Pearlescent Pigment: A Decorative Material with Pearl-like Luster
Pearlescent pigment is a type of decorative material that exhibits a pearl-like luster. It is typically composed of natural mica, synthetic mica, or glass flakes as the base, coated with one or more layers of metal oxides (such as titanium dioxide or iron oxide). Its unique layered structure creates a pearl-like, shell-like, or metallic luster through the interference, refraction, and reflection of light.
Main Characteristics
1. Optical Effects
Pearlescent pigments can produce a soft pearl-like luster or a shiny metallic luster, depending on the particle size and coating thickness.
2. Physical and Chemical Properties
Pearlescent pigments are non-toxic, heat-resistant, lightfast, acid- and alkali-resistant, non-flammable, and non-conductive, making them an environmentally friendly material.
3. Particle Size Effect
Larger particle sizes typically result in a stronger shimmering effect, while smaller particle sizes produce a soft satin-like luster.
Applications
1. Cosmetics Industry
Used in products such as eyeshadows, lip glosses, and foundations to enhance shine and add a three-dimensional effect.
2. Coatings and Inks
Applied in automotive, bicycle, and architectural decorative coatings, as well as printing inks, to provide unique luster to products.
3. Other Fields
Used in crafts, ceramics, rubber, and more.
