KEY PERFORMANCE TECHNIGLUE® R5 Structural Epoxy Adhesive
High-strength, toughened epoxy adhesive for critical composite and metal bonding.
TECHNIGLUE® R5 is a high-performance, solvent-free structural epoxy adhesive engineered for reliable bonding across composites, metals, timber, carbon fibre, fibreglass and engineered substrates. The toughened formulation delivers exceptional bond integrity, excellent impact and peel strength and superior resistance to micro-cracking, ensuring long-term durability in demanding applications.
Designed for room-temperature cure, R5 features a thixotropic, gap-filling consistency that is easy to apply on vertical or uneven surfaces while maintaining precise bond lines. The advanced chemistry enhances fatigue and impact resistance, making it ideal for bonding carbon fibre, Kevlar®, fibreglass and a wide range of metals.
Widely used across marine, transport, industrial and architectural sectors, TECHNIGLUE® R5 is suited to structural assemblies, composite components, metallic interfaces and prefabricated systems where strength, durability and reliability are critical.
ENGINEERED FOR MULTI-MATERIAL STRUCTURAL BONDING
KEY PERFORMANCE TECHNIGLUE® R5 Structural Epoxy Adhesive
When using TECHNIGLUE® R5, all bonding surfaces must be clean, dry, and free from grease, dust, and loose particles. For optimum bond strength, the adhesive must be able to fully wet both substrates. This is best achieved by preparing the surfaces to a uniformly roughened, matt finish, promoting strong mechanical adhesion.

TECHNIGLUE R5 FAQs
Can TECHNIGLUE® R5 bond carbon fibre to aluminium?
Yes. TECHNIGLUE® R5 is designed for structural bonding across composites and metals, making it suitable for applications such as bonding carbon fibre components to aluminium where high fatigue resistance, peel resistance, and long-term structural reliability are required. Surface preparation remains critical for best results.
Is TECHNIGLUE® R5 suitable for marine applications?
Yes. TECHNIGLUE® R5 is designed for structural bonding across composites and metals, making it suitable for applications such as bonding carbon fibre components to aluminium where high fatigue resistance, peel resistance, and long-term structural reliability are required. Surface preparation remains critical for best results.
What makes TECHNIGLUE® R5 different from standard epoxy adhesives?
TECHNIGLUE® R5 is a toughened structural epoxy adhesive engineered to improve resistance to peel forces, fatigue, and micro-cracking. Compared with more general-purpose epoxy adhesives, it is better suited to demanding structural joints exposed to movement, vibration, or repeated load cycles.
What industries is TECHNIGLUE® R5 used in?
TECHNIGLUE® R5 is suited to composite, marine, transport, industrial, and advanced manufacturing applications where strong structural adhesion is required between composites, metals, and other engineering substrates.
How does TECHNIGLUE® R5 compare to G/flex-type adhesives?
TECHNIGLUE® R5 is positioned as a structural bonding solution for applications requiring higher confidence in peel resistance, fatigue durability, and engineering-grade joint performance. Product selection should still be based on substrate, load case, service environment, and processing requirements.
