Structural Epoxy Adhesive Performance
TECHNIGLUE® R85 is engineered for structural bonding applications where temperature resistance, durability and substrate versatility are essential.
The formulation delivers strong adhesion across both porous and non-porous materials, including metals, composites, ceramics and timber, enabling reliable bonding in mixed-material assemblies exposed to elevated temperatures.
Its thixotropic consistency ensures the adhesive remains in place during application, maintaining consistent bondline thickness while effectively filling gaps in irregular surfaces.
This makes TECHNIGLUE® R85 particularly suited to industrial, marine and transport applications, where structural performance must be maintained under heat, load and long-term service conditions.

Where To Use R85
R85 is specifically engineered for applications where temperature resistance and structural performance must coexist.
Typical uses include:
- Industrial equipment exposed to heat
- Transport and automotive structural bonding
- Marine engine bays and high-temperature zones
- Metal-to-metal structural bonding
- Composite-to-metal assemblies
- General structural bonding where thermal stability is critical
PERFORMANCE POSITIONING
Not all structural adhesives perform under heat.
TECHNIGLUE® R85 is formulated to retain mechanical strength and bond integrity in elevated temperature environments where standard epoxy adhesives can soften, creep, or fail.

TECHNIGLUE R5 FAQs
What is TECHNIGLUE® R85 designed for?
TECHNIGLUE® R85 is designed for structural bonding applications that require elevated temperature performance. It is a strong option where service conditions go beyond standard ambient-temperature adhesive use.
Can TECHNIGLUE® R85 be used in high-temperature applications?
Yes. TECHNIGLUE® R85 is intended for structural bonding where higher service temperatures are expected. Final suitability should be assessed against the required operating temperature, joint design, and cure schedule.
Is TECHNIGLUE® R85 suitable for engine bay or heat-exposed assemblies?
TECHNIGLUE® R85 is positioned for applications requiring improved elevated-temperature performance, so it may be considered for heat-exposed assemblies where conventional structural adhesives may not be suitable.
Why choose TECHNIGLUE® R85 over a standard structural epoxy?
TECHNIGLUE® R85 is selected when a project requires stronger retention of structural performance at elevated temperatures. It is intended for applications where temperature resistance is a key part of the adhesive selection process.
What should I check before specifying TECHNIGLUE® R85?
Before specification, confirm the required service temperature, cure schedule, substrate combination, and joint design. For critical applications, product data and validation testing should always be reviewed.
