Slurry, Pigments, and Inks to Create Custom Solutions
Advanced thermochromic materials engineered to deliver precise, visible color-change solutions for your unique temperature-monitoring application.
Irreversible Thermochromic Technology
A high-temperature activated, water-based ink or pigment that permanently changes from colorless to color once a critical threshold is reached – with color density increasing as temperature rises. Built on SpotSee’s Leuco Dye technology and available as flexo ink, screen ink, or aqueous concentrate. Temperature range: 60°C to 200°C.
Use: metal fabrication and annealing verification, process quality control, surface temperature monitoring, security and warranty labels, and high-temperature safety and engineering alerts.
Thermochromic Masterbatch Applications
Temperature-sensitive pellets containing encapsulated Leuco Dyes that change from colored to colorless as temperature rises – and revert when cooled. Engineered for direct use in plastic manufacturing, with a color-change differential of approximately 5°F across a broad activation range.
Available in 11 colors. Temperature range: -10°C to 69°C (14°F to 156°F). Compatible with PP, PE, HDPE, LDPE, PVC, EVA, PS, and SAN.
Use: color-changing cups, spoons, bowls, and stirrers – consumer or industrial plastic product where a built-in temperature cue adds engagement or safety value.
PHOTOCHROMIC INKS, DYES & MASTERBATCH
Color-change materials that activate in response to UV light – shifting from clear to color outdoors or under a black light, then reverting when the light source is removed. Available in both reversible and irreversible formulations, and compatible with virtually any manufacturing or printing process.
Available as: dyes, microencapsulated slurries, powders, screen inks, labels, and masterbatch pellets for plastic injection molding and extrusion.
Use: apparel, packaging, cosmetics, footwear, glassware, security labels, novelty products, and industrial UV-exposure indicators.
MICROENCAPSULATION
The process that makes liquid crystal and Leuco Dye materials practical for real-world use – converting difficult-to-handle internal phases into stable, water-based forms. Each droplet is individually encased in a protective wall, shielding it from environmental degradation, preventing crystallization, and enabling consistent print and coating performance.
Microcapsules of different formulations can also be blended to produce multi-color temperature responses in a single coating or film.
Used for: all SpotSee liquid crystal slurries, Leuco Dye concentrates, thermochromic inks, and pigment-based products.
THERMOCHROMIC LEUCO DYES
Color-change materials that shift from colored to clear – or clear to colored – as temperature fluctuates, reverting automatically when conditions change. Available under SpotSee’s Chromazone (reversible, -10°C to 69°C) and Kromagen (permanent, 50°C to 200°C) product lines in slurry, powder, dye, ink, and masterbatch forms.
Activated by cold, touch, or high heat depending on formulation.
Used for: quality and process control, product labeling, packaging, promotional graphics, toys, and any application where a dynamic, cost-effective visual temperature cue adds value.
LIQUID CRYSTAL THERMOMETERS
Self-adhesive, reversible temperature indicator labels containing microencapsulated thermochromic liquid crystals (TLC) on a black backing. Each element passes through the visible spectrum – tan to green to blue – with green indicating the exact temperature. Accurate to ±1°C, reusable indefinitely, and available in custom sizes, shapes, temperature ranges, and graphic designs.
Temperature range: -30°C to 120°C (-22°F to 248°F).
Used for: forehead and aquarium thermometers, industrial thermal mapping, medical devices, propane level indicators, and promotional applications.
CONDUCTIVE & THERMOCHROMIC INK
A functional printing solution that combines printed conductive circuits with thermochromic color-change displays on thin, flexible plastic substrates. When the circuit is electrically charged, heat triggers a calibrated color change – enabling battery-powered visual displays, indicators, and custom messages without traditional screens or components.
Available in numerous colors with fully custom designs.
Used for: battery capacity indicators, product displays, smart packaging, interactive labels, and any application requiring a printed, powered color-change element.
LIQUID CRYSTAL FORMULATIONS
Highly temperature-sensitive thermochromic materials that cycle through red, green, and blue as temperature rises – reversible, reusable, and accurate to ±0.5°C. Available in standard RGB, single-color-below, and single-color-above configurations to suit a wide range of indicator designs. Fully customizable in size, shape, and temperature range.
Temperature range: -30°C to 120°C (-22°F to 248°F). Shelf life: 12 months.
Used for: healthcare and forehead thermometers, fridge and aquarium monitors, cold chain control, gas level indicators, industrial thermal mapping, and foot pressure analysis.
