TECHNIREZ® R2517 General Purpose – Versatile Room-Temperature Laminating Epoxy System

TECHNIREZ® R2517 is a solvent-free, liquid epoxy resin designed for reliable general-purpose laminating across a wide range of ambient conditions. Formulated for use with either H2430 Fast or H2431 Slow hardener, the system cures effectively between 15°C and 60°C, allowing fabricators to tailor working time and cure speed to suit specific environmental or production requirements.

The R2517 system provides consistent wet-out, dependable adhesion and strong mechanical performance, making it suitable for laminating fibreglass, timber, and other composite substrates in marine, industrial, and construction applications. Its smooth handling and user-friendly processing profile make it ideal for small workshops, repair environments, and production settings where predictable cure behaviour is essential.

Solvent-free and easy to mix, TECHNIREZ® R2517 delivers a clean, controlled lamination process with low odour and reduced environmental impact, while maintaining the durability and performance expected from ATL’s proven epoxy systems.

– Built For Any Conditions. Designed For Every Laminate.

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.
