Description
Irreversible Thermochromic Pigment: High-Temperature Warning and Indication
Ensure safety and monitor critical temperature thresholds with our irreversible thermochromic pigment. This unique pigment provides a permanent colour change at 60°C (140°F), making it ideal for a variety of high-temperature warning and indication applications.
Versatile Applications
This pigment can be incorporated into a range of mediums to create temperature-sensitive products and applications:
- Inks: Develop irreversible thermochromic inks for screen printing, marking, and other applications.
- Paints: Create irreversible thermochromic paints for surfaces that reach high temperatures.
- Resins: Formulate irreversible thermochromic resins for casting, moulding, and other creative applications.
- Plastics: Incorporate the pigment into plastics through injection moulding to produce temperature-sensitive products.
How It Works
This pigment is black at temperatures below 60°C. Once the temperature exceeds 60°C, it undergoes an irreversible transformation, becoming translucent. This permanent colour change serves as a clear visual indicator that a specific temperature threshold has been reached or exceeded.
Key Features
- Irreversible Colour Change: Provides a permanent visual record of temperature exposure.
- High-Temperature Activation: Specifically designed for applications requiring monitoring above 60°C.
- Versatile Applications: Suitable for plastics, labels, coatings, and more.
- Easy to Incorporate: Compatible with various mediums, including water-based and solvent-based systems.
Applications
- Safety Labels: Create hot warning labels for machinery, equipment, and surfaces that reach high temperatures.
- Process Monitoring: Verify that materials have reached the correct curing temperature during manufacturing processes.
- Temperature Indication: Monitor temperature thresholds in diesel engines, food transportation, and other critical applications.
Technical Details
- Particle Size: Approximately 20µm
- Mixing Ratio: Combine with a water-based screen printing binder or sprayable lacquer at a 10% to 90% ratio.
- Compatibility: Compatible with both solvent and water-based mediums.
