TECHNIREZ® R1035 – High-Temperature Epoxy Casting Resin for Electrical Encapsulation

TECHNIREZ® R1035 is a pre-filled, solvent-free epoxy casting resin engineered for applications requiring elevated thermal performance and long-term electrical reliability. Designed to cure at ambient temperature when used with H2403 hardener, R1035 produces hard, resilient castings with excellent dielectric strength, mechanical toughness and thermal stability.

Optimised for electrical industry applications, R1035 is widely used for the encapsulation of instrument transformers, lighting transformers, small power transformers and the casting of electrical switchgear components. Its pre-filled formulation enhances casting flow, minimises shrinkage and ensures consistent, void-free encapsulation across a range of mould sizes and component geometries.

With its elevated thermal performance rating, TECHNIREZ® R1035 provides exceptional heat resistance, protecting sensitive electrical assemblies from thermal cycling, electrical load fluctuations and environmental stresses. The system delivers dependable performance in demanding service conditions, making it a trusted choice for high-integrity electrical casting applications.

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.
