TECHNIREZ® R2529 – Abrasion-Resistant Thixotropic Epoxy Gelcoat System

TECHNIREZ® R2529 is a solvent-free, thixotropic epoxy system specifically formulated for tooling, mouldmaking and pattern-making applications where a tough, abrasion-resistant gelcoat is required. When used with H2429 hardener, the system cures reliably at ambient temperature to produce a resilient, high-strength surface layer capable of handling repeated tooling cycles and mechanical wear.

R2529 provides excellent hold-up on vertical and contoured surfaces due to its thixotropic rheology, ensuring consistent film builds without sagging. Its durable cured surface offers excellent adhesion, strong impact resistance and long-term dimensional stability, making it suitable for gelcoat layers on tooling boards, mould faces, patterns and composite tooling components.

Designed for professional composite fabrication environments, TECHNIREZ® R2529 delivers a clean, solvent-free processing experience with predictable handling characteristics and high-quality surface performance.

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.
