HY-FL20W is a premium two-component flexible hybrid structural adhesive engineered for demanding bonding applications that require both exceptional strength and long-term flexibility. Combining the fast fixture characteristics of cyanoacrylate (CA) technology with the toughness of epoxy and the flexibility of advanced elastomer technology, HY-FL20W provides durable structural bonds that continue to perform under movement, vibration, thermal expansion, and impact.

Supplied in a convenient dual-cartridge syringe, the two components are automatically mixed during dispensing to ensure consistent performance, easy application, and reliable curing.

Unlike rigid structural adhesives, HY-FL20W is specifically formulated to absorb stress caused by vibration, shock loading, and expansion or contraction of bonded materials. This significantly reduces the risk of bond failure in applications where movement cannot be avoided.

HY-FL20W bonds metals, plastics, composites, fiberglass, wood, ceramics, and many other engineering materials while offering excellent gap-filling capability and long-lasting environmental durability.

Manufactured in Canada, HY-FL20W is trusted by manufacturers, marine fabricators, transportation companies, sign builders, maintenance professionals, and advanced DIY users who require structural strength without sacrificing flexibility. General properties described here reflect the capabilities of flexible hybrid structural adhesive technology.

Why choose this product?

HY-FL20W is engineered for applications where traditional rigid adhesives may fail because of impact, vibration, or continuous movement. Its advanced hybrid technology combines the speed of cyanoacrylate, the structural strength of epoxy, and the flexibility of elastomer-modified systems to create durable, long-lasting structural bonds.
The adhesive helps distribute stress more evenly across bonded assemblies, reducing stress concentrations while maintaining excellent structural performance. This makes HY-FL20W an excellent choice for composite structures, transportation equipment, marine applications, architectural panels, outdoor signage, and mixed-material assemblies exposed to demanding service conditions. These performance characteristics are consistent with flexible hybrid structural adhesive systems used for dynamic applications.  Whether you’re manufacturing equipment, repairing fiberglass components, building architectural structures, or assembling products exposed to continuous vibration and environmental stress, HY-FL20W delivers reliable structural bonding with the flexibility needed for long-term durability.

For optimum bond strength:

1. Remove dust, grease, oil, wax, and loose contaminants.
2. Lightly abrade smooth surfaces when practical.
3. Ensure substrates are clean and dry.
4. Dispense the adhesive using the supplied static mixing nozzle.
5. Assemble parts within the working time.
6. Hold or clamp components until handling strength is achieved.
