KINETIX® R135 – Ultra Clear, Bio-Based Surfboard Laminating & Filler Epoxy System

KINETIX® R135 is an ultra-clear, UV-stable, high-performance epoxy system designed for premium surfboard laminating & filler/hot-coat applications. Engineered to deliver industry-leading cosmetic clarity with exceptional mechanical strength, R135 produces bright, crisp, bloom-free finishes ideal for modern surfboard construction.

Developed as a bio-based, solvent-free formulation, R135 incorporates renewable feedstock and components derived from existing industrial by-products. The cured system contains an independently verified 26% bio-based carbon content, providing surfboard manufacturers with a high-performance, environmentally conscious alternative to conventional epoxy.

R135 cures rapidly at room temperature and is suitable for laminating timber, EPS & PU foam blanks with E-glass, flax, carbon and hybrid fibre reinforcements. Its excellent UV resistance, low odour, fast fibre wet-out and superior yellowing resistance make it an ideal choice for clear, coloured or composite performance surfboards.

When paired with KINETIX® H135 Fast Hardener, R135 delivers polyester-like production speed with epoxy-grade clarity, strength & durability — enabling surfboard builders to achieve premium results without compromise.

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.
