What is Astro 6415 RED?
Astro 6415 Red is a low-viscosity epoxy saturant engineered for high-temperature electrical insulation and composite applications. This Class H bonding and insulating resin is designed for continuous operation up to 180°C and cures to a tough, mechanically robust solid that reinforces and consolidates porous substrates.
Based on the proven Astro 6415 chemistry, the red-tinted version enhances visual inspection during application while maintaining the same performance in saturation, bonding, and thermal stability.
When should Astro 6415 Red be used?
- when a Class H epoxy saturant is required for electrical insulation systems
- when complete wet-out of porous substrates like glass, mica, or carbon is critical
- when extended working time is needed for generator winding or coil processing
- when visual confirmation of saturation improves quality control
- when compatibility with red insulation coatings is desired
Key properties of Astro 6415 Red
- Class H insulation resin (180°C thermal rating)
- Very low viscosity for deep substrate penetration and efficient saturation
- Long working (pot) life for large or complex applications
- High mechanical strength for reinforced electrical assemblies
- Long shelf life (up to 2 years at room temperature)
- Non-CMR formulation profile
- Red tint for improved visibility during saturation and processing
Typical applications
Astro 6415 Red is a versatile epoxy saturant used in generator winding resin systems, motor insulation, and high-performance composites. Typical applications include saturating cording and stranding for mechanical ties, bonding woven glass and mica insulation, and consolidating electrical laminates.
It is widely used in generator manufacturing and rewind operations across steam, hydroelectric, and wind turbine systems, as well as in electric motors and composite structures requiring high-temperature mechanical reinforcement.
