FX-646 Sprayable Aliphatic Polyurea Coating

DESCRIPTION:

FX-646 Sprayable Aliphatic Polyurea Coating is a two component sprayable aliphatic polyurea. It dries in seconds to provide a tough chemical and abrasion resistant coating. As an aliphatic polyurea, FX-646 is color fast and will resist yellowing from Ultra Violet light exposure. Typical working times of one minute or less can be expected. This fast reaction requires a fast, efficient mixing technique so that the mixture can be applied within the short gel times. Impingement mixing from available two-component spray machinery is efficient and entirely adequate.

ADVANTAGES:

Fast cure. Minimal downtime. May be walked on within 60 seconds.
Excellent adhesion to a variety of substrates.
100% solids, no VOC, low odor
Seamless and waterproof
Resistant to many chemicals
Flexible: will bridge cracks
High thermal stability of temperatures up to 350°F.
Unlimited DFT in a single application.
Cures from -20°F to 225°F

SURFACE PREPARATION:

Contact Fox Industries Technical Representative for detailed surface preparation guideline requirements.
Each individual application or installation is unique.
General surface preparations guidelines:

Steel:
Immersion Service: Minimum SSPC-SP10, Near-White blast cleaning.
Non-Immersion Service: Minimum SPC-SP10, Near-White blast cleaning

Concrete:
Allow new concrete to cure 28 days. Abrasive blast all concrete and refer to SSPC-SP13/NACE 6 Standard. Concrete must be clean, dry and sound with a sufficient profile.

Galvanized and other substrates (Geotextile applications):
Surface preparation will vary depending on exposure. Consult with a Fox Industries Technical Representative for specific guidelines or instructions.

APPLICATION:

Specialized plural component spray equipment is needed. Please consult with Fox Industries for proper equipment procedures and information.

Use only heated plural component equipment capable of producing 2000 to 3000 psi and 2 gallons per minute output consistency with approximate material heaters.

Maintain temperature at a range of 140°F to 160°F. A 50% overlay on each spray pass of the gun is recommended to avoid holidays, pinholes and achieve consistent film thicknesses.

A cross hatch spray pattern is strongly encouraged.

PACKAGING:

FX-646 is packaged in a 10 gallon or a 100 gallon units.

SHELF LIFE:

Six months minimum when stored at 75°F and dry conditions.

STORAGE:

FX-646 MUST BE TSTORED IN a dry, well protected and suitable storage environment with a TEMPERATURE BETWEEN^ 60 and 85°F. Protect from freezing.

SAFETY:

Refer to MSDS sheet prior to use.

CAUTION:

Contains organic isocyanates MDI. Avoid breathing vapors. Avoid contact with skin and eyes. Do not ingest. Keep away from foodstuffs and wash thoroughly before smoking or eating. Should skin contact occur, wash skin well with soap and water. Should eye contact occur, flush thoroughly for at least 15 minutes with water. Get medical attention.
