TECHNIREZ® R2200 – Fire-Retardant High-Temperature Epoxy Infusion Resin

TECHNIREZ® R2200 is a solvent-free, low-viscosity epoxy infusion and laminating resin engineered for applications requiring fire retardancy and high-temperature performance. Formulated for use with H2403 hardener, R2200 delivers excellent thermal and mechanical properties following post-cure, making it suitable for demanding composite structures where flame resistance is critical.

Optimised for resin infusion and laminating processes, R2200 provides controlled flow characteristics and reliable fibre wet-out, supporting the manufacture of high-quality laminates with consistent structural performance. The system is suitable for infused and hand-laminated components where elevated service temperatures and compliance with fire performance standards are required.

When post-cured to specification, TECHNIREZ® R2200 achieves high glass transition temperatures (Tg) and strong thermal stability. The system complies with UL94-V0 flame-retardant requirements, with laminate thickness and post-cure schedule playing a critical role in final fire performance. As application configurations vary, suitability should be confirmed in consultation with ATL Composites technical representatives.

Typical applications include infused and laminated composite structures, panels, tooling, and components used in industrial, transportation, marine, architectural, and advanced manufacturing environments where fire performance and thermal resistance are essential.

frequently asked questions

How does ATL tailor composite systems for different industries?

Every industry has distinct performance, compliance, and manufacturing requirements. ATL’s in-house chemists and engineers develop and refine epoxy systems, adhesives, and core materials to meet the specific demands of marine, defence, aerospace, automotive, industrial, civil, architectural, and sporting applications — ensuring every product delivers optimal strength, efficiency, and durability.

Can ATL customise materials for my project or process?

Yes. ATL offers custom formulation and process engineering support to align material performance with your production requirements — whether infusion, hand lay-up, lamination, bonding, or CNC-routed panel construction. Our technical team collaborates closely with customers to deliver precision-matched resin systems and structural solutions for unique applications.

Are ATL’s composite systems certified for high-performance applications?

Absolutely. ATL operates under an ISO 9001:2015-certified quality management system, with selected materials approved by DNV for use in structural and high-load applications. Every ATL system is manufactured to exacting standards of performance, consistency, and traceability to meet the demands of defence, industrial, and advanced engineering environments.

What makes ATL’s materials suitable for large-scale or structural builds?

ATL’s epoxy systems, structural panels, and composite cores are engineered for high strength-to-weight performance, dimensional stability, and fatigue resistance. These attributes make ATL materials ideal for large composite assemblies, modular structures, and precision-engineered components where long-term strength, weight reduction, and reliability are essential.

Does ATL offer sustainable or bio-based composite options?

Yes. ATL is committed to advancing sustainable composite technology, offering USDA-Certified Bio-Based epoxy systems and environmentally conscious materials that reduce waste, extend service life, and minimise environmental impact. Our ongoing R&D focuses on improving sustainability without compromising structural integrity or mechanical performance.

How can I select the right ATL system for my application?

Choosing the ideal composite system depends on your structure’s design, load requirements, manufacturing process, and environmental exposure. ATL’s in-house engineers and chemists provide tailored advice to ensure the correct combination of resin, core, adhesive, and surface technology for your project.
To discuss your application or request technical guidance, contact ATL’s Technical Team — we’ll help you identify the most effective and efficient composite solution for your build.
