VFI®-6040 40 D HP/LP Impact Resistant Hard Coat

Equipment

VFI recommends a high-pressure, plural component spray rig run at 150°F-155°F and 2,000 psi of constant pressure. Gun tips vary and will need to be adjusted on site. The following can meet 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 any oils, dirt, or films that may affect adhesion.

• 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 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 use, bring the material to a minimum temperature of 65°F. The B side (Poly) must be premixed until uniform before spraying. The time it takes to mix will depend on volume and mixing method.

Application Guidelines

The temperature should be between 40°F – 100°F application. The cure speed will increase if the temperature passes 72°F. VFI recommends spraying 80 mils for the best results. As a final step for texture, spray over but not directly onto the surface until the desired finish is achieved. Allow the material to set for at least 20 minutes before painting. A flexible paint must be used to avoid cracking. Once cured, it is ready to be placed into service after 24 hours. Allow 5 days for full cure.

Cleanup

VFI recommends using xylene or MEK when cleaning spray equipment. Flush the cleaning solution through spray lines until the bed liner is completely removed.

Storage/Shelf Life

Store between 60-90°F in a clean, dry building. The shelf life of unopened containers is 12 months after the date of manufacture. When in use, attach a desiccant cartridge to both drums to prevent moisture from entering the mixture. The Iso side can be nitrogen purged if you store it after opening.

Precautions

This material contains isocyanate, which can irritate the skin and is toxic if inhaled as particulate matter. Do not thin or add foreign material to this product. Avoid prolonged breathing of vapors and repeated skin contact. Use in a chemically approved spray booth with all necessary PPE, including a supplied air respirator or respirator with forced air ventilation. See the Safety Data Sheet for all safety information.
