KT-95125 Blue-green duochrome chameleon pigment

Product Overview

Chameleon pigments—also called multichrome pigments—rely on angle-dependent interference to produce multiple distinct color phases as the observer or light source moves. KT-95125 belongs to our TiO₂-free sub-series within the KT-9000 family, where the interference stack is built from iron oxide and silica layers on natural mica rather than titanium dioxide. This design addresses formulator and consumer concerns about TiO₂ while delivering a rich, high-chroma color shift.

The blue-green-to-red progression is one of the most dramatic shifts we offer. In our application lab, we see this grade most often specified for projects where the goal is maximum wow factor—automotive show cars, limited-edition cosmetics, anti-counterfeiting features, and luxury packaging that needs to stand out under both natural and artificial light.

Technical Specifications

Chemical Composition

The product is not classified as hazardous under CLP Regulation (EC) No 1272/2008, and meets heavy-metal limits typical for cosmetic and decorative-coating grades (As <2 ppm, Pb <10 ppm, Cd <3 ppm, Hg <1 ppm).

Particle Size and Visual Impact

The `25` suffix in KT-95125 indicates the 100–250 µm size bracket—the largest in our chameleon lineup. This coarse grade is designed for applications where sparkle and color travel are more important than smooth, uniform coverage. Typical use cases include:

• Automotive custom finishes and wraps where the paint needs to "pop" under changing light
• Cosmetic nail lacquers and gel polishes that demand bold, chunky glitter-like effects
• Decorative coatings on accent panels, signage, and luxury packaging
• Security and anti-counterfeiting features where the color shift serves as an authentication marker

In formulations requiring smoother appearance or higher hiding power, we offer finer grades in the same series (KT-95110, KT-95115) with particle sizes down to 5–25 µm. Larger particles scatter more light and create stronger sparkle, but they also settle faster in liquid systems and may require higher shear during dispersion.

Application Guidelines

Substrate and Formulation Considerations

Dark or black substrates are essential for maximum color shift. On white or light-colored bases, the chameleon effect becomes subtle because the substrate reflects too much white light, washing out the interference colors. We typically recommend a black or deep-colored basecoat—or, in cosmetics, formulating over a dark cream or gel base.

KT-95125 is compatible with most resin systems:

• Solvent-based coatings: acrylic, polyurethane, alkyd, epoxy
• Water-based systems: acrylic emulsions, polyurethane dispersions (ensure adequate wetting)
• Plastics: injection molding (PP, PE, ABS), extrusion, masterbatch compounding
• Printing inks: screen, offset, flexo, gravure (particle size may require coarser mesh)
• Cosmetics: nail lacquers, gel polishes, lip glosses, eyeshadows (ensure cosmetic-grade specification)

A clear topcoat is strongly recommended in automotive and coating applications to protect the pigment layer and enhance visual depth. The topcoat also helps prevent mechanical abrasion of the larger particles.

Dispersion and Mixing

From our experience supporting coating formulators, these coarse chameleon pigments require moderate shear to break up soft agglomerates but should not be over-milled—excessive grinding can fracture the mica platelets and reduce the color shift. Standard high-speed mixers or bead mills at low-to-moderate intensity work well. Add the pigment slowly to the vehicle under agitation to ensure even wetting.

You can combine KT-95125 with transparent absorption pigments (organic dyes or transparent iron oxides) to shift the base color or modify the interference hues. For example, adding a small amount of transparent blue can deepen the blue phase and suppress the red endpoint.

Series Context and Model Selection

KT-95125 is part of the KT-9000 Magic Chameleon Series, specifically the TiO₂-free sub-series (model codes KT-951xx). Other particle sizes in the same color family are available (KT-95102, KT-95110, KT-95115) for applications requiring finer texture or higher coverage. The KT-9000 series also includes TiO₂-based chameleon grades (KT-900xx models) that offer different color-shift palettes and higher reflectance.

We maintain a cross-reference program aligning our grades with major industry benchmarks, but no specific Iriodin® equivalent is mapped for this model in our published data. If you're migrating from another supplier's chameleon line, contact our technical team with your current product code and target application—we can run side-by-side color measurements and recommend the closest match.

Storage and Handling

Store containers in a well-ventilated area. Although the pigment is chemically inert and non-toxic, dust control is important during handling:

• Wear an approved dust mask covering nose and mouth
• Use gloves, safety glasses, and protective clothing (apron, boots)
• Provide adequate ventilation or local exhaust when transferring bulk material
• Avoid generating airborne dust or allowing accumulation on surfaces

First aid: In case of inhalation, move to fresh air and keep at rest. Skin contact: wash with plenty of water. Eye contact: flush with gently flowing fresh water; if irritation persists, seek medical advice.

Frequently Asked Questions

What is the difference between KT-95125 and finer chameleon grades like KT-95110?

KT-95125 has a particle size of 100–250 µm, producing intense sparkle and dramatic color travel but lower hiding power and a coarser texture. KT-95110 (10–60 µm) offers smoother appearance, better coverage, and easier dispersion, making it more suitable for applications where a refined finish is required. Both share the same blue-green-to-red color shift, so the choice depends on the desired visual texture and end-use requirements.

Can KT-95125 be used in cosmetic formulations?

Yes, provided you specify the cosmetic-grade version that meets the relevant regulatory requirements (EU Cosmetics Regulation EC 1223/2009 or US FDA color-additive framework). The standard industrial grade meets heavy-metal limits suitable for cosmetics (As <2 ppm, Pb <10 ppm), but always confirm the grade and obtain the appropriate documentation from our quality team before using in any cosmetic product.

Why does the color shift look weak on a white substrate?

Chameleon pigments rely on interference, which is most visible when competing white-light reflection from the substrate is minimized. On a white or light-colored base, the substrate reflects so much white light that the interference colors are diluted and appear pastel or washed out. For maximum effect, apply KT-95125 over a black or very dark basecoat—this allows the interference colors to dominate and produces the full blue-green-to-red shift.

Is this pigment suitable for outdoor automotive coatings?

Yes. KT-95125 is light-fast and heat-stable, with an inorganic composition (natural mica, iron oxide, silica) that resists UV degradation. For outdoor automotive use, always apply a high-quality clear topcoat with UV absorbers to protect both the pigment and the underlying paint film. The topcoat also enhances the visual depth of the color shift and shields the coarse particles from mechanical wear.
