Product info

KINETIX® R118 – Very Low Viscosity Infusion Epoxy System

KINETIX® R118 is a very low-viscosity epoxy resin engineered specifically for vacuum infusion processes such as SCRIMP, VARTM & RIFT. Its exceptional flow behaviour enhances fibre wet-out, enabling the production of high-strength, void-free laminates with excellent moisture resistance & long-term durability.

R118 can be paired with H103, H115, H120 or H126 hardeners to provide a full range of pot lives, cure profiles & mechanical properties. H120 & H126 deliver excellent room-temperature performance without post-cure, making them suitable for most composite infusion applications. H115 offers very fast reactivity with a crisp early cure, allowing demoulding in as little as five hours — ideal for experienced operators requiring vinyl-ester-like cycle times with epoxy-level performance.

For projects requiring extended pot life or higher thermal performance, H103 delivers significantly longer working time & achieves a high Ultimate Tg after elevated-temperature post-cure.

Compared with polyester & vinyl ester systems, R118 infusion systems offer superior laminate consolidation, virtually no shrinkage, reduced exotherm in thick sections, higher impact resistance, increased fatigue life & no requirement for chopped strand mat. Typical applications include high-performance yachts, masts, kayaks, sporting equipment & lightweight structural components.

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.
