Recommend Application

Automotive	Based on its documented sparkle green appearance, bright pearl luster and controlled 20–100 μm particle-size range, iSuoChem® AS4609 natural mica-based green pearl pigment can be evaluated for automotive coating systems requiring a pronounced green pearlescent effect. Its free-flowing powder form and chemical stability support consistent handling during formulation and color matching.
Powder coating	iSuoChem® AS4609 green pearlescent pigment features a natural mica-based platelet structure, bright pearl luster and acid- and alkali-resistant performance under normal temperatures. For powder coating applications, suitable dispersion and processing conditions should be selected to preserve the platelet structure and achieve an even sparkle green finish.
Ink Application	AS4609 mica-based green pearl pigment may be evaluated for industrial printing ink systems where a bright green pearlescent effect is required. The pigment is water-insoluble, free-flowing and available with a controlled particle-size distribution, while compatibility, dispersion and final print performance should be confirmed in the specific ink vehicle before production.

Quality Control

To maintain reliable batch-to-batch consistency, iSuoChem® uses an automatic film applicator to prepare a color card for every production batch and compare it with an approved standard sample. As a professional green pearl pigment manufacturer and supplier, we can also simulate selected coating, powder coating and printing ink processes in our laboratory according to customer requirements. This quality-control and application-testing support helps customers evaluate AS4609 during formulation and R&D while enabling us to maintain consistent color, pearl luster and particle-performance standards across bulk orders.

How Natural Mica-Based Pearl Pigments Create Their Sparkle Effect

Natural mica-based pearl pigments create luster through a layered optical structure. Each particle uses a thin, transparent mica platelet coated with a high-refractive-index metal oxide, commonly titanium dioxide. The refractive-index differences between the surrounding medium, oxide coating and mica form multiple optical interfaces that reflect light.

When light reaches the platelet, part of it reflects from the outer coating surface, while another part passes through the coating and reflects from a deeper interface. Because these reflected waves travel different optical distances, they reinforce or cancel selected wavelengths through thin-film interference. This produces bright, angle-dependent pearl luster rather than the uniform appearance of a conventional opaque pigment.[1]

The visible sparkle forms at the particle scale. Flat mica platelets act as directional reflectors. Platelets positioned near the specular reflection angle direct concentrated light toward the observer and appear as bright points, while differently oriented particles return less light. Numerous localized reflections therefore create the characteristic depth and visual texture of pearlescent pigments.[2]

Coating thickness and platelet size control different aspects of the effect. The optical thickness of the oxide layer influences interference color, whereas platelet dimensions affect the size and visibility of individual highlights. Fine pearl pigment grades generally create a smoother sheen, while coarser grades produce more distinct sparkle. In coatings, plastics and printing inks, maintaining suitable platelet orientation helps preserve the clarity of the pearl effect.

FAQ

1.Do you have any Certification?

2.What is your package?

3.Is it organic or non-organic product?

It is inorganic pigment, so it is safe to human body. If eaten by mistakes, it will be out of human body without any harm.

4.What is the cost per kg/ package?

5.What would be the approximate shipping cost by air/sea?
