Pigments Powder for Exterior Paints
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Specialized Exterior Coating Solutions
Deqing Demi Pigment Technology Co., Ltd. provides the architectural coating industry with pigments that stand the test of time. Our exterior-grade powders are manufactured to rigorous standards for lightfastness and weatherability. We understand that exterior paints are a building's first line of defense, and our pigments contribute to both the aesthetic beauty and the protective longevity of the coating system. Our products are widely used in premium facade paints and protective industrial coatings globally.
Exterior Coating Usage
- Facade Paints: High-durability coloring for residential and commercial buildings.
- Roof Coatings: Reflective and decorative pigments for metal and tile roofs.
- Wood Stains: Fine pigments for semi-transparent and solid exterior wood finishes.
- Masonry Coatings: Alkali-resistant colorants for stucco and concrete surfaces.
Exterior Paint Technical Specs
| Property | Metric | Standard |
| Lightfastness (1-8) | 8 | ISO 105-B02 |
| Weather Resistance (1-5) | 5 | ISO 105-A02 |
| Oil Absorption | 18 - 25 | g/100g |
| pH Value | 6.0 - 9.0 | ISO 787-9 |
| Tinting Strength vs Std | 98 - 102% | ISO 787-24 |
Core Characteristics for Façades
- Maximum UV Resistance: Inorganic structure provides a permanent shield against solar fading.
- Chalking Resistance: Does not catalyze the breakdown of the paint binder.
- Chemical Stalwartness: Resistant to acid rain, alkaline masonry, and atmospheric pollutants.
- High Opacity: Excellent hiding power allows for fewer coats and better coverage.
Q: Do these pigments prevent the paint from peeling?
A: While peeling is usually a binder or substrate issue, our pigments ensure the paint film remains chemically stable, which indirectly aids in long-term adhesion.
Q: Can these be used in high-VOC solvent paints?
A: Yes, our inorganic pigments are completely resistant to all standard paint solvents and do not bleed or migrate.
Formulation and Stability Testing
We offer accelerated weathering tests (QUV) for our pigments in specific client paint formulations to demonstrate long-term color retention before full-scale production.
Custom Dispersion: We provide "Easy-Disperse" grades that have been surface-treated to reach target Hegman fineness in up to 30% less time in high-speed dissolvers.
Solar Reflectance and TSR Management
Exterior color science is increasingly focused on "Cool Roof" technology. We provide pigments with high Total Solar Reflectance (TSR) to help keep buildings cooler in summer. By analyzing the spectral reflectance from 300nm to 2500nm, we can formulate exterior colors that look dark to the eye but reflect significant portions of the Near-Infrared (NIR) spectrum. This data helps paint manufacturers meet modern energy-efficiency regulations and improve the lifecycle of the building envelope.
