Synstar Orange Synthetic Mica Colour Pigment – KT-7423

Synstar Orange Synthetic Mica Colour Pigment – KT-7423

Pearlescent Pigments › Multicolor Series › Synthetic Mica / Fluorphlogopite (KT-7000)

KT-7423 Synstar Orange is a synthetic Fluorphlogopite mica pearlescent pigment in the standard 10–60μm particle size range that delivers a warm orange absorption color at side and diffuse viewing angles alongside a silver-white specular reflection at the direct angle. As part of the KT-7000 Synstar series, it uses a high-purity Fluorphlogopite substrate — offering higher cleanliness, better luster, and fewer dark mineral inclusions than equivalent natural mica grades. At 10–60μm, KT-7423 covers coatings, nail lacquer, soap, epoxy systems, and decorative applications where a vivid orange pearlescent effect is the specification target.

Product Positioning — Orange in the Synstar Synthetic Mica Range

Within the KT-7000 Multicolor Series, KT-7423 Synstar Orange fills the warm orange hue position that sits between the red grades (KT-7415 Synstar Red) and the gold grades (KT-7421 Synstar Gold, KT-7422 Crystal Gold). It is distinct from the KT-6070 / KT-6071 / KT-6072 orange range in the natural mica KT-6000 series — KT-7423 uses synthetic Fluorphlogopite for higher substrate purity, better luster-to-coverage ratio, and improved batch-to-batch color consistency. For applications where clean orange pearl on any substrate is required and substrate quality affects the finished result, KT-7423 is the appropriate specification.

KT-7000 Synstar Warm Color Range (10–60μm)

For orange at larger particle sizes with flash sparkle character, contact Kolortek to discuss available coarser grades within the KT-7000 series. Flash grades for red (KT-7415A), scarlet (KT-7482), and rose red (KT-7483) are available at 10–100μm — an orange flash grade availability should be confirmed directly.

Technical Specifications

Key Technical Characteristics

Deposited colorant mechanism — orange on any substrate: KT-7423 deposits an orange light-absorbing colorant directly onto the TiO₂-treated Fluorphlogopite platelet surface. The colorant layer absorbs non-orange wavelengths at side and diffuse angles, reflecting orange body color independent of the substrate beneath. Unlike the KT-200 series interference pigments — which require a dark substrate to reveal their color — KT-7423 shows orange over white, cream, dark, and transparent bases. For coating and resin formulations where substrate color cannot be controlled, this is a practically important distinction.

Fluorphlogopite vs. natural mica for orange — the purity argument: Natural mica orange grades (KT-6070 to KT-6072 range) contain trace mineral inclusions that appear as dark specks distributed through the platelet mass. In finished applications — particularly nail lacquer and cosmetic powders where surface quality under close examination matters — these inclusions reduce the visual cleanliness of the orange color. Fluorphlogopite eliminates this: the synthetic substrate is produced from controlled raw materials without mineral impurities, allowing the orange colorant to express against a clean, uninterrupted pearl base.

Silver-orange dual-angle effect: At the specular angle, the TiO₂-Fluorphlogopite interface produces a silver-white reflection independent of the orange colorant layer. At ambient and diffuse angles, the orange absorption dominates. The combination produces a surface that reads as warm orange in most lighting but shows bright silver flashes at direct reflection — a visual depth that flat orange pigments (iron oxides, organic dyes) cannot replicate without the platelet geometry.

Kolortek has produced the KT-7000 synthetic Fluorphlogopite Multicolor Series alongside its broader pearlescent range for over 20 years, maintaining consistent colorant deposition and D50 particle size distribution across production batches. TDS and SDS are available on request for KT-7423.

Application Range

Formulation Notes

Low-shear addition: Add KT-7423 at the letdown stage after all high-shear dispersion is complete. Use low-shear paddle or anchor mixing for incorporation. High-shear equipment fractures the Fluorphlogopite platelets, reduces D50, and diminishes the orange absorption color saturation and silver specular clarity — both components of the dual-angle visual depend on intact platelet geometry.

Evaluating orange on your substrate: The orange color reads on any substrate color, but the visual balance between orange and silver changes with base color. Over dark bases, the silver specular contrast is highest and the dual-angle effect is most pronounced. Over white or light bases, the orange absorption dominates throughout the viewing range and the silver flash appears less distinct. Evaluate drawdown samples over your actual substrate before finalizing loading levels.

Frequently Asked Questions

Q: What is the difference between KT-7423 Synstar Orange and the KT-6000 natural mica orange grades?
A: The visual color and dual-angle effect mechanism are the same — both deposit an orange colorant on a TiO₂-mica base. The difference is substrate quality. KT-6000 natural mica grades (KT-6070 Saffron, KT-6071 Nacarat, KT-6072 Orange Yellow, KT-6712 Orange Red) use muscovite mica with trace mineral inclusions that appear as dark specks, particularly visible at close inspection or under magnification. KT-7423 uses synthetic Fluorphlogopite without these inclusions, producing a cleaner orange pearl. For standard decorative coatings and craft applications, the natural mica range is adequate. For nail lacquer, prestige cosmetics, and applications where substrate purity is a specification requirement, KT-7423 is the appropriate choice.

Q: Does KT-7423 work over white or light-colored bases?
A: Yes — the deposited orange colorant produces orange body color independent of the substrate beneath. KT-7423 reads orange over white, cream, and light-colored bases. The silver specular flash is less visually prominent over light bases (less contrast between flash and background), but the orange color itself is fully visible. Over dark bases, both the orange color and the silver specular component are visible simultaneously, producing the most visually complex result.

Q: Is an orange flash grade available at 10–100μm on synthetic mica?
A: The KT-7000 flash synthetic mica range currently lists flash grades for red (KT-7415A), scarlet (KT-7482), rose red (KT-7483), blue (KT-7484), jade (KT-7485), green (KT-7435A), and purple (KT-7419A) at 10–100μm. Availability of a flash orange grade at 10–100μm should be confirmed directly with Kolortek — custom or extended particle size variants may be available for volume orders.

Orange pearl character varies with substrate color, application method, and loading level — evaluating KT-7423 on your actual base material alongside the natural mica KT-6000 orange grades is the most direct way to confirm whether the synthetic mica purity difference is relevant for your application.
