Flash Purple Synthetic Mica Pigment, 10–100μm – KT-7419A

Flash Purple Synthetic Mica Pigment, 10–100μm – KT-7419A

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

KT-7419A is a Flash Purple synthetic Fluorphlogopite mica pearlescent pigment in the 10–100μm particle size range — the coarser flash-grade variant of KT-7419 Synstar Purple, designed for applications where visible individual-platelet purple sparkle is required alongside background pearl coverage. The 10–100μm distribution produces a two-layer visual: the fine fraction (10–40μm) contributes a continuous purple pearl base, while the coarse fraction (40–100μm) delivers bright individual silver-purple flash points. On the Fluorphlogopite synthetic mica substrate, the purple absorption color is expressed with higher purity and cleaner luster than natural mica equivalents — relevant for nail lacquer, epoxy flooring, decorative coatings, and resin art where individual platelet quality influences the finished surface appearance.

KT-7419 Purple Range — Grade Selection by Particle Size

Kolortek supplies Purple in the synthetic Fluorphlogopite series across two particle size grades. The choice between them is a visual and application-method decision, not a color difference — both use the same purple colorant on the same Fluorphlogopite substrate.

For applications requiring a finer grade (printing inks, airbrush), a 5–25μm grade may be available — contact Kolortek to confirm. The 10–100μm flash grade is not suitable for standard gravure or flexo printing nozzle configurations.

Technical Characteristics

10–100μm — dual pearl-plus-flash character: The distribution of KT-7419A produces two simultaneously active visual components. Platelets in the 10–40μm range are below the individual resolution threshold under normal viewing conditions — they contribute a continuous purple pearl background sheen. Platelets in the 40–100μm range are individually perceptible as distinct silver-purple flash events. At standard loading levels, both components are present: a purple-toned base with bright individual sparkle superimposed. Increasing pigment loading increases sparkle density without proportionally increasing individual flash intensity once the optimal platelet packing is reached.

Fluorphlogopite purity benefit at the flash grade: At 10–100μm, platelet sizes extend into the range where substrate quality begins to matter visually. In natural mica at the upper end of this distribution, trace mineral inclusions appear as dark specks within individual platelets — particularly visible in epoxy and resin art applications where the larger flash platelets are prominent design elements. Fluorphlogopite eliminates this issue: the synthetic mica substrate is produced without the mineral inclusions present in natural muscovite mica, so each large platelet produces a clean, uninterrupted purple-silver flash rather than a flake with visible inclusion spots.

Purple color across all substrate types: The deposited purple colorant layer on KT-7419A absorbs non-purple wavelengths and reflects purple independent of substrate color. Unlike interference purple grades (KT-219 Violet Pearl — KT-200 series), which show color only on dark substrates, KT-7419A's purple reads on white, cream, dark, and transparent bases. For epoxy systems and decorative coatings where base colors vary, this substrate independence is a practical specification advantage.

Mixing protocol: Add KT-7419A at the letdown stage after all high-shear dispersion is complete. Low-shear paddle or anchor mixing only. The coarse Fluorphlogopite platelets in the 40–100μm range are susceptible to fracture under high-shear conditions — mechanical damage reduces D50, eliminates the flash sparkle character, and shifts the visual toward a flatter purple pearl. Kolortek has maintained consistent colorant deposition uniformity and D90 particle size control across KT-7000 series production batches for over 20 years. TDS and SDS are available on request.

Frequently Asked Questions

Q: What is the difference between KT-7419A Flash Purple and KT-7419 Synstar Purple?
A: Both use the same purple colorant on the same Fluorphlogopite substrate — the only difference is particle size. KT-7419 Synstar Purple at 10–60μm produces a smooth, balanced purple pearl with uniform coverage and soft shimmer; individual platelets are not perceptible at normal viewing distances. KT-7419A Flash Purple at 10–100μm adds a coarse fraction (40–100μm) that produces visible individual silver-purple flash points superimposed on the pearl background. Choose KT-7419 for smooth pearl applications; choose KT-7419A when visible sparkle alongside pearl coverage is the design requirement.

Q: Why does the synthetic Fluorphlogopite substrate matter specifically for the 10–100μm flash grade?
A: At 10–100μm, the coarse fraction extends into a size range where individual platelet quality is visible to the naked eye — particularly in epoxy resin art and floor applications where large platelets act as visible design elements. In natural mica at this size range, trace mineral inclusions appear as dark spots within each platelet, interrupting the clean purple flash. Fluorphlogopite is manufactured from purified materials without these inclusions. The investment in synthetic mica purity delivers its greatest visual return at coarser particle sizes where platelet-level quality is perceptible.

Q: What other flash-grade synthetic mica colors are available?
A: Kolortek's KT-7000 flash range at 10–100μm includes KT-7415A Flash Red, KT-7435A Flash Green, KT-7482 Flash Scarlet, KT-7483 Flash Rose Red, KT-7484 Flash Blue, and KT-7485 Flash Jade — all on Fluorphlogopite substrate.
