What high refractive index materials are used in the Star Diamond series pearlescent pigments?
The specific high refractive index materials used in the Star Diamond series pearlescent pigments usually depend on the manufacturer's specific formula and product design. Generally speaking, the high refractive index materials used in pearlescent pigments may include the following:
Titanium Dioxide (TiO2):
Titanium dioxide is a common high refractive index white pigment. It has good optical properties and can effectively reflect and scatter light. In pearlescent pigments, titanium dioxide is often used to enhance the whiteness, gloss and hiding power of the pigment.
Metal oxides:
Metal oxides such as iron oxide and aluminum oxide have high refractive index and good optical properties. They are used in pearlescent pigments to produce metallic luster and specific color effects, such as metallic silver, metallic gold, etc.
Metal particles:
Some pearlescent pigments may contain tiny metal particles, such as silver, copper, aluminum, etc. These metal particles have high reflectivity and refractive index, which can produce unique metallic luster and high reflective effect.
Silicates:
Silicate materials have high refractive index and can provide good transparency and heat resistance in pigments. They are often used in pearlescent pigments to enhance the optical effect and stability of the pigment.
Special coatings and treatments:
Manufacturers may also use special coatings or treatments to improve the optical properties and durability of the pigment. These coatings can increase the flatness and smoothness of the pigment surface, further enhancing its ability to refract and reflect light.

What are the functions and advantages of the multi-layer structure of the Star Diamond series pearlescent pigments?
The multi-layer structure design of the Star Diamond series pearlescent pigments is to achieve more complex and excellent optical effects. The design of this multi-layer structure generally includes the following functions and advantages:
Enhance the reflection and refraction of light:
The multi-layer structure can maximize the reflection and refraction of light by precisely controlling the refractive index and thickness of each layer. This design enables the pigment to show a bright shining effect at different angles and lighting conditions, enhancing the visual three-dimensional sense and depth.
Color optimization and control:
Different layers of materials can have different optical properties and color effects. By adjusting the material type and thickness of each layer, the color performance of the pigment can be precisely controlled to create colorful visual effects such as metallic luster, sequin effects or rainbow colors.
Improve durability and stability:
The multi-layer structure design can enhance the surface hardness and wear resistance of the pigment, thereby improving its stability and durability in long-term use. This is especially important for products that require frequent contact or external environment exposure, such as automotive painting or outdoor decorations.
Innovation and market competitiveness:
Through the design of multi-layer structure, manufacturers can not only improve the technical content and innovation of pigments, but also make their products competitive in the market. This technical advantage helps to meet the needs of different industries and consumers for high-end, high-performance products.
