Temperature Sensitive Thermochromic Ink for Screen Printing - China Suppliers & Factory

Working Principle

The main components of thermochromic inks are microencapsulated color-changing pigments that change their molecular structure when they reach a specific temperature, thus changing their color.

Usage Method

Screen selection: High mesh mesh is usually used (such as more than 100 mesh) to ensure the fineness of the pattern.

Printing process: To print thermochromic ink uniformly on the substrate, it is usually necessary to control the thickness of the ink to ensure the best discoloration effect. After printing, it usually needs to be dried at 60°C-100°C.

Note

1. Different substrates and application scenarios may require different discoloration temperatures, and it is recommended to test before production.

2. Avoid prolonged exposure to high temperature or ultraviolet light, so as not to affect the performance of the ink.

Environment and Safety

Environmentally friendly: Thermochromic inks are usually water-based formulations that have less impact on the environment.

Safe use: Use in a well-ventilated environment to avoid contact with skin and inhalation of dust.

Storage conditions: Should be stored in a cool, dry, ventilated environment, avoid high temperature and humidity.

Through the reasonable selection and use of thermochromic inks, the application effect and quality of screen printing in the fields of smart labels, anti-counterfeiting labels and smart textiles can be significantly improved.
