ABOUT THIS ITEM
ORCA® Hardener RFE is added to ORCA® Glue neoprene adhesive just before use. It improves the adhesion, cohesion and above all the heat resistance of the bond. It is designed to bond the Hypalon (CSM) and neoprene fabrics of RIB tubes, tenders and inflatable structures, such as ORCA repair fabrics.
- What it is for: activating ORCA® Glue for a repair, a patch or fitting a rubber accessory.
- Mixing ratio: 5 to 10% of the glue volume, i.e. 50 to 100 ml per litre.
- Contents: 750 ml, enough to activate 7.5 litres of glue at 10%, or 15 litres at 5%.
- For a small repair: the glue + hardener kit contains 1 L of glue and the matching dose of hardener.
Hardener dosage
Add 5 to 10% hardener to the volume of glue. From 10 litres of mixed glue, reduce to 5% to extend the pot life of the mix.
| ORCA® Glue | Hardener at 5% | Hardener at 10% |
|---|---|---|
| 1 L | 50 ml | 100 ml |
| 5 L | 250 ml | 500 ml |
| 25 L | 1.25 L | 2.5 L |
Once mixed, the glue can be used for about 1 hour. Allow 250 to 300 g of glue per m² bonded.

Gluing a patch: the ORCA method
- Work between 17 and 28 °C, with relative humidity below 70%.
- Sand both surfaces in one direction only, to remove the shine without reaching the fabric weave. Brush off the dust.
- Clean with solvent (MEK or toluene), then wait 10 minutes.
- Mix the glue with 5 to 10% RFE hardener. For more than 10 litres of mix, keep the hardener at 5%. The mix can be used for about 1 hour.
- Apply a first coat to both surfaces and wait at least 10 to 15 minutes, until the glue no longer sticks to your finger.
- Apply a second coat to both surfaces, wait 10 minutes, then join the parts while the glue is still tacky.

Safety precautions
The hardener is highly flammable. Work in a well-ventilated area, away from any flame or spark, and do not smoke. Wear gloves and safety glasses, and close the can tightly after each use.
Frequently asked questions
How much hardener for 1 litre of glue?
Between 50 and 100 ml, i.e. 5 to 10% of the glue volume.
Can ORCA® Glue be used without hardener?
No. ORCA® Glue is a two-part adhesive: it must be activated with RFE hardener to reach its full adhesion.
How long can the mix be used?
About 1 hour after mixing the glue and the hardener. Only prepare the quantity you need.
Is this glue suitable for a PVC tube?
It is designed for Hypalon and neoprene. For a PVC tube, contact us before ordering.
