Astro 4800 Series
Superior Dielectric Strength, Thermal Resistance & Adhesion
Optimized For Performance & Operator Safety
Astro Chemical recently introduced the 4800 series, an EHS friendly, next-generation coating designed for high-performance protection in power generation and industrial applications. Featuring superior dielectric strength, thermal resistance, and adhesion, the Astro 4800 series outperforms leading single-component industrial coatings.
Key Features & Benefits
- Exceptional Adhesion – Superior bonding to steel, copper, and interlayer surfaces.
- Enhanced Thermal & Dielectric Performance – Withstands high-heat environments while maintaining electrical insulation integrity.
- EHS-Friendly – Non-CMR (free from carcinogens, mutagens, and reproductive hazards) and non-hazardous for shipping, reducing regulatory concerns and freight costs.
- Versatile Applications – Ideal as a topcoat for high-voltage equipment, corrosion-resistant protection, and a general-purpose industrial coating.
Proven Performance: Comparative Testing Results
To assess performance, our lab tested Astro 4803 (red) against three leading, single-component industrial coatings. Results confirm Astro 4803 excels in adhesion, dielectric performance, and heat resistance, particularly under aged, high-heat conditions—key for large industrial motors and utility-scale power generation industries.
