High-Temperature Composite Repair Technology: Withstanding Extreme Heat without Sacrificing Structural Integrity
Helios 157 is designed for high-performance composite repairs in elevated temperature environments. It features a two-component epoxy resin system with a glass transition temperature (Tg) of 157°C, making it ideal for pipelines, tanks, and structures exposed to sustained heat.
Unlike many high-temperature systems, Helios 158 cures at ambient temperatures of 25°C and above, eliminating the need for external heat sources in most climates. This makes it especially well-suited to hot regions or applications where extended working time is required.
Helios 157 is reinforced with our quad axial E-glass fibre fabric, consisting of four layers aligned at 0°/90°/+45°/−45°, ensuring optimal fibre orientation regardless of geometry. This alignment maximises strength in the hoop direction, delivering superior structural reinforcement, impact resistance, and long-term thermal stability.
High-Temperature Stability for Industrial Applications: Helios 157 features a Tg of 157°C, making it ideal for pipelines, tanks, and structures exposed to elevated temperatures, ensuring long-term performance in demanding environments.
Optimized for Hot Climates & Ambient Curing: Designed to cure at ambient temperatures of 25°C+, Helios 157 is perfect for applications in hot climates, and applications where a longer working time is required.
Exceptional Mechanical & Thermal Properties: Formulated with high-performance epoxy resin, Helios 157 offers excellent mechanical strength, impact resistance, and superior wetting properties for optimal reinforcement.
Proven Quadaxial Reinforcement for Structural Integrity: Utilises the same highstrength quadaxial E-glass reinforcement as BioWrap 102, providing outstanding durability, load distribution, and abrasion resistance.
Versatile Repair & Protection Solution: Engineered for industrial pipelines, chemical processing facilities, and structural repairs, Helios 157 delivers long-term corrosion resistance, mechanical reinforcement, and high thermal stability.
At Icarus Composites, we make sure to test our Composite Materials to the most stringent industrial standards ensuring we deliver the highest quality composite pipe and tank repairs possible.
Our Composite Systems are qualified to both ISO 24817 & ASME PCC-2 to make sure they meet the requirements of both international standards.

Helios 157 is purpose-built for the repair and reinforcement of industrial assets operating in high-temperature environments.
It is ideally suited for pipelines, pressure vessels, and structural components within oil refineries, petrochemical plants, power generation facilities, and processing sites where operating temperatures regularly exceed standard repair material limits.
With its high glass transition temperature (Tg 157°C) and ambient-cure formulation, Helios 157 enables durable repairs without the need for hot work or external heat sources—making it especially effective in hot climates or areas with limited access.
Whether addressing corrosion under insulation (CUI), restoring structural integrity, or extending the service life of thermally stressed components, Helios 157 provides a robust, long-term solution compliant with ISO 24817 and ASME PCC-2 standards.
