TECHNIREZ® R2532 – Glass-Fibre Reinforced Epoxy Tooling Paste

TECHNIREZ® R2532 is a solvent-free, glass-fibre reinforced epoxy paste designed for tooling, pattern making and foundry applications requiring strength, temperature resistance and easy hand-working performance. Formulated for use with H2406 or H2421 hardeners, the system cures at room temperature to form a tough, durable laminate with excellent dimensional stability.

When mixed, R2532 produces a high-build, easily hand-workable laminating paste suitable for creating strong structural back-up layers on moulds and patterns. Its reinforced formulation delivers superior mechanical strength, reduced shrinkage and improved resistance to handling stresses compared to standard filled epoxy pastes.

For high-temperature applications, such as pre-preg moulds or elevated curing processes, pairing R2532 with H2421 hardener enables the production of tooling that maintains performance under elevated thermal loads.

Versatile, strong and simple to use, TECHNIREZ® R2532 is trusted for composite tooling, prototype moulding, foundry patterns and built-up structures requiring a robust, reinforced epoxy system.

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.
