1R3C Line Dancer Turret 3Gun 4top | A single robot processes three coats (one robot, three colors). It is a production line for small lots and a variety of products with plating and painting. It is equipped with a turret gun unit that can be fitted with three guns, allowing for quick color changes. This is a compact painting system. 1R3C line dancer with a 3-gun turret and 4-top automatic painting system (for small lots and a variety of products). One robot is equipped with three guns and a conveyor device (table) with four tops. |
| 1R3C Swampro Turret 2Gun 4top | - Batch painting system: A batch painting system that processes 3 coats (3 colors with 1 robot). After each coat, it goes to a drying oven operated by a worker. This system is designed for small-scale production and helps to keep initial costs down. 1R3C Swan Pro 2 Gun Turret 4 Top Batch Painting System (for small quantity and diverse products): Equipped with 2 guns on 1 robot and a conveying device (table) with 4 tops. |
