RCF Polyurethane Injection Expanding Foam
RCF Polyurethane Injection Expanding Foam is a two-component, low viscosity, self-expanding polyurethane foam designed for sealing
cracks in structural materials including concrete, masonry and wood through low pressure, gravity feeding injection. It has been
designed to expand approximately 15 times its volume in non-confined, dry spaces.
2. WHERE TO USE
Use to fill voids and cracks in concrete, masonry or other substrates.
• Ideal for vertical repairs through injection ports
• No messy self-mixing through static mixer nozzle
• Interior and exterior applications
• Low viscosity – easy to inject and flows into small cracks
•Conveniently fits dual cartridge epoxy gun
• Moisture tolerant and blocks moisture
• Expands to fill voids with or without water
4. SHELF LIFE / STORAGE
Shelf Life is 1 year from date of manufacturer.
5. TECHNICAL DATA
|Expansion (in dry conditions, unconfined)||15 times original volume|
|Color||Yellow – Brown|
|Brookfield viscosity (cPs, RCVF #6 spindle @ 20 rpm, max)||450|
|Initial point of expansion/working time (77°F or 25°C)||3 minutes|
NOTE: The above properties are typical characteristics not to be considered as specifications.
6. CURING TIME
RCF Polyurethane Injection Expanding Foam has a working time of 3 minutes at 77°F (25°C). At temperatures below 77°F (25°C) this
product will take proportionately longer time to begin expanding. At temperatures above 77°F (25°C) it will take a proportionately
shorter time to begin expanding. Thin layers (5 mil) will become tack-free in approximately 45 minutes 77°F (25°C).
7. LIMITATIONS & WARNINGS
40°F (5°C) to 110°F (43°C). If ambient temperature is below 70°F (21°C), condition the cartridge to 70-75°F (21-24°C) for at least 1 hour before
8. CONDITION PRODUCT
When the work environment or substrate falls below 70’F (21’C) condition the product to 70-75’F (21’C – 24’C) prior to use.
Temperature will affect the workability and cure time of epoxy.
Dispense product through the supplied static mixing nozzles into injection ports.
10. LIMITATIONS & WARNINGS
• Minimum age of concrete must be 21-28 days from date of placement depending on curing and drying conditions.
• Subject to discoloration upon exposure to UV light
11. MANUFACTURER’S PRINTED INSTALLATION INSTRUCTIONS
For complete installation instructions on various applications using RCF Polyurethane Injection Expanding Foam, visit www.rhinocarbonfiber.com or call Rhino Products for more information at 1-888-684-3889
12. SURFACE PREPARATION
Remove dust, dirt, grease, laitance, curing compounds and other foreign matter by sandblasting, mechanical abrasion or hydro blasting.
For drilled holes, clean with a nylon bristle brush. Remove all water and dust with clean compressed prior to installation. RCF Polyurethane Injection Expanding Foam has a low viscosity to reach most cracks, and upon expansion, will penetrate all thin cracks.
13. CLEAN UP
Clean tools and equipment with Tough Wipes by Rhino, a biodegradable formula, that removes and neutralizes the epoxy. Do not allow
epoxy to harden on equipment as cured material can only be removed mechanically
