Thermochromic Liquid Crystal Paint Multicolor Mood Color KT-MLC01

The color sequence in KT-MLC01 is fixed by the liquid crystal pitch — not adjustable post-manufacture. Each temperature step produces a specific hue, and the transitions are reversible. The full sequence:

Code	Mood Liquid Colors	Form
KT-MLC01		Liquid

The black-to-black cycle means the material appears neutral at both low and high temperature extremes, with the full chromatic sequence visible only within the active band. In practice, this makes the effect most legible on dark or black background coatings, which suppress competing reflectance during the off-state.

Product Series Context

KT-MLC01 sits within Kolortek's broader thermochromic pigment range. For reference, the other series address different transition needs:

That said, KT-MLC01 is not a substitute for the powder-based KTP series when a discrete binary transition is needed. The liquid crystal format produces a gradient, not a clean on/off switch — which is either an advantage or a limitation depending on the application requirement.

Applications

The liquid form of KT-MLC01 lends itself to formulations where direct dispersion into a water-based carrier is practical:

• Custom decorative paints: Applied over a black base coat, the full color sequence is visible as surface temperature shifts — relevant for interactive wall treatments or novelty product finishes.
• Textile printing: Compatible with water-based print systems used in fabric decoration; the active temperature band (16℃–34℃) aligns with typical skin-contact conditions.
• Cosmetics: Usable in formulations where temperature-responsive color shift is part of the design — body paint, nail effects, or similar formats.
• Printing inks: Suitable for screen or flexo processes using water-based vehicles.

Worth noting: KT-MLC01 is not recommended for automotive coatings or solvent-heavy systems where the liquid crystal encapsulation integrity may be compromised.

Practical Formulation Considerations

A few points that matter in actual use:

• Background layer matters: Liquid crystal pigments reflect light rather than absorb it. On white or light substrates, the color contrast will be significantly weaker. A black or very dark undercoat is essentially mandatory for legible color shift.
• UV sensitivity: Like most thermochromic materials, prolonged direct UV exposure degrades performance over time. For outdoor applications, a UV-protective topcoat should be considered.
• Temperature range is fixed: The 14℃–36℃ active window is inherent to this formulation. If a different activation range is needed, that requires a different product — custom development, not a field adjustment.
• Dispersion: The liquid format integrates more easily into water-based systems than encapsulated powders, but shear mixing should be kept moderate to avoid mechanical damage to the liquid crystal structure.
• Laydown rate: Coating film thickness influences color intensity. Thinner layers will produce a more transparent, less saturated effect; this can be used intentionally for translucent finishes.

FAQ

Q: Can the activation temperature range of KT-MLC01 be adjusted?
No. The color-response window of this liquid crystal formulation is fixed at 14℃–36℃. Modifying the active range requires a different liquid crystal pitch, which is a manufacturing-level parameter. If your application requires a different temperature window, contact contact@kolortek.com to discuss custom development options.

Q: Is KT-MLC01 the same product as the KTP thermochromic pigment powders?
No. KT-MLC01 is a liquid-form thermochromic liquid crystal that produces a continuous multi-color shift across a temperature range. The KTP series are encapsulated powder pigments designed for discrete single-transition color changes (color-to-colorless or color-to-color). They serve different formulation needs and are not interchangeable.

Q: Is KT-MLC01 suitable for food-contact applications?
No. For food-contact items such as cups, spoons, or similar products, the Food Grade BPA-Free series (KTP-xxBF) is the appropriate choice. KT-MLC01 is not designated for food-contact use.

Q: What substrate systems are compatible with this material?
KT-MLC01 is a water-based liquid and is primarily suited for water-based coating, ink, and print systems. It is not intended for solvent-based or UV-cure systems where the carrier chemistry could compromise the liquid crystal encapsulation. Compatibility testing in your specific formulation is recommended before scale-up.
