VFI®-6060 60 D Impact Resistant Hard Coat

Equipment

Apply the material to the prepared surface using a plural-component high-pressure spray rig capable of spraying at 2,500 psi and temperatures between 135°F-150°F. Gun tips will vary by the project and will need to be adjusted on-site. The following machines are capable of meeting these specifications:

• Graco A-XP1 air sprayer provides up to 3,500 psi of constant pressure and 170°F with a 1.5 gal/min output and 210 ft hoses. Use with any Probler P2 or Fusion gun.
• Graco Reactor 2 E-XP2 electric sprayer provides up to 3,500 psi of constant pressure and 190°F with a 2 gal/min output and 310 ft hoses. Use with any Probler P2 or Fusion gun.
• Graco Reactor 2 H-XP2/XP3 hydraulic sprayers provide up to 3,500 psi of constant pressure and 190°F with 1.5 or 2.8 gal/min outputs and 310 or 410 ft hoses. Use with any Probler P2 or Fusion gun.
• PMC PHX-2 or 25 hydraulic sprayers, ideal for small or medium-scale applications, provide up to 3,000 psi of constant pressure and 190°F with outputs just under 2 gal/min and 210-410 ft hoses. Use with the AP-2 Air Purge, PX-7 Mechanical Purge, or Xtreme Spray Gun.

Surface Preparation

All surfaces must be clean, dry, and free of dirt, dust, and debris to ensure quality adhesion. The surface must be completely dry to prevent foaming and improper cure.

• Metal – Clean all surfaces with acetone or MEK and allow the cleaning agents to dry. Scuff all areas you are spraying with a wire cup brush sander, or 40-grit sandpaper. Avoid sanding to bare metal, as this can affect adhesion, causing the coating to peel over time. Use acetone or MEK again to clean surfaces and allow them to dry before spraying. While primers aren’t necessary on properly prepared surfaces, they can increase adhesion on other surfaces.
• Wood – The wood should be dry and contain less than 11% moisture; otherwise, it should be primed or mist-coated with a light dusting of the coating, followed by the main application.
• EPS/HDPU – The foam must be aged for at least 30 days so any gas can escape. We recommend using non-recycled EPS bead 2 PCF foam for an optimal cost-to-quality ratio, but 1-3 PCF is acceptable.

Mixing

Before spraying, mix the Poly (B side) until uniform and bring both components to at least 65°F.

Application Requirements

Apply the coating at a minimum of 30 mil passes. If additional coats are needed, they must be applied within the 15-minute recoat window. VFI recommends applying a compatible UV-stable paint after cure for complete UV stability. Coated surfaces can be placed into service after a minimum cure of 24 hours.

Cleanup

VFI recommends using xylene or MEK to clean application equipment. When flushing out spray lines, we recommend the VFI-8005 Pump Flush to remove all material from the hoses.

Storage/Shelf Life

Store between 60°F – 90°F in a clean, dry building. The shelf life of unopened containers is 12 months after the date of manufacture. Once opened, it should be used immediately. If you are storing after opening, the container must be nitrogen purged.

Precautions

VFI-6060 contains isocyanate that irritates the skin and is toxic if inhaled. Avoid prolonged breathing of vapors and repeated skin contact. The material must only be applied to dry surfaces, as moisture triggers the curing reaction and could affect the coating’s physical properties and appearance. Do not thin or add foreign material to the product. Use only with adequate ventilation. See Safety Data Sheet for complete safety information.
