Borosilicate Glass Pigments

Technical Description

The Borosilicate Series is engineered by precisely depositing metal oxides onto ultra-thin, highly transparent borosilicate glass flakes. Unlike traditional mica-based pigments, the glass substrate features a significantly higher reflection index and an exceptionally smooth surface.

• Optical Performance: The high transparency of the glass flakes allows light to penetrate deeper into the coating layer, resulting in enhanced three-dimensional depth and a multi-color "starry night" sparkle.

• Substrate Uniformity: The manufacturing process ensures a large, smooth flake shape that minimizes light scattering, producing a cleaner, more intense reflection than natural mica.

• Chemical & Thermal Stability: These pigments are chemically inert and heat-resistant, maintaining their structural integrity and optical properties even in high-temperature plastic extrusion or automotive baking cycles.

Key Features & Benefits

• Diamond Sparkle Effect: Provides an extremely high level of brilliance and "fire," even at low pigment loading levels.

• Exceptional Transparency: The transparent base allows for clean color mixing with organic pigments without the "milky" or "cloudy" appearance often associated with natural mica.

• Smooth Surface Morphology: Reduces friction in printing and coating equipment, leading to better flow and leveling in final applications.

• Superior Color Purity: The lack of background color in the borosilicate substrate ensures that the interference colors remain vivid and true to the desired hue.

Industry Solutions

Traditional pearlescent pigments can often appear "flat" or "cloudy" when used in high-transparency systems, such as clear coats or lip glosses. Furthermore, achieving a high-sparkle "glitter" look usually requires metal foils or large plastic glitters, which may suffer from poor chemical resistance, conductivity issues, or environmental concerns.

Kolortek’s Solution: Our Borosilicate Glass Pigments offer the perfect balance of transparency and extreme brilliance. Because the substrate is essentially micro-glass, it disappears into transparent binders, leaving only the "starry" sparkle visible. They are non-conductive, UV stable, and chemically resistant, making them a safe and high-performance alternative to traditional glitters for both automotive and cosmetic formulators.

With 20 years of manufacturing experience, Kolortek ensures that our glass-flake pigments maintain a consistent thickness and particle size distribution. This precision prevents "seeding" or clogging in spray guns and printing plates, ensuring a smooth production run and reducing waste for our global partners.
