Flash Green Mica Pigment, 10–100μm – KT-6057

Flash Green Mica Pigment, 10–100μm – KT-6057

Pearlescent Pigments › Multicolor Series › Natural Mica (KT-6000)

KT-6057 is a Flash Green natural mica pearlescent pigment in the 10–100μm particle size range — the coarser-format green grade in the KT-6000 Multicolor Series, optimized for applications where visible individual-platelet green sparkle is required alongside the silver specular reflection characteristic of the series. The 10–100μm distribution spans both the fine fraction (contributing green pearl background coverage) and the coarse fraction (contributing visible individual flash points) — producing a green pearl surface with pronounced sparkle that the standard 10–60μm grade does not achieve at equivalent loading. Epoxy flooring, decorative coatings, nail lacquer, and craft resin are the primary application contexts.

Product Positioning — Flash vs. Standard Green Pearl

Within the KT-6000 green sub-family, particle size determines whether the green pearlescent effect reads as a smooth coverage sheen or a bold sparkle with individual flash points. KT-6057 Flash Green at 10–100μm is specifically the flash-sparkle grade — it shares the same green colorant deposition as the standard 10–60μm green grades but the extended coarse fraction shifts the visual output toward a pearl-plus-flash character. The table below shows KT-6057's position within the full KT-6000 green range.

KT-6000 Green Range — Color and Particle Size Overview

KT-6057 is the only coarser-format (flash-sparkle) grade in the standard KT-6000 green range. All other KT-6000 green grades are at 10–60μm standard particle size. For bold green sparkle in epoxy and decorative applications, KT-6057 is the correct specification within the natural mica green range.

Technical Specifications

Technical Characteristics

10–100μm — pearl coverage plus flash sparkle in one grade: The fine fraction (10–40μm) in KT-6057's distribution contributes a continuous green pearl background — these platelets are too small to resolve individually under normal viewing conditions. The coarser fraction (40–100μm) contributes visible individual silver-green flash points. Both effects operate simultaneously at standard loading levels: a green-toned pearlescent surface with bright sparkle superimposed. This is the key advantage over using the standard 10–60μm grades for epoxy and decorative applications where visible sparkle is required.

Green color visible on any substrate: The light-absorbing green colorant layer deposited onto the TiO₂-mica base produces green body color independent of substrate. Unlike KT-235 Green Pearl interference pigment (which shows green only on dark substrates), KT-6057 reads green over white, cream, dark, and transparent bases. For epoxy systems and decorative coatings where the substrate or resin base varies between projects, this substrate independence is a practical formulation advantage.

Mixing protocol — protect the coarse fraction: Add KT-6057 at the letdown stage after all high-shear dispersion steps are complete. The coarse platelets in the 40–100μm range are particularly susceptible to fracture from tight-clearance pumps and high-speed dispersers. Mechanical damage reduces the effective D50, which eliminates the flash sparkle character and leaves a flatter green pearl without visible individual flash points. Low-shear paddle or anchor mixing is required.

Kolortek has produced the KT-6000 Multicolor Series for over 20 years with consistent colorant deposition uniformity and D50/D90 particle size control across production batches. For applications requiring higher substrate purity and fewer dark mineral inclusions, the synthetic mica equivalent KT-7435A Flash Green (Fluorphlogopite, 10–100μm) is available in the KT-7000 series. TDS and SDS are available on request for both grades.

Frequently Asked Questions

Q: What is the difference between KT-6057 Flash Green and the standard 10–60μm green grades (KT-6050 to KT-6056)?
A: The standard 10–60μm green grades produce a smooth, balanced green pearl with soft shimmer — the fine fraction dominates and the effect reads as continuous coverage. KT-6057 at 10–100μm retains the fine fraction for background coverage but adds a coarse fraction (40–100μm) that produces visible individual silver-green flash points. The visual difference is significant in epoxy floor and resin art applications where the added coarse platelet sparkle creates a dimensional, multi-point flash effect. For applications where smooth green pearl is preferred over visible sparkle, specify one of the 10–60μm grades instead.

Q: Is a synthetic mica Flash Green available?
A: Yes. KT-7435A Flash Green (Fluorphlogopite, 10–100μm) is the synthetic mica equivalent in the KT-7000 series — offering higher substrate purity, fewer visible dark mineral inclusions, better luster and chroma, and higher thermal stability. Contact Kolortek to compare KT-6057 and KT-7435A for your specific application requirements.

Q: Can KT-6057 be used in printing ink applications?
A: No — the 10–100μm particle size range is not compatible with standard gravure, flexo, or digital press nozzle specifications. For green pearlescent printing ink, specify a fine-grade green from the KT-6000 series with confirmed D90 below 25μm. Contact Kolortek to identify the appropriate fine-grade green for your press configuration.
