Why is Araldite® LY 8615 / Aradur® 8615 the benchmark for high-temperature epoxy systems in advanced composites?
✨ Market Trends
As aerospace, defense, and high-performance tooling industries shift toward lightweight yet thermally stable composite structures, demand for high-temperature infusion systems with superior mechanical integrity is rapidly accelerating.
✨ Applications
Araldite® LY 8615 / Aradur® 8615 is engineered for use in vacuum-assisted resin transfer molding (VARTM), RTM, and SCRIMP processes. It is ideally suited for manufacturing aerospace-grade composite parts, high-temperature molds, and structural components where dimensional stability and thermal endurance are critical.
✨ Highlights
This two-component epoxy system boasts a low mixed viscosity (550 mPa.s at 25°C) for excellent fiber wet-out, a prolonged pot life of 18 hours at room temperature, and a remarkable glass transition temperature (Tg) exceeding 217°C after post-cure. When reinforced with carbon or glass fiber fabrics, the system exhibits exceptional flexural strength and modulus up to 695 MPa and 42.9 GPa respectively.
✨ Product Advantage
Araldite® LY 8615 / Aradur® 8615 delivers a unique blend of low viscosity for effortless infusion, robust thermomechanical performance, and outstanding chemical resistance. Its high Tg and compressive modulus ensure structural integrity under sustained thermal and electrical stress, making it a preferred choice for advanced composite tooling, electrostatic shielding applications, and heat-resistant electronic housings.
