TECHNIFILL™ R1170 – Lightweight Epoxy Edge-Filling & Hardware Insert Compound

TECHNIFILL™ R1170 is a lightweight, two-part epoxy paste system designed for edge-filling composite panels, rebated cores and structural details in marine, architectural and industrial composite construction. With a simple 1:1 mix ratio by volume, the resin and hardener combine to form a stiff, dough-like paste that can be easily mixed by hand and pressed directly into cored edges without slumping or draining.

As a pre-thickened system, R1170 eliminates the common edge-filling method of blending powder fillers into liquid epoxy—offering a cleaner, faster and more consistent application process. The system produces no exotherm in bulk mixes and delivers more than 20% weight savings compared to standard epoxy filler mixtures, making it ideal for high-performance composite structures.

TECHNIFILL™ R1170 also performs exceptionally well as an insert material for mounting hardware such as hinges, latches, handles and door locks. Screws drive easily into the cured compound, delivering strong retention comparable to plywood, timber or high-density foam inserts. Its reliable mechanical behaviour, ease of use and compatibility with a wide range of substrates make R1170 a highly versatile solution for composite manufacturers.

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.
