Temperature Sensitive Thermochromic Ink for Screen Printing - Top China Suppliers & Factory
Product peculiarity
Color change
Thermochromic inks can change from one color to another, or from colored to colorless, depending on temperature changes. This change can be reversible (return to primary color after temperature reduction) or irreversible (permanent discoloration).
Environmental protection
Usually water-based formula, friendly to the environment.
Flexibility
The printed coating has good flexibility and is suitable for use on flexible substrates such as fabrics.
Durability
The printed pattern has good washable resistance and wear resistance.
Customization
Different color change temperature ranges (e.g. 0°C to 70°C) can be customized as required.
Application field
Smart labels
Smart labels for the packaging industry that can be used as anti-counterfeiting labels or functional coatings.
Smart textiles
Used for printing smart textiles, such as sportswear, outdoor equipment, etc.
Anti-counterfeiting mark
Used to make anti-counterfeiting mark to improve product security.
Temperature indicator
Used to make temperature indicator labels, such as cold drink indicators on beverage cans.
Educational tools
Thermochromic inks are also used as educational tools because of their unique color-changing properties.
Product Details
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. The specific principles are as follows:
Reversible discoloration: When the temperature rises, the molecular structure of the pigment changes, and the color disappears or changes; When the temperature drops, the molecular structure recovers and the color reappears.
Non-inverting color: Some thermochromic inks have a permanent color change after reaching a specific temperature and are often used for temperature monitoring or warning labels.
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
Different substrates and application scenarios may require different discoloration temperatures, and it is recommended to test before production.
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.
Frequently Asked Questions
How does thermochromic ink change color?
Thermochromic inks contain microencapsulated color-changing pigments. When these pigments reach a specific temperature, their molecular structure changes, causing the ink to transition from one color to another, or from colored to colorless.
What is the difference between reversible and irreversible thermochromic ink?
Reversible thermochromic ink returns to its original color once the temperature drops back down. Irreversible (non-inverting) thermochromic ink undergoes a permanent color change after reaching its threshold temperature, making it ideal for safety and warning labels.
Can the color-changing temperature threshold be customized?
Yes, the activation temperature ranges can be customized according to your project requirements, typically anywhere from 0°C to 70°C.
What is the recommended printing process for this ink?
Screen printing is highly recommended using a high mesh screen (above 100 mesh) to ensure a fine pattern. After printing, the ink coating should be dried at temperatures between 60°C and 100°C.
How should thermochromic inks be stored?
They should be stored in a cool, dry, and well-ventilated environment. It is crucial to avoid high humidity, high temperatures, and prolonged exposure to direct ultraviolet (UV) light to protect the ink's performance.
Is thermochromic ink environmentally friendly and safe to use?
Yes, our thermochromic inks are water-based formulations, making them eco-friendly. For safety, they should be applied in well-ventilated areas while avoiding direct skin contact or inhalation of dust.
