Product FAQ & Technical Guide

Part 1: Product & Technical Support

Q1: What are the main components of your pearlescent pigments? How do they compare to natural mica?

Our pearlescent pigments use Synthetic Mica or Glass Flakes as the core substrate, coated with multiple layers of nano-scale metal oxides (such as Titanium Dioxide or Iron Oxide).

Compared to natural mica, our synthetic and glass-based pigments offer:

  • Higher Purity: Free from natural impurities.

  • Controllable Particle Size: More uniform distribution.

  • Superior Color Stability: Brighter and cleaner colors.

  • Safety: No risk of radioactive contamination; fully compliant with EU RoHS standards.

Q2: Do the products contain hazardous substances? Are they safety certified?

Safety is our priority.

  • All pigments have passed Oral Toxicity Tests (compliant with EU EN 71-3 standards) and are safe for use in cosmetics and food-contact packaging.

  • Our products are free from heavy metals, microplastics, and prohibited polymers (compliant with EU Regulation 2023/2055), meeting global chemical safety standards.

Q3: How do I select the right pearlescent pigment model for different applications?

We recommend selecting based on your end-use:

  • Cosmetics/Personal Care: We recommend the Pritty Clareium series (e.g., Arctic White 1690), which offers high color saturation and excellent skin adhesion.

  • Automotive Coatings: Choose high-temperature resistant Glass Substrate models (e.g., Gold Rush 3867), designed to withstand baking temperatures above 180°C.

  • Printing Inks: Use ultra-fine particle sizes (D50 < 5μm) to ensure uniform gloss and printability.

For specific parameters, please refer to our "Product Selection Guide."

Q4: Do pearlescent pigments discolor or decompose during high-temperature processing?
  • Glass Substrate Pigments: Withstand long-term exposure to temperatures up to 200°C.

  • Synthetic Mica Series: Maintain color stability at process temperatures up to 150°C.

Customized solutions for extreme high-temperature applications are available upon request.

Q5: Do you offer customization for colors or particle sizes?

Yes! We provide OEM customization services. We can adjust the metal oxide layers, particle size distribution (standard range: 10-150μm), and specific hues (e.g., Tech Silver, Solar Gold) to meet your needs. Sample delivery is available in as fast as 3 working days.

Q6: How can I evaluate the dispersion of pearlescent pigments in my formula?

We suggest the following verification steps:

  1. Pre-disperse the pigment at a 1-3% ratio in a solvent (e.g., ethanol or water-based emulsion).

  2. Process with a high-shear mixer for 5 minutes (speed ≥ 1000 rpm).

  3. Observe the suspension for light transmittance and gloss consistency.

Q7: Are the products compatible with Polyurethane (PU), Acrylic, and other resin systems?

Yes. Our Synthetic Mica and Glass Substrate pigments are widely compatible with Water-based, Solvent-based, and UV-curing resin systems. For special resins (such as Epoxies), we recommend a compatibility test—we offer free samples for verification.

Q8: Will pearlescent pigments affect coating adhesion or mechanical strength?

When used correctly, they will not negatively impact coating performance. We recommend:

  • Controlling dosage between 3-8% (excessive amounts may reduce opacity/hiding power).

  • Adding the pigment to the formula after pre-dispersion.

  • Ensuring curing conditions match the resin system requirements (e.g., UV lamp power, baking temperature).

Q9: How can I judge the quality of pearlescent pigments?

Key quality indicators include:

  • Particle Size Uniformity: Verified via laser diffraction.

  • Coating Integrity: Analyzed via XRD (X-Ray Diffraction).

  • Weather Resistance: Tested via QUV accelerated weathering.

  • Batch Stability: Color difference (ΔE) controlled within ≤1.5.

We provide lab reports or third-party test reports for every batch upon request.

Q10: Do you have successful application cases in New Energy Vehicles (NEVs) or 3C products?

Yes, we serve leading brands:

  • NEVs: Custom Gold Pearlescent (Gold Rush 3867) for wheel coatings at a top-tier EV manufacturer.

  • Consumer Electronics (3C): Pearlescent texture effects (Clareium Diamond 8011) for a major mobile phone brand's back panel.

  • Cosmetics: Matte pearlescent effect (Arctic White 1690) for an international beauty brand's cream blush.

Part 2: Knowledge Hub

Q11: What are Pearlescent Pigments?

Pearlescent pigments are flake-structured powders consisting of a substrate core and a coating layer. They generate a metallic or soft pearl-like luster through light refraction and reflection. The three most common substrates are:

  1. Natural Mica: Often contains impurities like iron and manganese, giving the powder a greyish tone.

  2. Synthetic Mica: Created by melting and calcining. Eliminates impurities for higher whiteness, purity, and a skin-friendly feel suitable for cosmetics.

  3. Glass Flakes (Calcium Aluminum Borosilicate): Known for high transparency, intense reflection, and extreme sparkle ("glitter" effect).

Q12: What are the application ranges?

  • Decorative Coatings: Enhances appearance with multi-color shifts and faux gold/silver finishes.

  • Automotive & Powder Coatings: Provides strong metallic textures and stable physical properties (up to 700°C for ceramics).

  • Plastics: Ideal for "Mold-in-Color" and metallic masterbatches. Surface treatments reduce dust and improve dispersion.

  • Cosmetics: Versatile use in eye shadows, pressed powders, and personal care. Water/Oil compatible.

  • Printing Inks: Suitable for most ink types, offering vivid colors and anti-counterfeiting properties.

Part 3: Troubleshooting Common Issues

Troubleshooting: Plastics - Loss of Pearlescent Luster?

Possible Cause: Pigment structure damage due to high shear or incorrect mixing.

Solutions:

  • Strictly control mixing time and speed to prevent surface damage.

  • Avoid combining with high-opacity pigments (e.g., TiO2), which block the pearl effect.

  • Use single-screw extruders where possible to minimize shear stress during injection molding.

Troubleshooting: Coatings - Uneven Dispersion?

Solutions:

  • Pre-dispersion: Soak and wet the pigment before adding it to the main mix.

  • Dilution: Add thinning agents to lower viscosity.

  • Additives: Incorporate specific dispersing agents to improve stability.

Troubleshooting: Powder Coatings - Low Transfer Efficiency?

Possible Cause: Separation of pearlescent pigment and base powder during spraying.

Solutions:

  • Bonding: Use bonded metallic powder (the most effective method).

  • Specialized Products: Use our encapsulated series designed for powder coatings to improve charging properties and texture.

Troubleshooting: Inks - Viscosity Increase?

Possible Cause: High oil absorption of the pigment or solvent evaporation.

Solutions:

  • Reduce pigment dosage or increase solvent content.

  • Use surface-modified pigments designed to lower oil absorption.
