Alkaline Alumina Sol Used for Coating Material
- Product Description
Alkaline alumina sol is a colloidal solution of aluminum oxide (Al₂O₃) nanoparticles dispersed in water, characterized by its high stability, adhesive properties, and thermal resistance (up to 800°C). It is widely used as a coating material due to its unique physicochemical properties.

Key Features for Coating Application
Enhanced Adhesion & Hardness
Forms durable films on substrates (e.g., metals, glass, ceramics), improving coating adhesion and scratch resistance (pencil hardness up to 9H).
Alkaline pH (9–11) enhances bonding with metal surfaces (cross-cut adhesion test: 0–1 grade).
Corrosion & Wear Resistance
Acts as a protective barrier against water/oxygen permeation, extending coating lifespan (salt spray resistance > 2000 hours).
Used in marine, automotive, and industrial coatings for harsh environments.
Thermal Stability & Transparency
Maintains performance at high temperatures, making it suitable for heat-resistant coatings (e.g., furnace linings, aerospace).
Transparent formulations (>90% light transmittance) enable applications in optical coatings and architectural glass.
Typical Applications
Industrial Coatings
Anti-corrosive paints for pipelines, ships, and chemical equipment.
Functional Coatings
Heat-reflective films (infrared reflectance >80%) for energy-efficient buildings.
Electronics
Insulating layers and wear-resistant coatings for semiconductors and displays.
