Pigment Preparation By Wet Methods TRIZ Cases
- Pearlescent Pigment Coating to Resist UV Gloss and Color Loss
A rare earth oxide and silane top coating suppresses UV-driven photocatalytic gloss loss and color shift in pearlescent pigments.
- Multilayer Coated Metal Effect Pigments for Gassing and Shear Stability
A silica and phenyl-silane hybrid sequence helps metal effect pigments resist hydrogen evolution and shear damage.
- Black Pearlescent Pigment with Metal Layer and Oxide Coating
Continuous metal layer on sensitized substrate resolves the contradiction between hiding power and pearlescent luster in black pigments.
- Transparent Portion in Color-Rendering Layer for Metallic Sheen
A transparent portion within a color-rendering layer allows incident light to reach a metal reflector.
- IR-Reflecting Pigment with Transparent Coating for White Appearance
An aluminum core coated with a transparent layer and white pigments reflects infrared radiation while suppressing metallic appearance and corrosion.
- Alpha-Alumina Pearlescent Pigments with Multi-Coating Layer
Multi-coating layer on alpha-alumina crystals overcomes particle size uniformity trade-offs to enhance reflectance and color expression.
- Alumina Flake Effect Pigments with Metal Oxide Coatings
Metal oxide coatings on alumina flakes resolve chemical stability and agglomeration issues while maintaining pearlescent luster.
