TECHNIREZ® R2600 – High-Temperature Epoxy Infusion Resin

TECHNIREZ® R2600 is a solvent-free, low-viscosity epoxy infusion resin engineered for the manufacture of high-temperature composite tooling. Designed for use with H2403 or H2409 hardeners, R2600 delivers excellent thermal and mechanical performance following post-cure, making it well suited to demanding elevated-temperature applications.

Optimised for resin infusion, R2600 provides controlled flow characteristics and excellent fibre wet-out, enabling the production of void-free, dimensionally stable laminates. The system is also suitable for casting and laminating where high heat resistance and structural stability are required.

When post-cured to specification, TECHNIREZ® R2600 achieves high glass transition temperatures (Tg), low shrinkage, and strong thermal cycling resistance. Typical applications include the infusion, casting, and laminating of pre-preg moulds, vacuum forming tools, jigs, fixtures, and other high-temperature composite tooling used in industrial, automotive, marine, aerospace, and advanced manufacturing environments.

– Strength Under Heat. Stability Under Pressure.

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.
