- GENERAL APPLICATION INSTRUCTIONS
Apply ELASTAFLEX™ CR only to clean, dry, sound, surfaces free of loose particles or other foreign matter. ELASTAFLEX™ CR can be sprayed over a broad range of ambient and substrate temperatures. It is recommended that ELASTAFLEX™ CR be sprayed in multi-directional (north/south - east/west) passes to ensure uniform thickness.
STEEL: 4-5 mil anchor profile is best for maximum adhesion andvaries per application and conditions; adhere to proper SSPC standards.
NON-FERROUS METALS: Prepare surface in accordance to SSPC-SP16 (Brush-off Blast Cleaning of Non-Ferrous Metals),It is imparative that the user perform their own adhesion tests.
WOOD: Apply polyurea onto a clean, dry, and sanded surface; free from burrs, splinters and loose debris. (It is recommended to prime wood and other porous surfaces before application of heated, fast-set polyureas to reduce pin holing).
CONCRETE: Prepare concrete in accordance with SSPC/NACE Standards and SPI Concrete Prep Guide.
PREVIOUSLY APPLIED COATINGS: SPI recommends UB™(ULTRA BOND™) products over existing coatings that are pastthe recoat window and/or application over other coatings.

Gel ± 6 sec Tack Free ± 20 - 30 sec. Post Cure ** 24 hour Recoat 30 min. - 8 hours * All cured film properties are approximate since processing parameters, ad-mixture types, and quantities change physical properties of the cured elastomer. Elevated temperatures will accelerate the curing process and shorten the re-coat window.
** Test performed in a dry, static environment.
*** Complete polymerization to achieve final strength can take upto several days or weeks, depending on a variety of conditions or product type. All samples for above tests were force cured 48hours or aged for more than three weeks. It is recommended that the user perform their own independent testing.
The samples for tests were sprayed with Graco HXP3 @ 2,500psi (17 mpa) dynamic pressure at the gun. Primary heater andhose heat 170°F (77°C) Graco MP Fusion Gun with 29/29 mixing chamber and .040 ceramtip.

The polyol “B” component must be thoroughly powermixed each day, prior to use. Use a SPI folding blade mixeror equivalent equipment approved by SPI. Install mixer through the extra 2” bung hole provided on all “B” drums. Care must be taken not to cross contaminate the individual components with the mixing equipment. Using any thinner may adversely affect product performance.

EQUIP & MFGBoss - Standard 1:1 ratio, heated, plural-component equipment developing a minimum of 1700psi (11.72 MPa) dynamicpressure at the gun with heating capabilities to 170°F(77°C) will adequately spray ELASTAFLEX™ CR.
- Machines capable of producing a higher dynamic psimay be required depending on the service environment the ELASTAFLEX™ CR will be exposed to.
- Proportioning machine primary heater temperature 70°F (21°C).
- Hose temperature 160-170°F (71-77°C). A hose thermometer inserted under the insulation near the gun should read a minimum of 145-155°F (63-68°C).
- Physical properties will be enhanced when sprayed at higher pressure (3000 psi or more); and utilizing an impingement mix gun such as MP Fusion or GX7-DI gun.
- Do not use mixing chambers with output greater than 1.5 gallons per minute.
- LIMITATIONS
- ELASTAFLEX™ CR is for professional use only.
- ELASTAFLEX™ CR must be stored at temperatures between 60—90°F (15—30°C).
- Liquid temperature in containers/drums during application 70—100°F (21—38°C).
- Apply AQUASEAL™ when surface and air temperatures are above 40°F (5°C) and the surface temperature is at least 5°F (3°C) above dew point and rising.
- Avoid moisture contamination in containers. Containers should not be resealed if contamination is suspected. CO2 created pressure can develop. Do not attempt to use contaminated material.
- Undried air exposed to liquid components will reduce physical properties of the cured coating.
Note: The material supplied is a two component system(component “A”/component “B”, which is used to formulatethis product. The quality and characteristics of the finishedpolymer is determined by the mixture and application of thetwo components by the person applying the polymers.
Packaging & Availability

- COLORS
ELASTAFLEX™ CR is available in standard colors (*Sand,Light Gray, Medium Gray, and Black).
Note: ELASTAFLEX™ CR is an aromatic polyurea; therefore,as with all aromatics, superficial oxidation will occur. Aliphatic urethane and other suitable topcoats can be used where long-term color stability and increased longevity infull sun exposure are of critical importance.
