HuiZhou StarColor Water Based Ink

【Product Overview】 This temperature-sensitive color-changing screen printing ink utilizes microencapsulation technology, allowing the ink to change color in response to changes in ambient temperature. When the preset trigger temperature is reached, the ink quickly switches between "colored" and "colorless" or "two colors." Its screen printing formula ensures sufficient ink layer thickness, resulting in a fuller and more intuitive color-changing effect. 【Common Color-Changing Modes】 Low-Temperature Color Changing: Used for labels on cold drinks and beer (e.g., displaying a specific pattern when refrigerated below 10°C). Touch-Sensitive Color Changing: Used for gift boxes and business cards (color changes when touched at approximately 31°C). High-Temperature Warning: Used for burn prevention warnings or industrial safety (e.g., color-changing reminder above 50°C). 【Main Application Scenarios】 High-End Beverage Labels: Monitoring refrigeration temperature and increasing consumer interaction. Creative Gift Boxes: Hidden patterns with a sense of mystery, revealed by touch with body temperature. Security and Anti-Counterfeiting: Utilizing specific color-changing temperature points as a difficult-to-counterfeit brand identifier. Daily Necessities: Color-changing cup stickers, stationery, clothing printing, etc. 【Core Technological Advantages】 **Sensitive and Precise Response:** The color-changing temperature difference is controlled within ±2°C, ensuring a smooth and seamless color-changing process. **Excellent Screen Printing Adaptability:** The ink layer is uniform and full, with strong coverage, suitable for 150-300 mesh screen printing without clogging. **High Color Contrast:** The visual difference before and after color change is significant (e.g., from deep blue to colorless), facilitating visual identification. **Good Adhesion:** Performs excellently on treated PP, PET, PVC, and various coated papers. **Safe and Non-Toxic:** Environmentally friendly formula, passing relevant safety standard tests, suitable for food packaging. 【Technical Parameter Reference】 **Trigger Temperature Points:** Standard 31°C (hand temperature), 10°C (cold drinks), 45°C (high temperature), etc., customizable upon request. **Color Change Types:** Color to colorless, colorless to colored, colored to colored. **Number of Color Changes:** Can undergo thousands of repeated color changes.
